CUPW’s Constitutional Challenge Before the CIRB Continues

On March 3^rd and 4^th, the Canadian Union of Postal Workers (CUPW) continued with its constitutional challenge before the Canada Industrial Relations Board (CIRB).

We are challenging the constitutionality of the action taken by Steven MacKinnon, the Minister of Labour, against our union in December 2024. He used his powers under section 107 of the Canada Labour Code – through an order to the CIRB – to bring an end to our lawful, nationwide strike.

Violation of our Rights

In recent past, we have seen the government resort to section 107 of the Canada Labour Code to end or suspend lawful strikes for many bargaining units.

This new iteration of the attacks on our constitutionally protected rights does not allow an opportunity for public debate where the public, unions or political parties can voice their perspective on the issue. We believe that this constitutes an attempt from CPC and the government, who is the sole shareholder of the Crown Corporation, to undermine the role of unions and workers in free collective bargaining. Unions across the country are fighting back against this unfair attack.

Threat to our Collective Bargaining Rights

We believe that constant and repeated interventions from the government in collective bargaining disrupts the sensitive balance of power in the Code and allows employers to stall negotiations awaiting government intervention.
