Not necessarily. Every production will need mostly non-star workers. If they're all unionized, the stars have little choice but to sign up or work in the few productions that re non-union. Additionally, the Hollywood model is to sign up stars to unions before they're stars. This is further bolstered by the fact that every trade in Hollywood - directors, writers, producers, technicians and handymen - has its own union.
