Barrette EMPLOYER Counsel Management Board Secretariat HEARIN~ October 29, 1991 February 6, 7, 1992 Introduction By a grievance dated December 21,1990, Gilles 'Gratton, formerly a Building Caretaker with the Ministry of Agriculture and Food in Alfred, alleges a violation of Article 42 of the Collective Agreement. Mr. Gratton is totally disabled and is in receipt of long-term disability payments. These payments are calculated on the basis of an employee's salary at "the date of disability." The main issue in dispute in this case is the grievor's "date of disability," there being no issue as to how the payments should be calculated once that date is determined. In brief, the union took the position that "date of disability" meant the date that the employee actually began to receive his or her Long Term Income Plan benefits (hereinafter "LTIP"). The employer took the position that under the plain and clear language of the Collective Agreement, "date of disability" was the day the em.151oyee was medically determined to have become totally disabled. The employer also took the alternative position that the union was estopped from advancing an interpretation inconsistent with the longstanding practice of the parties. Before turning to the evidence, counsel for the employer raised two preliminary objections, one questioning the Board's jurisdiction to grant the remedy requested, the other dealing with the timeliness of the grievance. The Board reserved its ruling on both Objections. At the end of the day, a'nd for reasons which follow, the Board dismissed the second preliminary objection. Given our disposition on the merits of the case, it is not necessary for us to make a formal ruling on the first objection concerning the Board's jurisdiction in cases of this kind, although it is our view that the iurisdictional issue raised by counsel for the employer has now been settled, affirming positively the Board's authority to hear and 3 decide grievances relating to the alleged denial of benefits provided for in the Collective Agreement (See. for example, OPSEU (Sekhon) v. Ministry of Health (unreported decision of the Divisional Court dated September 9, 1986), Sekhon 418/83 (Saltman), ~ 1299/89 (Simmons) and Rhodes 866/90 (Dissanayake).) Before turning to the evidence presented in this case, it is useful to set out the relevant provisions of the Collective Agreement: ARTICLE 42- LONG TERM INCOME PROTECTION 42.1 The Employer shall pay eighty-five percent (85%) of the monthly premium of the Long Term fncome Protection Plan. 42.2.1 (a) The Long Term Income Protection benefit is sixty-six and two-thirds percent (66-2/3%) of the 1. employee's gross salary at the date of disability, including any retroactive salary adjustment to which the employee is entitled. 42.2.3 Long Term tncome Protection benefits commence after a qualification period of six (6) months from the date the employee becomes totally disabled, untess the employee elects to continue to use accumulated attendance credits on a day-to-day basis after the six (6) month period. 42.2.4 Total disability means the continuous inability as the resuit of illness, mental disorder, or injury of the insured employee to perform any and every duty of his normal occupation during the qualification period, and during the first twenty-four (24) months of the benefit period; and thereafter during the balance of the benefit period, the inability of the employee to perform any and every duty of any gainful occupation for which he is reasonably fitted by education, training or experience. ARTICLE 46 - JOINT INSURANCE BENEFITS REVIEW . COMMITTEE 46.1 The parties agree to continue the Joint Insurance Benefits Review Committee. The terms of reference are set out in Appendix 5 attached. The Evidence Many of the facts are not in dispute. The grievor began work with the Ministry of Agriculture and Food (hereinafter "the employer") on September 6, 1965. His last position with the employer was that of Building Caretaker, and his last day worked was April 15, 1988. On April 16, 1988, the grievor began to receive Short Term Sickness Pian Benefits as provided for by Article 52.1 of the Collective Agreement. These benefits were calculated on the basis of his hourly rate as it was in April 1988, namely $10.72 per hour. These Short Term Sickness Plan Benefits expired six months later on October 16, 1988. At that time, the grievor made use o.f his accumutated sick leave and in that way continued .to receive his full salary, (which was subsequently retroactively adjusted to $11.20 per hour for the period between January 1, 1988 and July 1, 1988, and then to $11.24 per hour for the period between July 1, 1988 to December 31,1988, and then to $12.54 per hour on January 1, 1989). The grievor's accumulated sick leave benefits expired on or about February 10, 1989. At that time, the grievor began to receive his LTIP. The LTiP amount was not, however, calculated on the basis of the salary including all of the retroactive adjustments; instead, it was calculated on the basis of his salary on his last day of work. When the retroactive salary increase to $11.20 per hour came into effect, the LTIP payments were