And before he was California's governor (and later POTUS), he was head of SAG-AFTRA (the actors' union) and even led them on strike in 1960 to protest how movie actors weren't getting any money when old movies were shown on TV (similar to how in the recent strike the issue was about actors not getting money from streaming). His views on unions were pretty hypocritical to say the least.
He was head of SAG it hadn't yet merged with AFTRA. As leader of SAG he helped break the CSU strike and served as a friendly witness for the House Committee on Unamerican Activities.
