Which is just protecting the unions. I had a job that I could work as many hours as Inwanted. I was fine with this. When the labour board said no, my boss limited me to no more than forty hours/week.
This forced me to get another job and work 80 hours week to get by.
Is there more to your story? Were you getting paid time and a half overtime for all of those hours above 40 hours a week? Did your boss limit you to 40 hours because he had been told by his bosses to limit time and a half overtime?
You realize in this case your 80 hours would still get you just 55k a year since this is talking about salaried employees only.
