The Canadian Union of Postal Workers has given 72-hour strike notice to Canada Post.

The notice is for both the union’s urban and rural and suburban bargaining units.

In a release early Tuesday morning, the union says workers will be in a legal strike position as of Friday if negotiated settlements have not been reached.

However, the union says its national executive board has yet to decide if a job action will happen at the deadline, saying that will depend on Canada Post’s actions at the bargaining table in the coming days.