recalculated. It is obvious that, for the purposes - of this case, the "date of disability" is a critical issue, for its determination will decide whether or not the grievor receives 66 2/3% of $11.20 per hour or 66 2/3% of $12.54 per hour. The griever applied for LTIP in advance of the expiry of his Short Term ' Sickness Plan Benefits and his accumulated sick leave. His application was made on ,June 10, 1988 and approved in August 1988 effective February 10, 1988, on the basis of muscle atrophy of his right arm and leg due to polio. The griever's application for LTIP indicates that the griever's date of "total disability commenced" on "April 18, 1988." There was no dispute in these proceedings with the fact that the griever is totally disabled. The gdevor gave evidence with the assistance of an interpreter. He has a grade five education, and he testified about some of the background of the case with respect to the filing of his grievance. Suffice it to say that the griever went to Florida in January 1990, and when he returned some time in March he found a notice respecting retroactive pay, and so he went to see the office manager where he used to work. The office manager, Mr. Clarence · Ouellette, advised the griever that he would look after it, and subsequently the griever received a check in the approximate amount of $5.00. The griever went back to see the office manager, and later received another cheque for the period between January 1,1989 and February 10, 1989. Some time thereafter, the griever spoke with the union steward, Mr. Bob Villeneuve, and asked him whether or not his LTIP benefits were being properly calculated given the retroactive salary 'increase. Mr. Villeneuve advised the griever to see his supervisor, Mr. Claude Gratton (no relation). Mr. Gratton told the griever that he was not responsible for LTIP, and sometime thereafter, the griever again spoke to Mr. Villeneuve, who wrote a Ietter on the griever's behalf because the griever can neither read nor write. This letter, which was introduced into evidence, is dated October 4, 1990, and is addressed to the Joint Insurance Benefits Review Committee (hereinafter "the Committee"). In the letter, the griever requests that his LTIP be calculated on the basis of his 1989 salary not his 1988 salary. The letter sates that it "is only fair that LTfP PAYMENTS should 0nly be based on the salary the individual was making the day prior to the official day he embarked on LTIP." The letter asks the Committee to review the grievor's claim. Mr. Villeneuve also testified about the filing of this. grievance, and he told the Board that he had some conversations with the grievor in September or October 1990. Mr. Villeneuve generally corroborated Mr. Gratton's evidence, and he testified that no objection about timeliness, was made before the Committee, or in the pre-hearing, or at any time prior to the arbitration of this case. The evidence of the grievor and Mr. Oueilette completed the union's case in chief, following which the employer called two witnesses. Ms. G. Chang testified on behalf of the employer. She has longstanding experience in the calculation and administration of benefits, and had responsibility for the processing of the grievor's application. In addition, Ms. Chang is a member of the Benefits Coordination Forum, which is an inter-ministry group that has as its objective the bringing together of benefit coordinators to discuss benefit issues. Ms. Chang testified that the administration of LTIP has not changed in any material way since she first began work in Human Resources in 1974. Ms. Chang told the Board that an employee must be totally disabled in order to qualify for LTIP, and she indicated that LTIP benefits do not commence until after a six-month waiting period. This waiting period can, as already noted, be extended by an employee using his or her attendance credits. According to Ms. Chang, the date of disability is the last day that the 7 employee was at work earning his or her regular salary, and in the instant case, that day was April 15, 1988. The gdevor's entitlement was calculated ir~ June 1988 after he submitted his application. The employer determined that the grievor was receiving an hourly rate of $10.72 per hour at that time, and this rate formed the basis for determining his LTIP entitlement. Subsequently, the grievor and other employees received a retroactive salary increase, bringing the grievor's salary to $11.20 at his last day of work. His LTIP benefits were then revised to incorporate this increase. Ms, Joan Dunn also testified on behalf of the employer. Ms. Dunn is the Senior Benefits Advisor in the Management Board Secretariat, and.is also a member of the Committee. Ms. Dunn testified that as.of June 1991 there were approximately 2500 bargaining unit employees on LTIP. Ms. Dunn adopted Ms. Chang's evidence and testified that the method of determining the date of disabifity has been the same for as long as she can remember. A number of documents were introduced into evidence including a brochure entitled: ".information for Civil Servants Who are Absent for an Extended Period Because of Illness or Injury." It states, in