Workers are legislated back to work in 1987, 1991, and again in 1997.
With Canada's busiest shopping season ahead of Christmas holidays threatened by a weeks-long rotating postal strike, the federal government is pushing emergency legislation to force Canada Post employees back to work.
McAlister says the decline in donations puts a strain on the 1.7 million people the charity helps annually. "Free collective bargaining is a Charter right in this country and it's time the governments respect it", he said. He said the union's legal team will review the legislation.
Bill C-89 passed third reading by a vote of 166 to 43.
New Democrat MPs had voted against a motion to speed up debate on the back-to-work legislation, with many making an elaborate show of walking out of the Commons after voting, raising their fists in salute to postal workers watching from the public gallery.

He criticizes Canada Post for letting it come to this. It was challenged in court and found five years later to be unconstitutional, though Hajdu defends this new bill as taking a different, more "fair and balanced" approach.
Today's move comes as Prime Minister Justin Trudeau told the House of Commons Wednesday that the government is encouraging both sides to reach a deal, but was prepared to act if there is no "significant progress".
"We have provided conciliation officers, appointed mediators and offered voluntary arbitration".
The move came after the NDP pledged their solidarity with the striking postal workers, some of whom had spent the day occupying ministers' offices. The former government did not allow for labour disruption and took pre-emptive action that was harmful to the labour movement, she said.
Hajdu dismissed that notion, saying she believed negotiated agreements are still possible. "We wouldn't come down this road, however, we have exhausted every option".
