I am on salary, so I don't get overtime unless the company is making 110% of their projected budget for the week. If we aren't, but need to work longer, we basically work for free. When we get "overtime" on salary, it's called "flywheel", and we must work 45 hours first before getting flywheel, which is your hourly rate, no time and a half.
We did have mandatory over time not too long ago, minimum working 6 days a week. We're slammed right now too, but luckily I work quickly enough and manage well enough that I don't have to worry about putting in overtime. Really makes me miss being paid time and a half for it though - would love to be working OT now!
