Margaret Froh, Counsel Ann Wallace, Local President Jay Jackson, OPSEU Central Negotiator Sherry Johnston, Local Vice-President Hearing held in Kitchener, Ontario on April 27, 1998 Written submissions received on May 11 and May 25, 1998. Executive Session held on May 27, 1998. DECISION The grievance (Ex. 1) alleges a violation of Article 11 because the College has not given certain employees their proper vacation entitlement. There were no preliminary objections raised concerning jurisdiction or arbitrability. 2 This matter involves the calculation of vacation entitlement for support staff employees in the bargaining unit who had previously been excluded from the bargaining unit because they were part- time employees. There is no dispute between the parties conceming the practice which the College has always followed. No part-time employee who became a bargaining unit employee was given credit for service outside the bargaining unit for vacation entitlement purposes under the collective agreement or any of its predecessors. In 1986 there was an arbitration award between these same parties rendered by Arbitrator Palmer which dealt with seniority creditfor part-time service and which did not lead the College to change its practice of not recognizing part-time service for seniority credit. In 1990 Arbitrator Devlin dealt with the issue of seniority credit for part-time service in a decision involving Mohawk College. Following that award the parties negotiated Article 14.3 dealing with seniority when College employees transfer into the bargaining unit, in which they agreed that 'all those who tranSferred into the unit after November 14,. 1991 "shall have their seniority prorated upon completion of their probationary period". On January 22, 1996 there was a Support Staff Agreement Committee meeting attended by members of management and the local Union executive. The minutes of that meeting (Ex. 4) indicate that the parties discussed the matter of part-time employees as follows: Seniority for Part Time Employees Hired Prior to November 15, 1991 The Union tabled a memorandum from Sandi Johnson (Council of Regents) that Management had not yet seen. This is in reference to a grievance awarded at Mohawk College. Conestoga has 104 employees hired prior to November 15, 1991 who had previous part time work. Conestoga has computerized part time work history only since 1982. In addition, both Human Resources and Payroll have purged older records. 3 The Union understand that full seniority is to be given for part time work for employees hired' prior to November 15, 1991, and pro-rated seniority for employees hired since November 15, 1991. No specific definition of"full seniority" is available. Leave Replacement (Appendix D) contracts were confirmed as those contracts for which the employee works more than 24 hours per week. Conestoga's records indicate 23 employees hired since November t5, 1991 have had Appendix D seniority credited to them. Any weeks which have more than 24 hours/week will be deducted, thereby' reducing seniority dates for those employees. An agreement must be reached by both parties as to how 'previous part time work history (prior to computerized records of 1982) should be confirmed for applicable employees. The Union suggested a joint letter be submitted to E/ERC outlining our situation prior to 1982 and asking for direction/guidance. Management to contact Council of Regents and advise. The same group met again on February 22, 1996 and the minutes of that meeting(Ex. 5) show that they again discussed the matter of part time employees as follows: 01/96/04 Seniority for Part Time Employees Hired Prior to November 15, 1991 The Union questioned the status of this item. The Union believe there should be an agreement between Management and Union, but not necessarily at the local level. The Union understand E/ERC are discussing this subject. Management are working on this project. When completed, Management will post new seniority lists and ail individuals will be written to advise them their seniority date has/has not changed as applicable. The Union asked if vacation entitlement credits for the applicable part time seniority changes would be given. Management advised no college is applying this credit towards vacatiOn entitlement. On March 14, 1996 the same group met again and the' minutes (Ex. 6) disclose that they reached the following agreement regarding seniority: Seniority Management asked for Union interpretation of the OPSEU February 26/96 opinion/letter to Sandi Johnson, CofR. '4 It was agreed that: 1. For part time employees who transferred into the bargaining unit prior to November 15, 1991, Management have credited full seniority for days worked within the term of a part time contract, i.e. 7 hours ~ 1 day 2. Forpart time employees who transferred into the bargaining unit after November 14, 1991, Management have credited pro-rated seniority based on length of service as a part time employee. 3. It was agreed a part time employee is not an Appendix D leave replacement, nor someone working in a Project of an Non-Recurring Nature. 4. Prior to 1981, Conestoga has no computerized nor financial part time work history records that would prove hours were actually worked against a part time contract. It was agreed that in these cases, seniority would be calculated using the start and end dates of the part time contracts. 5. For part time contracts with working hours recorded against them, seniority would be calculated based on the actual hours worked within each contract (either full or pro-rated, as applicable). 6. It was agreed that item//3 in the OPSEU correspondence was not a complete statement. 