part, that "the plan pays a monthly benefit equal to 66 2/3% of your monthly gross pay at the date of disability, and includes any retroactive saiary change which is effective on or before the date you became disabled." Aisc introduced were a 1980 brochure which states that the LTtP pays "66 2/3% of the pay you were receiving on the day you became disabled;" an extract from the Manual of Administration, prepared in March 1986, which states in part; "The Long Term Income Protection Plan provides income for eligible employees following a qualifying period of six continuous months absence from the date of total disability;" a brochure entitled "Sick Leave and Insurance 8 Plans" distributed to all bargaining unit employees in 1986 and all newly hired employees thereafter, which states that the LTIP "pays a monthly benefit equal to 66 2/3% of your monthly gross salary at the date of your disability including any retroactive salary adjustments;" and a copy of the LTrP agreement between the employer and the Confederation Life Insurance Company. This latter plan indicates, in par[, that "upon receipt of due proof submitted during the 6 month period immediately following the Qualifying Period that an insured employee prior to his attainment of 64 years, 6 months of age became and remained totally disabled continuously for the Qualifying Period, Confederation Life will pay him the Monthly benefit." Ms. Dunn described the activities of the Committee, which include the discussion of policy issues, the consideratien of issues arising from claims and the review of financial reports from the insurance, carrier. Ms. Dunn noted that the Committee has both union and management representatives, and it serves as a forum for discussion of issues of mutual concern to the parties. The'LTIP came into effect in 1975, and Ms. Dunn testified that in preparation for this hearing she reviewed all the Committee files dealing with LTtP claims. The only issue relating to LTIP that she could find in the files was an expression of concern, in the summer and fall of 1990, relating to the indexation of LTIP benefits. Ms. Dunn also described a 1990 publication entitled "A Guide to Your Benefits" which was introduced into evidence. Ms. Dunn testified that she sent a copy of a draft of this booklet to Shirley McVittie, who is an OPSEU representative on the Committee, in October 1990. Ms. McVittie, who gave evidence in reply, subsequently raised some questions and concerns about this book[et, but none of these questions and concerns related the determination of the date of disability. A letter from Ms. McVittie to Ms. Dunn was introduced into' evidence and it supports this evidence. The relevant portion of this booklet states that LTIP benefits "are based on what your salary was on your last day of work, including any retroactive changes to your salary." Ms. Dunn testified that if the union interpretation of "date of disability" was upheld, it would likely require a new contract with the insurance carrier, along with an additional insurance expense. In cross-examination, Ms. Dunn was asked a number of questions about the implications of upholding the union's interpretation of date of disability, and it is fair to say that the evidence on the impact of such an interpretation is speculative at best. Ms. Dunn's evidence completed the employer's case. When the hearing resumed, Ms. Shirley McVittie was called to give reply evidence on behalf of the union. Ms. McVittie has been employed by. the union since 1974 and has been a benefits counselor since 1981. Her job includes counselling union members about benefit entitlement and assisting them in making LTIP claims. Ms. McVittie has served on the Committee since 1981, and she told the Board that there have been periodic changes to the insurance plan, which have involved amendments to that plan. Ms. McVittie told (he Board that she was on the Committee when it considered the grievor's insured benefits grievance under Article 27 of the Collective Agreement, and that no timeliness issue was raised at that time. Moreover, it was Ms. McVittie's evidence that there are many delays in the processing and consideration of LTIP claims, and that these delays'can be explained by the fact that the individuals in question are sick. At the Committee level, time limits have never been a barrier to the consideration of a claim. Ms. McVittie testified about the process in fiiing a claim, and pointed out that this process generally involves the employee, his or her doctor and the employer. In general, the union only becomes involved if there is some problem in the processing of a claim, or if a claim has been denied. To Ms. McVittie's knowledge, no one has ever grieved the issue in the instant case, and she suggested in her evidence that one reason for this might be because the jurisdiction of the Board to hear and determine benefits grievances has only recently been resolved. Ms. McVittie gave some speculative evidence about the number of persons who would be similarly situated to the grievor with respect to having the wage rate for their position change, but not be retroactive, between the last day of work and the receipt of