And when I delivered pizza, my manager wasn't allowed to make me work unpaid overtime. But this is America, and something being "not allowed" doesn't mean it isn't happening all the time. The people affected by this most generally cannot afford legal action to defend themselves against this. Or worse, they're unaware that it's illegal to do this.
You don't need to afford legal action to make a FLSA claim; the point about people being unaware of the legal mechanisms available to them (or even the illegality of it) is I think much stronger.
If I was working hourly, I'd pray they make me work unpaid overtime, because when I was ready to hop jobs I'd walk into court with a fat 2x back wages (1x + liquidated damages) [1]. If they retaliate, it's up to 3x back wages.