7. It was agreed that Appendix D contracts do not attract seniority accrual. However, if for some reason, the employee's hours were reduced in a week to 24 or less, by definition that week's work becomes part time work and does then attract seniority accrual. 8. It was agreed to use a [illegible handwritten words omitted] 13 week break in service as part of the calculation method as this is the figure used in conjunction with a) Less Than 12 Month Positions - this is the maximum amount of time that the full time employee can be laid off annually b) this is the amount of time defined in the Employment Standards Act re: separate periods of employment for calculating termination notice. Management requested the Union co-sign the joint interpretation.memo to be distributed to all support staff concerning this issue. The Union reserved their agreement pending review of the memo contents. Both Ruth Jensen and Sherry Johnston were members of the committee representing the Union, and both of them attended all three meetings where the above matters were discussed. Jensen had been either Unit Steward or in a similar position since at least the mid 90's. Johnston was the local Vice-President and had been on the local executive since at least 1989. Both of them were employees whose seniority would be affected by 'the change. Both of them heard the College indicate that there would be no change in vacation entitlement. As agreed to at the meeting of March 14t~, all full time employees received a letter fi.om Delores Smith, Manager, Employee Relations & Classifications and Ann Wallace, President OPSEU Local 238, which was in fact co-signed by Smith and Johnston. The following is the portion of the letter which everyone received on or after April 3, 1996 (see Exs 7 & 8): The issue of the application of seniority has been raised provincially. At a recent local Support Staff Agreement Committee meeting, members were able to come to an agreement as to how seniority should be applied. This has resulted in a number of changes to the seniority list. A new seniority list has been produced and is posted. A person employed bythe College, who transferred into the bargaining unit has been accorded full seniority, based on length of service. As well, pan-time support staff employees transferred into the bargaining unit, prior to November 15, 1991 have received full seniority. After November 14, 1991, their seniority has been prorated, based on a proration of hours of the part-time position to the hours of the full-time position using 1820 hours per year as constituting the hours of the full-time position. Reference Article 14.3 of the current Support Staff Collective Agreement. For your information, no time records are available prior to 1981; full seniority has been accorded to all employees based on the part-time contracts found within their human resources file. Article 14.3 does not apply to ApPendix D employees as they are deemed to be in the bargaining unit and therefore cannot be transferred in; their rights are outlined exclusively in Appendix D of the collective agreement. A break in service of greater than thirteen (13) weeks in' length results in an employee not qualifying for transfer of seniority. The rationale being that this is the maximum length of time allowed for a temporary layoff as identified in the Less Than 12 Month Positions Letter of Intent in the current Support Staff Collective Agreement as well as the definition found in the Employment Standards Act related to separate periods of employment and termination notice. 6 It should also be noted that for purposes of the application of Article 15.4, supervisory personnel, and employees in the academic staff bargaining unit,' who transfer into the bargaining unit are entitled to exercise only that portion of their seniority, if any, accumulated as an employee in the bargaining unit or what formerly was the bargaining unit. The newly posted seniority list shall be considered correct for all purposes unless an employee disputes its accuracy by providing the Human Resources Department with written notice by April 26, 1996. If you have any questions regarding the interpretation of implementation of this article, please contact wither of the writers. · Both Jensen and Johnston received that letter. In addition, individual employees received notice of their new seniority dates and the Union did not see those individual-notices. Jensen received notice that her previous seniority date was September 15, 1989 and that her new seniority date was April 21, 1989 (Ex. 7). Johnston received notice that her preVious seniority date was December 14, 1982 and her new seniority date was February 11, 1981. In the letter hiring Johnston as a bargaining unit employee, dated December 14, 1982 (Ex. 9), the College stated the following regarding her vacation entitlement: Vacation - The vacation year for College Support Staff is from July 1 to June 30 of the following year. Annual vacation entitlement is fifteen (15) working' days after one full year of employment; Your vacation entitlement based on your service up to next June 30, 1983 is 8 days. She was given no credit for any previous nOn-bargaining unit service upOn becoming a bargaining unit employee in 1982. The College's records (Ex. 8) show that she had begun pan-time. employment in September 1980. In the letter hiring Jensen as a bargaining unit employee, dated July 31, 1989 (Ex. 10), the College stated the following regarding her vacation entitlement: VACATION - The vacation year for College Support Staff is from July 1 to June 30 of the following year. Annual vacation entitlement is fifteen working days after one full year of 7 employment. Your vacation entitlement based on your service up to next June 30, 1990, will be 13.5 