the first LTIP payment. In Ms. McVittie's view, there would not be many people in this category, and she questioned Ms. Dunn's evidence that the union's interpretation of date of disability would have a negative impact on the premiums that were paid. In Ms. McVittie's view, the change could be made by an amendment to the contract, as other changes have been made in the past. Ms. McVittie also testified about the draft booklet sent to her by Ms. Dunn for comments in the fall of 1990. Ms. McVittie testified that the union has never Said that it agrees with the employer's interpretation set out in that booklet that date of disability means the last day of work', and the fact that Ms. McVittie did not raise anY disagreement with it in her letter to Ms. Dunn did not mean that she agreed with it. Ms. McVittie told the Board that her letter, in which she commented on some areas of disagreement with the interpretation set out in the draft booklet, was not intended to be completely comprehensive; rather, what it did was bring to Ms. Dunn's attention some of the issues that immediately struck Ms. McVittie when she read through the ~aft. Moreover, Ms. McVittie testified that the Committee had already di§cussed the Gratton case by this time, and so the employer was aware of the union position with respect to the date of disability. In cross-examination, Ms. McVittie testified that she has advised employees about how their LTIP benefits are calculated, and she agreed that she has tdJd employees that they are only entitled to retroactive salary increases that come into effect for the period the employee was actuaIly working. When there is no dispute about the medical evidence, MS. McVittie advises employees that the date of disability is the date the employee's doctor certifies that employee to be totally disabled. Ms. McVittie could not recall the Committee ever discussing the issue of how date of disability was determined, and told the Board that she had no knowledge of the union ever making any formal objections to the employer about the statements contained in the various booklets introduced into evidence. Ms. McVittie agreed that her evidence about whether or not the union's interpretation of date of disability would require re-tendering of the insurance contract, or additional premiums, was speculative, albeit based on her experience in the benefits area. The evidence having been completed, the case proceeded to argument. Union Argument Union counsel began by noting that while an employee is in the six-month waiting period for LTIP, premium deductions of 15% continue, and these deductions are based on the employee's salary. Accordingly, if an employee's salary increases in the' six-month period, but that increase is not retroactive, then the employee is left in the unfair situation of paying a higher percentage of his or her salary in premiums during the six months, but not receiving the benefit of those premiums when he or she eventually go~s on LTIP. Having made this point, which was further elaborated on later in argument, counsel turned to the other issues in dispute. In counsel's view, there were four issues before the Board that needed to bE, addressed: 1) the timeliness objection, 2) the determination of the date of diSability, 3) the estoppel claim of the employer, and 4) the Board's jurisdiction to award the remedy requested. With respect to the final issue, union counsel requested the Board, should it find for the grievor, to make a declaration to that effect, and remain seized with respect to the implementation of the award should the parties not be able to come to an agreement. With re. spect to the timeliness issue, counsel argued that the employer has waived any objection it may have had, and pointed out that'the union only received notice of this objection immediately prior to the first day of hearing. Moreover, counsel reviewed the grievor's evidence, and argued that by the fall of 1990, the grievor finally determined, after making a number of inquiries in the months previous to that, that he was not receiving what he considered to be his proper entitlement. He notified the employer of this within twenty days of making that determination, and accordingly the grievance was timely. Counsel also pointed out that this is not a case of a sophisticated grievor, and he observed that given the complicated calculations involved in determining LTIP entitlement, it was hardly surprising that it would take some time for the grievor to realize that he was being improperly paid. Counsel atso referred to Ms. McVittie's evidence, both to the effect that the timeliness issue was not raised at the Committee stage, and noted that many of these cases are technically out of time because the employees are totally disabled and often have other 13 priorities. Turning to the merits, counsel argued that the term "date of disability" under 42.2.1 refers to the first day that a claimant begins to receive LTIP benefits, and accordingly, that the grievor's benefits should be calculated on the basis of what his salary would have been in February 1989, not what it was on his ~ast.day of work in April 1988. Counsel argued that this