Is there a rule in British Columbia about not sharing your salary with your coworkers

The company may frown on it, and people may feel they don’t want you to know s they don’t want to cause trouble of jealously, but as a union employee, and even when I wasn’t, I always felt not sharing your salary was only hurting each other as workers.I’m all for transparency.Once I remember everyone deciding to tell each other what they made except for one guy who had been asked not to by the company.

A few weeks later I found an envelope on the ground and looked at it to see to whom it belonged.It was his cheque.
