Man, a lot of you Americans need to unionize. None of this happens at my work and it's precisely because we're unionized and have a contract that specifically says that our employer is bound by strict rules. Granted, we don't get a month paid vacation, but we can't be denied time off, can't be compelled to be on call, can't be forced to work overtime and we have PTO accounts, healthcare and a pension that get paid into on a weekly basis.
