Jennifer Henson, a 16-year Canada Post employee, is among the workers in Calgary growing concerned as the national strike reaches the two-week mark. The local union says those on the picket line are having to make tough financial decisions.

The impacts of the Canada Post strike are ramping up as other shippers pause their pick-ups to clear growing backlogs.

The union withdrew an unfair labour practice complaint against Canada Post after the company agreed it would not lay off workers during the strike.

Canada Post said the union's new demands are unaffordable and unsustainable, claiming they would cost more than $3 billion over four years at a time when the postal service is struggling financially.

The union representing Canadian postal workers said in a complaint that Canada Post engaged in "a strategy of illegal intimidation" when it laid off hundreds of striking workers.
