The union filed a policy grievance arguing that the employer was estopped from changing its practice regarding pension contributions for full-time employees on short, unpaid, non-statutory leaves.
Previously, employees paid only their portion of the contribution, but following a correction by OMERS, employees were required to pay both their own and the employer's contribution to buy back service.
The Grievance Settlement Board dismissed the grievance, finding that the union failed to establish the criteria for estoppel.
The board noted that the collective agreement did not address the issue, the employer's past practice was an administrative error based on a misunderstanding of the OMERS plan, and the new rule was not unconscionable as employees could opt out of buying back service.
