Every discussion of game unions I see here tends to have a lot of people talking about how they are quite happy with their financial compensation at their non-game job, and how they don’t want to unionize because what if it was a shitty union?!?
Also, Hollywood is kind of one of the major bastions of strong unions in the US. There’s a lot of entertainment unions in show business.
(My favorite example: compare the conditions of folks at union 3d animation gigs with the condition of folks in the non-unionized VFX world; better pay and more stable jobs for pretty much the exact same skills.)
