Experienced non-union talent will not give their work away. That is usually done by newcomers who are trying to make a name for themselves. You wanted some examples of union contractual inequities. Oftentimes, my fees greatly exceed scale and I have no problem getting it. They don't want the paperwork headache.
Simplicity carries the day.
All the middlemen and parasites increase costs. SAG has aminimum eight week usage buyout for local market advertising. If a commercial or radio spot is only going to run for a weekend sale and the client is producing several different spots using the same VO performer for the same sale over the same weekend, it is patently unfair to the producer to charge a minimum eight week usage fee. The talent clearly benefits from additional session fees on spots that will, likely, run for one day before it is replaced by another on which he,the same talent, is used. Many of my colleagues, some of whom are current and former union officers, agree with these and other contract inequities.
