Why not just stay SAG and do non-union work anyway?
Two reasons: 1. it is dishonest. When your child joined SAG you (and they) promised that you would honor SAG Rule One and not do union work. You signed a document to that effect. Doing non-union work sends a poor message to our kids about keeping promises, and 2. Since your child is a SAG member, they are opening themselves up to severe discipline within the union if they do non-union work. SAG takes this very seriously (even with kids), and gets tips on non-union workers from other cast members, crew who are union, call sheets, photos, etc. The normal process is that SAGs legal department will send you a letter demanding that you explain yourself, fill out a form, etc. Then you go to a trial hearing before the Discipline Review Committee at SAG. Often the penalty for doing non-union work is a significant fine, suspension or termination from membership. Is it worth it?
