The union representing Canada Post workers says an unfair labour practice complaint over the company's layoffs has been resolved.

Negotiations between Canada Post and the union representing its workers appear to be in a deadlock as the two sides remain far apart on wages and other issues.

Tyler McCombs has about 500 pairs of underwear stuck in the mail.The packages are trapped in Canada Post's delivery network as a nationwide strike — which has now dragged on for two weeks — has brought its postal system to a standstill.

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.