day(s). After seven years' continuous service, an employee will be granted 16 days vacation, 17 days after eight years and 20 days for nine to eleven years' service. Employees with 12 or more years of service will receive an additional vacation for each additional year of service to a maximum of 25 days after 16 years. She was given no credit for any previous non-bargaining unit service upon becoming a bargaining unit employee in 1989. The College's records (Ex. 7) show that she had begun part-time. employment in January, 1989. Further, in 1991 Jensen's seniority, vacation entitlements, and anniversary date had been adjusted because she had been on long tenn. disability from August 23, 1991 to September 30, 1991. She received a notice to that effect (Ex. 11) on or after November 19, 1991 indicating the following: Vacation entitlement for the 91/92 accrual year is now 13.5 days. Seniority dates (sic) has been moved to September 15, 1989 Anniversary date has been adjusted to October 18, 1989 The College never received any indication from those two employees that an error had been made regarding their vacation entitlements. We have no evidence of any grievances having been filed concerning the calculation of Vacation entitlements from any employee who had previOus part- time service. It is clear from the evidence of Ann Wallace, the Local President, that the Union knew on February 22, 1996 that the College was denying its request to alter vacation entitlement credits for those employees whose seniority dates were being affected by previous part-time service. It is also clear that both Jensen and Johnston, two employees who would have been affected by the denial, were at the meeting and did not pursue the issue further. 8 The matter of vacation entitlements next arose in the February 26, 1997 Support Staff Agreement Committee meeting. The minutes of that meeting (Ex. 12) show the following: Vacation Entitlement/Previous Part Time Work (Georgian Award) Management have received and are reviewing the copy of a Georgian College arbitration award. Management indicated an arbitration award does not mean the decision is to be applied at every college. The Union are preparing a letter to their membership, advising that some members may be entitled to extra vacation entitlement as a result of this award. Management will indicate their position in terms of this award by the end of the week. The College indicated to the Union that vacation entitlements would not be adjusted on the basis of the Georgian College arbitration. The grievance (Ex. 1 ) was filed on March 7, 1997 with Johnston- signing both on behalf of the grievors and as Steward. It was Wallace's evidence that she did not know whether any members who had previous part- time service got credit for vacation entitlement rjr not. She did say, though, that she understood in 1996 that there would not be credit for seniority and service, although she did not agree that it would be fair to assume that the Union knew that the College was not giving credit for previous part-time service in relation to vacation entitlement. Those are the facts that relate to this particular grievance..We also heard evidence, regarding the negotiations which led up to the 1991-92 and 1992-94 collective agreements and received language from agreements spanning the period 1984 to 1992 (Exs. 2A to 2E inclusive). Both Wallace Kenny, who negotiated on behalf of the Council of Regents and who has been involved in negotiations since 1987, and Jay Jackson, who has been on the Union's provincial negotiating team since the 1984-85 agreement, testified. 9 Based on the evidence we heard fi.om both Kenny and Jackson we conclude that neither part- time seniority nor service was an issue between the parties until the round of negotiations following Arbitrator Devlin's award in the 1991 Mohawk College case. Prior to that, part-time service had not been credited for any purpose other than the probationary period when an employee transferred into the bargaining unit. It would appear that both the Council of Regents and the Union were concerned about the equity of the situation if transferring employees were granted seniority which recognized full credit for their pre-bargaining unit part-time employment. The inequity would have resulted because part-time employees would have accumulated seniority at a faster rate than full-time employees who had been in the bargaining unit throughout their employment. The Council of Regents proposed pro-rating service. The Union proposed pro-rating service as of the-date of ratification onwards and not retroactively, changing the effect of the Mohawk award. The parties agreed on that and the resultant amendment to Article 14.3. That article from the 1991-92 collective agreement (Ex. 2E) is reproduced below with the amendments underlined: 14.3 Transfer into Union A person employed by the 'COllege, who is transferred into the bargaining unit, will be accorded full seniority, upon completion of the probationary period, based on length of service. Part-time support staff employees transferred into the bargaining unit. after the date of ratification of this Agreement. shall have their seniority prorated, upon completion of their probationary period, based on a proration of hours of the part-time position to the hoUrs of the full-time position using 1820 hours per year as constituting the hours of the full-time position. It is understood, however, that for the purposes of the application of Article 15.4, supervisory personnel and employees in the academic staff bargaining unit, who are transferred into the bargaining unit shall be entitled to exercise only that portion' of their seniority, if any, accumulated as an employee in