Talks are due to resume Tuesday between the Public Service Alliance of Canada (PSAC) and the Canada Revenue Agency (CRA), while 35,000 CRA workers continue to be on strike.

PSAC wrote on Twitter Monday evening that the two sides had been meeting throughout the day and late into the night, without reaching an agreement.

Earlier in the day, the CRA said in a statement that the agency and the union had resumed face-to-face negotiations, “with a view to arriving at a new collective agreement as soon as possible, which is both fair to employees and reasonable to ratepayers”.

The country’s largest federal public sector union announced early Monday morning that it had reached agreements with the government covering more than 120,000 civil servants across the country, ending a 12-day strike.

The tentative agreements came after the Treasury Board, which oversees administration of the federal government, tabled what it described as a “final offer” on Friday.

They include wage increases of 11.5% over four years, with additional compensation of 0.5% for specific groups in the third year of the contracts. The union says compound wage increases total 12.6% over four years.

Workers will also receive a one-time lump sum of $2,500, which is 3.7% more than the salary of the average union member in Treasury Board bargaining units.
