My boss is wrong, and an asshole.

Commissioner Gordon said so!

I'd report this workplace to a governmental agency, you have to have at least one day off during the week.

A day off, like a lunch break, depends on the state one is in. Federal law only covers overtime which is anything over 40 hours per week.

Agreed, you do have recourse.

Plus, it'll piss off jerkwad boss when the NLRB comes in and goes through all his files... Followed by the IRS.

A guy in Oregon was working at 2 locations of Subway for straight time both places for up to 40 hours EACH. The franchises were owned by same boss. It made the paper & there was a big stink. The guy cut one of his "jobs" instead of OT. I'm sure there was a mutual understanding before that, though. This situation is different. I hate it when employers have us over a barrel, but at least we have more reasonable labor laws in the U.S., and I have to say due to Union movements early in the last century.

what country do you live in?

1800's America?
