That's not an ask. Specifically, what should he do about this? He's not legally allowed to stop it, so he can't fire someone for it.

I suppose he could say, "Hey, stop that!" And then...

Given the outlined cases, it just seems like picking a fight for no good reason, one that can't legally be won and has almost no financial consequences.

I'd rather people spend their time fighting for things that will make more of a difference rather than burning political capital on this sort of thing.

When you start screaming about a $6k or even 22k part time job that can't legally be prevented, that makes me less likely to listen the next time you start screaming, and that next time you might have an actual point.
