Bill C-89 recently passed third reading in the Senate, its final hurdle before becoming law. The bill ended the rotating strikes that the Canadian Union of Postal Workers had engaged in for more than a month and sends the labour dispute to third-party, binding arbitration after a specified mediation period. The bill was briefly held up over concerns that it was unconstitutional. The union says Bill C-89 is “a clear violation of workers’ Charter rights.” The Senate was ultimately unpersuaded.
