The Canadian Union of Postal Workers (CUPW), representing approximately 55,000 Canada Post employees, has called for a nationwide halt to all overtime work, effective immediately, as contract negotiations continue.
In a directive issued late Thursday, CUPW instructed its members to refuse any work beyond eight hours per day or 40 hours per week, marking a significant escalation in the ongoing labour dispute.
Union officials say they are continuing to review the most recent contract proposals presented by Canada Post but remain unsatisfied with key elements of the offer, including wage increases, cost-of-living adjustments, and staffing model concerns.
In response to the overtime ban, Canada Post issued a statement confirming that no national work stoppage or rotating strikes are currently in effect, and postal operations will continue for now. However, the Crown corporation warned of potential delays in mail and parcel delivery as a result of the overtime freeze.
This latest development follows months of contract discussions and increasing tension between CUPW and Canada Post, with the union citing the need for stronger protections, fair compensation, and improved working conditions.
Both sides have reiterated their commitment to finding a resolution, though no firm timeline has been given.
