"Technically" being paid for? There is absolutely no reason for anyone to do any commercial work unless being paid for. People are not slaves, they have their own lives and their own free time to do the stuff they want to do. To expect from anyone to work for free and complain when they refuse to is outrageous.

> I'm not saying anyone should work for free, but sometimes you have to help out, whether it's working a bit later or helping during a crunch time.

Yes, in fact that's exactly what you're saying--people should work for free. You're just calling it "helping out". The employee is not there to "help" you (do what? get rich?), they are there to do the job they're contractually being paid to do. If you need more work to be done, then arrange so. If you need free "helping out" feel free to call in your friends and family.
