Just started a new job, in California if it matters. The expectation is to work unpaid overtime off the clock, and you get written up for clocking in even a minute over 8 hours, but the expectation is to just keep working anyway. It's a really short term temp to hire, so I'm considering sticking it out that long and then just reporting them to the CA labor board, because fuck 'em. If I do, is there any way for me to prove I was working off the clock? Is there anything I should do now, to make the best case possible?