the bargaining unit or what formerly was the bargaining unit. During the negotiations for the 1991-92 collective agreement there was no discussion about giving credit for past part-time service for vacation entitlement. Kenny said that had the matter been 10 raised by the Union the parties would have had to negotiate the matter because it was contrary to the understanding of both parties that there would be such credit. Jackson confm'ned that the Union had not turned its mind to the issue of vacation entitlement and past part-time service, and that the entire focus of the discussion was-concerning seniority. He also said that he did not believe that the Union took any steps to see what was occurring at any of the colleges in relation to other part-time issues. During the negotiations for the 1992-94 collective' agreement (Ex. 3) Article 14.3 was unchanged save for inserting the actual date of ratification (November 14, '1991) into the provision. The issue of credit for pan-time service for vacation entitlement was not raised during those negotiations. During the negotiations in 1994 the issue of vacation entitlement fOr previous part- time service was also not raised. Clearly the Council of Regents did not believe that the Union thought it had the right under any of the collective agreements to have vacation entitlement based on previous pan-time servicel Jackson said that the issue of pan-time service and seniority was dormant until it became clear in late 1995 or early 1996 that there would be downsizing. It then became known that many of the colleges had not made the appropriate seniority adjustments for part-time service. Following that, the central Union raised the matter formally at the E/ERC along with the issue of vacation entitlements..The central Union learned then that there was no disagreement between it and the Council of Regents concerning seniority, but that they had different views about crediting past part- time service for vacation entitlement. The central Union then advised the locals that they should deal with their own colleges on seniority and service issues. This advice would have been given in late 1995 or early 1996. It was his understanding 'that a number of locals had launched grievances following discussions at their colleges. It was Jackson's evidence that the Union head office only became aware of the part-time service issue in relation to vacation entitlements in late 1995 or early 1996 following the query fi.om George Brown College which led to the formal E/ERC discussions. On January 20, 1997 an award was issued in the matter of an arbitration between Georgian College and the Union dealing with credit for previous part-time service for vacation entitlements. The majority of that board of arbitration, chaired by Arbitrator Schiff, awarded that "vacation entitlement as of June 30, 1996 shall be determined under art. 11.1 by including in the 'years of continuous service' the employee's period of time, if any, in a part-time job back to the date of hire into that job" (page 13). That grievance was launched on February 8, 1996 (see page 3 of award) at around the same time that the local Union in this case was told by the College that its request for crediting part-time service for vacation entitlement .was being ·denied. As already noted, the grievance here was launched following the Georgian College award. We heard very able and thorough submissions fi.om counsel on a number of issues. We were asked to determine whether Article 11.1 of the collective agreement provided for part-time service to be taken into account when determining vacation entitlements, and as a subsidiary point whether the Georgian College deCision was wrong. If we found that there was any ambiguity in Article 11. l's use of the term "continuous service", we were asked to determine whether past practice should be used to resolve that ambiguity in favour of the College. We were also asked, if we found the Union's interpretation to be correct, to determine whether in any and all of the circumstances of this. case the Union should be estopped from asserting its position until after the next round of negotiations. For the sake of brevity, we will not summarize the positions of the parties but will deal with the arguments in the course of rendering our decision. 12 In addition to Article 14.3, which has been reproduced above, the parties also referred us to the following provisions in the collective agreement: 1.1 Exclusive Bargaining Agent The Union is recognized as the exclusive bargaining agent for all Support Staff employees of the Colleges, save and except: - persons regularly employed for twenty-four (24) hours per week or less and persons employed temporarily during the College vacation periods; 11.1 Entitlement Effective June 30, 1991, employees on the active payroll of the College who have completed the years of continuous service specified, as of June 30t~, shall be granted vacation with pay as follows: 1-6 years: 15 working days 7 years 17 working days 24 years: 29 working days 25 or more: 30 working days 11.2 Calculation of Continuous Service In determining the period of continuous service of employees on the active payroll for the purpose of vacation entitlement: - an employee's previous.uninterrupted service with the College immediately prior to and consecutive with its establishment as a College of Applied Arts and Technology shall be included; - an employee Who, for any reason, has less than twelve (12) full months of active employment during the one (1) year period immediately prior to June 30, inany year, shall receive a lesser vacation with pay on a pro rata basis under the schedule of vacation set out in this Article, subject to any. accumulation of service under Article 14.2. Active employment means actual attendance at the work place and the performance of work,. but includes absence from work for vacations and holidays, or illness for up to six (6) months, or during.pregnancy or parental leave or developmental leave. 