Oh I've known from back my food service days that "management" aka salary was a fucking scam.

It was ALWAYS a way to get massive unpaid overtime extracted upon threat of firing. And overtime for workers was inexcusable, no matter what. Got a rush? Too fucking bad, clock out.

These days professionally, I agreed to 40h/week. That's what they get. If there's a real outage or un-manufactured crisis, then I'll stick around. But its comp time for the week.

I don't work for free for capitalists. If they want more labor, they can pay for more.
