Question: what is a must join sag?
Answer: You can work three SAG jobs before you have to join after you've become SAG-E. Once you work that third job, you become a must-join. Meaning, you have to join SAG if you book another job. That's when you have to pay the 3 grand. You should just check on the SAG-AFTRA website what your status is so you can keep track.