in. terpretation could be maintained by the language of different subsections of Article 42. Counsel pointed out Article 42.2.1 refers to "date of disability," while Article 42.2.3 refers to the date that the employee becomes totally disabled, and Article 42.2.4, which defines total disability, does so in the context of both the pre- and post-qualifying periods. None of these provisions defined the term as the last day worked by an employee. What was required, therefore, was to consider the term in'. the context of this provision and in the cor~text of the benefit scheme more broadly construed. Counsel referred to the Short Term Sickness Plan described in Article 52. That plan provides for an employee to receive 75% of his or her salary during the six-month qualifying period, and this salary is paid on the basis of the wage fn effect at the time the employee is receiving the benefit. It is not based on the salary the employee was receiving on his or her last day of work. Counsel pointed out that employees, as was the.case with the grievor, can extend this period by using their attendance credits. The grievor was able to extend this period by approximately four months, during which time he was receiving a benefit based on the salary he would have been receiving if he was working. He was also making a benefit premium 'payment based on this higher salary. Counsel noted that the. effect of the employer's interpretation of date of disability in this case was for the grievor to falf backwards in salary when he began to receive his LTiP benefits, even though he had been paying a higher amount in premiums in the six-month waiting period and in the four month additional period which followed. Counsel argued that this could not have been the intention of the parties. In counsel's view, there were two important dates. The first important date was the last day of work. This date was important because it marks the start of the six-month waiting period. Just because an employeebegins the six-month waiting period does not necessarily mean that he or she will proceed inevitably to LTIP. He or she may recover. Alternatively, he or she may suffer another injury. Accordingly, the important day for determining the' date of disability, in counsel's view, is the first day of benefits. And that being the case, the grievor should have his benefits calculated on the basis of the Salary he would have been receiving if he had been working on that first day. Counsel also made some anticipatory submissions with respect to the employer's estoppel argument. Counsel referred to the law generally, and cited a number of cases to the Board including Re Elan Tool and Die. 18 L.A.C. (3d) 17 (Weatherill), Re Northwest Territories, 5 L.A.C. (4th) 1 (Chertkow), Re Monarch Fine Foods Co.. 18 L.A.C. 257 (Schiff), and Re Phs. rrna Plus Druamarts Ltd.. 14 L.A.C. (4th) 303 (Stanley). Counsel argued that while it was true enough that the union never contested the manner in which the employer administered the LTIP benefit,'there was never any deliberate or conscious acquiescence with the employer's practice. This sirence could not be described as a representation, and there was not, in any event, any detrimental reliance. In counsel's view, ,there was no evidence indicating that recognition of the union's interpretation would involve any additional premium expense, which would be shared by the parties according to the formula set out in the Collective Agreement. Very simply, in counsel's submission, the ingredients necessary for an estoppel had not been established. With respect to the most recent employer pamphlet and the statement therein defining the date of disability, counsel noted that Ms. McVittie testified that she did not intend her comments to be comprehensive, and that when she was asked for comments the instant grievance had already been filed putting the employer on notice that the union contested its interpretation. Counsel also observed that with this one exception, none of the brochures discussing eligibility for benefits introduced into evidence defined "date of disability" as an employee's last day of work. Employer Argument ' Employer counsel argued that the different provisions found in Article 42 were clear and unambiguous, when read alone, when read in context of Article as a whole, and when read in context of the benefit scheme generally. In the alternative, counsel argued that if the Board found that the clause was ambiguous, then the Board had the jurisdiction to look at past practice as an aid to its interpretation of the in~ention of the parties. Counsel also argued that the union was estopped from arguing an interpretation inconsistent with the interpretation that has been appiied and acquiesced in by the union since LTIP was first introddced in 1975. Counsel argued that the evidence established that the griever was totally disabled on April 1.8, 1988, and that his last day of work was April 15, 1988. The Board was referred to some medical records prepared by the griever's physician to that effect. This was, counsel argued, the "date of disability," and this was the date that the grievor's benefit crystallized. His LTIP was calculated