I'm in a union. My dad has been a union rep (different union), so I know a bit.

There is no way my colleagues would go out on strike to protect me if I stole anything. And that's absolutely right. Nor would I expect my union to go into bat for me, after anything like that was proven; nor for anything immoral.

Mad.

Unions are there to make sure you're treated fairly, not to shield members from consequences when they act immorally/illegally.
