IATSE isn’t part of the strike. Most likely because AMPTP would find a way to make American Gladiators with non-union labor, which would be a body blow to the union.

If you’re IATSE, you’re working right now, because the union isn’t on strike.

Edit: upon re-re-re-reading your comment, I now think you’re saying that the crew got fucked over, which I wholeheartedly agree with.
