Because they have a different contract for work not covered by the current strike? That seems kind of a weird take, especially since they thought the strike did apply to them originally and they shut down for several weeks until the lawyers got together and said, oh no, you have a different type of agreement.

It's not like they changed or updated their contract to become exempt. SAG just went, oh, your business doesn't fall into the terms of the strike so you don't have to strike with the rest of us.