14.2 Accumulating Seniority Seniority and service shall accumulate for all purposes under the Collective Agreement for a period of up to, but not to exceed, six (6) calendar months during the term of this Agreement dUring any leave(s) of absence granted, with or without pay, pursuant to 'the provisions of this 13 Agreement. Notwithstanding the foregoing, seniority and service shall accumulate for up to thirty-five (35) weeks in the case of combined pregnancy and parental leave, and during the length of developmental leave and during the first twelve (12) months of absence on Workers' Compensation and for any period of layoff pursuant to the Less Than 12 Month Positions Letter of Agreement. This provision shall not apply in the case of probationary employees who shall be required to complete six (6) months of active employment to attain seniority unless waived by the College. It is understood that seniority and service do not accumulate during the periods of layoff under Article 15. 14.5 Proration of Part-Time Service for Probation Where a part-time employee is hired by the College into a full-time position in the bargaining unit, which is either the same position or, is sufficiently similar in nature, he/she shall be credited with service towards completion of the probationary period, based on a proration of the hours of the part-time position to the hours of the full-time position using 1820 hours per year as constituting the hours of the full-time position, to a maximum period of credit of three (3) months service towards the completion of the probationary period, and provided such service occurred within one (1) year of the date of hiring into the bargaining unit. APPENDIX B INCLUSION PROCEDURES The following conditions are applicable to persons who are employed by a College of Applied · Arts and Technology (hereinafter called "the College") in positions designated as Administrative Staff or otherwise excluded from the Support Staff Bargaining Unit and who are found to be bargaining unit employees as a result of specific decisions of the Ontario Labour Relations Board or by agreement of the Council/College and the Union: 5. Seniority Employees will be accorded full seniority based on length of service with a College calculated in accordance with Articles 14.1 and 14.2. 6. Vacation (a) Employees will retain vacation entitlement earned as Administrative Staff Or an otherwise excluded employee for the Vacation year in which the date of inclusion occurs and one (1) additional vacation year and vacation pay shall be in accordance with Articles 11.2, 11.3 and'l 1.4. (b) Effective June 30th of the vacation year thereafter and of each subsequent vacation year, there will be a reduction in vacation entitlement of one (1) day until such vacation entitlement coincides with the entitlement under the effective 14 Collective Agreement for CAAT Support Staff and vacation pay shall be in accordance with Articles 11.2, 11.3 and 11.4. (c) For the purpose of calculating an employee's vacation entitlement under Article 11, it is agreed that the employee will receive credit for one hundred per cent (100%) of his/her continuous service in the College.

'In reaching our decision we have considered only the evidence presented to us, the collective agreement, the submissions of counsel and the authorities cited. In addition we have held an executive session where we discussed how to deal with this matter. The relevant langUage in Article 11.1 has already been interpreted by Arbitrator Schiff in Georgian College, where "continUOus service" was found to include previous part-time service outside the bargaining unit. Therefore, we are not in the position of a board of arbitration lOoking at language for the first time. It may well be that we could reach a different conclusion on the interpretation of Article 11.1; however, in our view it is not necessary.for us to consider whether Arbitrator Schiff's interpretation was clearly wrong or was correct. There is no doubt that the College's consistent practice here has been to interpret "continuous service" as not including previous part-time service for the purpose of calculating vacation entitlement under Article 11.1. 16 Two members of the local executive were both former part-time employees who transferred into the bargaining unit. On the occasion of their transfer it was made known to them that the College was not crediting them with any past service in calculating their vacation entitlements. Shortly after joining the bargaining unit both of those employees became members of the local executive. Thus, as early as 1989 there was a member of the local'Union executive who had direct and recent knowledge of how the College was interpreting "continuous service" under Article 11.1 for the purposes of vacation entitlement. Neither jensen nor Johnston testified in these proceedings; therefore, it is reasonable to conclude, that they had actual knowledge of the College's practice. In early 1996 when the College began to adjust seniority dates the local Union specifically asked the College if it was going t° adjust vacation credits as well as seniority. The College said no. In the words of Wallace, the College "denied our request". Both Jensen and Johnston were present at the meetings where the adjustments were discussed. The Union did nothing following that meeting to pursue any claim for vacation credits based on previous part-time service. The Union jointly