(In all seriousness, you probably just go to their labor board website and fill out a form or something.)
What do I do now? I don't want to do the 53rd hour. Do I say no to the boss? Sure maybe he can't legally do anything punitive, but that doesn't mean he won't. What happens to my relationships at work? What happens when my peers decide to do the 53rd hour of work and so they are seen as more valuable to the company? Do management folks start seeing me as less of a team player?
What if I go to the labor board? Now the company is chastized for asking me to work beyond 53 hours. What does that do for my relationships at work? My reviews? Promotion prospects?
Let's say I move to another job. Word gets around that I'm a litigious sort of guy who goes to the labour board when I'm asked to work more than 52 hours.
Does this law protect me in a practical way? Is enforcing this law possible in a practical way, which does not cause other problems for the employee?