based on his salary on this date, as adjusted for a retroactive increase. Counsel agreed that during the six-month waiting period, and for the approximate four months thereafter when the grievor used his attendance credits, he w~ts receiving benefits based on an increased salary, and that this increased salary was not used in the calculation of his LTIP when he began to receive those particular benefits. Counsel noted that the Collective Agreement provisions referring to the Short Term Sickness Plan provide for benefits based on "regular salary," and this is why the grievor was paid on that basis. In counsel's view, this had nothing to do with the date of disability, and the calculation of benefits based on salary at that date. Counsel also argued that the definition of "total disability" in Article 4.2.2.4 supported th'e employer's case, and that the grievor had been determined to be totally disabled in April 1988. He remained totally disabled throughout the qualifying period, and when it was over. When he had exhausted his attendance credits, he went on LTtP because he continued to be totally disabled. He did not become "totally disabled" immediately prior to going on LTIP; he had, counsel argued, been totally disabled since April, and that was, counsel submitted, his "date of disability." NO other interpretation made any sense, and counsel also argued that there was no provision in Article 42 or anywhere else in the Collective Agreement stating that an employee was entitled to anything other than his salary along with retroactive increases at the date of disability, The Collective Agreement did not provide that an employee was entitled to an LTiP calculated on the basis of the salary he or she would have received had he or she been working the day before the LTIP benefits began. In counsel's submission, the employer had properly calculated the grievor's entitlement, and he was receiving the benefits provided for in the Collective Agreement. Even assuming for the sake of argument, that the Collective Agreement provisions were ambiguous, counsel argued that the past practice supported the employer's interpretation of the provision. Counsel referred to the evidence of Ms. Chang and Ms. Dunn, and it was to the effect that the "date of disability" has always been interpreted to be the date at which an employee was no longer able to work because of total disability, and that this interpretation was verified by the various brochures and pamphlets introduced into evidence. Counsel noted that prior to the instant grievance, no complaints or concerns had been raised about this issue. Counsel made a number of submissions with respect to the timeliness of the grievance, and argued that the evidence indicated that the grievor did not file his grievance within the time mandated in the Collective Agreement. On this basis alone, counsel argued, the grievance should be dismissed. Counsel also argued that an estoppel had been established in this case, and she carefully reviewed with the Board the evidence and legal principfes which she submitted supported this assertion. Decision Before turning to the merits of this case, and to the different arguments advanced by the parties, it is appropriate to deal with the employer's preliminary, objection respecting timeliness. Under Article 27.9.1, a grievor must bring a complaint that he or she has been denied benefits provided for in Article 42 of the Collective Agreement to the attention of his or her supervisor within twenty days of first becoming aware of the complaint. While the evidence in this case indicates that the grievor may have had some inkling of a complaint upon his return from Florida in March of 1990, we are satisfied on the basis of the evidence which we heard, that he did not really became aware of his complaint until after he spoke with the office manager, with Mr. Gratton and with the union steward. As a result of these discussions, the grievor became aware of his complaint, and as soon as he did, certainly within the twenty days mandated' in the Collective Agreement, he filed a grievance with respect to it. While it is true enough that the grievor's evidence, and that of the union steward, was not entirely clear on what happened when, it should perhaps be borne in mind in this case that the grievor was totally disabled, that he has a very limited education, and that he cannot read or write. In these circumstances, and given the evidence that we heard, we find the grievance to be timely. In making this determination, the evidence of Ms. Shirley McVittie is worth bearing in mind. It will be recalled that she testified that virtually all the grievances with respect to benefits are !echnically out of time, and that this is hardly Surprising given.that the g. rievors are sick and, in the case of those who apply for LTIP, are totally disabled. Moreover, there is no evidence of any prejudice to the employer, nor were the employer's concerns raised until just prior to the hearing of this case. Accordingly, we dismiss the employer's timeliness objection and will now deal with the merits. Having carefully considered the evidence and arguments of the parties, we have