signed the letter to all employees which only indicated that seniority was being adjusted. In view of the specific knowledge which at least two members of the local executive had regarding the College's practice, and in view of the discussions about vacation' entitlement which occurred, the Union must be taken to have known what the College's practice was and to have known that it was not going to adjust vacation entitlements along with seniority. In the face of this knowledge the Union did nothing locally to grieve the College's action or to make it an issue for central bargaining. From all of the foregoing it is our conclusion that it is fair to infer and find as a fact that the Union either acquiesced in'the College's interpretation or led the College to believe that it so acquiesced. As a result the College reasonably took the Union's failure 17 to act at face value and did nothing to try to protect itself from any increased claims for vacation entitlement. This case is significantly different from Georgian College because there there was no evidence of any such local knowledge of the employer's position, and the parties had not specifically discussed the issUe a year prior to the grievance being launched. The only evidence regarding · estoppel which was heard by that board appears to have been the evidence concerning negotiating history. We believe that in the case before us thc College has made out a case for estoppel. We find that this case fits squarely within Chairman Weiler's remarks in City of Penticton at pages 320 and 321:. But a collective bargaining relationship is quite a different animal. The union and the employer deal with each other for years and years through successive agreements and renewals. They must deal with a wide variety of problems arising On a day-to-day basis across the entire spectrum of employment conditions in the workplace; and often under quite general and ambiguous contract language. By and large, it is the employer which takes the initiative in making operational decisions within the framework of the collective agreement. If the union leadership does not like certain management actions, then it will object to them and will carry a grievance forward about the matter. The other side of that coin is that if management does take action, and the union officials are fully aware of it, and no objection is forthcoming, then the only reasonable inference the employer can draw is that'its position is acceptable. Suppose. the employer commits itself on that assumption. But the union later on takes a second look and feels that it might have a good argument under the collective agreement, and the union now asks the arbitrator to enforce its strict legal rights for events that have already occurred. It is apparent on its face that it would be inequitable and unfair to permit such a sudden reversal.to the detriment of the other side. In the words of the Board in'District of Burnaby ... "It is hard to imagine a better recipe for eroding the atmosphere of trust and co- operation which is required for good labour management relations, ultimately breeding industrial unrest in the relationship -- all contrary to the objectives of the Labour Code":' see also the observations of Mr. Justice Hutcheon in Larson et al. v. MacMillan Bloedel (~llberni) Ltd ... To remm to the metaphor which was used earlier, its is equally unacceptable to watch someone go out on the end of the limb, as it is to invite that person out on the limb -- before sawing it off. 18 To avoid any misconception about that conclusion, let me immediately add these two caveats. I am assuming in this analysis that responsible union officials are aware of what the employer in fact is doing. In my view, there is no obligation on the part of the union to take affh'mative action to find out how the employer is actually administering the collective agreement -- e.g., how it is applying the different monetary provisions in the contract to produce a final figure in the employees' pay-cheques .... In this case, suppose the union officials had not been aware that the employer had failed to put additional insurance coverage into effect. The union would not have been estopped from enforcing its contract Position. When Sieg died, the union awakened to the problem and it advanced its arguments under the collective agreement. But in a case such as this one, when the union does know how the employer has interpreted and applied a contract provision, then it is under an obligation to make its objections known within a reasonable period, in order to alert the employer to the risks, in its own course of action. In this case, the union did not object. Then, for the reasons stated above, if the employer can show that it went ahead and acted in reliance on this 'acquiescence by the union, the union is estopped from making its objection and pursuing its grievance expostfacto. In our view that describes the situation before us. Responsible local Union officials knew of the College's interpretation and application of the collective agreement and did nothing to alert the College to the fact that it did not agree with the interpretation and application. If it had an objection, then the local Union was under an obligation to notify the College of that objection within a reasonable period of time so that the College could take steps to protect itself. The local Union's silence allows the College to conclude that there has been acquiescence in its position. The College then cannot be penalized for continuing to act in accordance with its original interpretation and the Union is estopped from bringing the grievance forward ex post facto. For all of the reasons set out above, the grievance is dismissed.
