You said you considered him an actor - the union that is striking does not. That seems pretty obviously relevant.
Does that extend to the gaffers and everyone else who would get fired? I don’t really think you understand the details of this. Hollywood unions have done a very good job of insulating themselves from retaliation after strikes - everyone has to do it so it’s pretty hard to hold striking against anyone. Plus whatever is baked into contracts. Jennings would be striking alone, unprotected. It’s kind of weird that people are holding him to this when the union isn’t.