come to the conclusion that this grievance should be dismissed. -Notwithstanding our considerable personal sympathy for the grievor, it cannot be said, on the evidence and arguments before us, that the Collective, Agreement has been infringed. If anything, the terms and provisions of that agreement have been properly applied and the grievor is receiving the benefits to which he is entitled, in reaching this conclusion, it is not necessary to deal with the estoppel argument raised by the employer, for we are satisfied that provisions in question are not ambiguous, and to the extent that the Collective Agreement can be characterized as ambiguous, the past practice of the parties provides evidence of their intentions. It is our view that "date of disability" must mean the date atwhich an employee is determined to be totally disabled by his or her physician. It cannot mean the date at which that employee begins to receive LTIP benefits, for to qualify for those benefits the employee must have been totally disabled for at least the six months prior, and, in the instant case, for that additional period of time in which the grievor was making use of his attendance credits. If the employee was totally disabled throughout the qualification period, it could hardly be said that his or her date of disability was the date immediately prior to receiving LTIP. Article 42.2.3 clearly states that LTIP will be paid six months after the employee becomes totally disabled. This can only mean that 6 months (or even longer if attendance credits are used) prior to the receipt of LTIP that the employee was totally disabled. And this earlier date is the date of disability. Very simply, the scheme set out in the Collective Agreement envisages an employee stopping work as a result of becoming totally disabled and then receiving short term sickness benefits for a six month period. If at the expiry of this period, the employee continues to be totally disabled, then he or she will have qualified for and will become eligible for LTtP benefits. These benefits will be calculated on the basis of the employee's salary, including any retroactive adjustm'ents, on the date the employee became disabled, which will, in most cases, be the date that the employee stopped working. This is exactly what took place in the instant case. This interpretation is also supported by the requirement that LTIP benefits be calculated so as to include any retroactive salary increases. The very fact that increases that are "retroactive" are included in determining the amount for LTIP calculation is further evidence that "date of disability" is the last day of work and not the day immediately, prior to the employee beginning to receive LTIP benefits. In our view, the evidence of past practice supports the interpretation of the Collective Agreement advanced by the employer. Given the unsettled state of jurisprudence with respect to the jurisdiction of the Board in benefits cases, it may not be surprising that there were no grievances filed in respect of this issue prior to the instant one. But at the same time, prior to this case, there were no concerns or questions about the practice of the employer, and there is no evidence that the union ever took issue with it. Instead, the evidence'indicates that since 1975 the employer has consistently interpreted "date of disability" in the manner followed in this case, and that the union has accepted that interpretation. Indeed, union representatives have counseled employees that "date of disability" is the date at which the employee is unable to continue working prior to the commencement of the six-month waiting period. To a more limited extent, the various brochures and pamphlets introduced into evidence provide further evidence of the practice, and ultimately the intention of the parties. Having reached this conclusion, it is not necessary for us to address the estoppel argument advanced by the employer. In denying this grievance, we note that there appears to be an anomaly in the fact that an employee will pay premiums on benefits received during the six-month waiting period, and during any extended period that might be available as a result of attendance credits, and that these premiums are based on the employee's regular salary, which, in the instant case, is a salary high%~r than the one used to cafculate the griever's LTIP entitlement. As union counsel noted, the griever paid these higher premiums but was then denied the benefit of those higher premiums when he went on LTIP, for his LTIP was calculated on the salary he received on his last day of work adjusted for a retroactive increase. In the instant case, this indeed appears to be true, but this is what the parties agreed to in their Collective Agreement. They agreed that LTIP would be calculated based on salary at date of disability, and they agreed that during the six-month qualifying period, employees will receive their regular salary and they will pay benefit premiums based on that salary. Accordingly, and for the foregoing reasons, the grievance is dismissed. DATED at Ottawa this 9th day of u,,,~'¢.u;?-z 992 William Kaplan Vice-Chairperson Member M. O'Toole Member
