One nice thing about being in a union is that if my upper management ever got a twinkle in their eye about this kind of thing (they wouldn't, because they're cool), I'm 100% sure I could flat out tell them no, AND keep my job.

If I wasn't in a union, I'd like to think I'm personally in a position where I could still tell them no and deal with the consequences. But I know a lot of people won't be in that position.
