At the opening of this round of negotiations, the Government made it clear to all negotiators that retroactivity and implementation of the agreements are key issues, given the ongoing challenges related to the Phoenix wage system and the implementation of the agreements reached in the previous round of negotiations. Through the working group, TBS and PSPC examined different options for the retroactive processing of payments as well as the implementation of the monetary components of collective agreements as a whole. This Mou aims to implement the agreement between the employer and the Public Services Alliance of Canada (PSA) on the process of reopening collective agreements for the following collective units: given the current wage and personnel systems and persistent wage management challenges, the Canadian government does not have the flexibility to implement agreements on a basis other than what is contained in negotiated tariff units.
