Came up at GDC last year.[1] There's Game Workers Unite, but they haven't accomplished much.[2] The biggest success remains The Animation Guild, IATSE local 839.[3] They represent most of the Hollywood studio animators. Much of what their members do is very similar to what game industry employees do.

But they get overtime. From the IATSE contract with Disney:

"... all time worked in excess of eight (8) hours per day or forty (40) hours per week shall be paid at one and one-half (1½) times the hourly rate provided herein for such employee’s classification. Except as otherwise herein provided: Time worked on the employee’s sixth (6th) workday of the workweek shall be paid at one and one-half (1 ½) times the hourly rate provided herein for such employee’s classification. Time worked on the employee’s seventh (7th) workday of the workweek shall be paid at two (2) times the hourly rate provided herein for such employee’s classification."

"Crunch time" gets very expensive for employers.
