Collective bargaining is an option, but in this particular uber-monolithic form, which is in effect the supply-side version of a monopoly (a monopsony) it means the end for everyone involved, either now or later. For Hollywood writers in particular, this "later" moment has arrived. Watch the strike, and how it's failing (and will fail ultimately) and learn. Monolithic structures can't adapt. They're toxic in nature and fail sooner or later, but not before they ruin everyone involved. There are other ways. But that's another story.
