The unions guarantee a minimum price floor for actors, and healthcare if you work full time. No maximums.

Unfortunately the entire reason for the strike is studios will rarely, unless you are very top talent, deviate from the minimums. They would often try to go even lower, if they could. Hence the strike is to raise the minimums.

There’s 160,000 members of SAG. There’s maybe only 50 household-name celebrities acting in any one year? Those 50 are not representative of everyone who acts at all.
