I'm not in games, but if/when things start to turn, it's far easier for myself and the people around me to just leave for an employer that treats us right than to try to unionize and force the current one to behave. Those are the benefits of having a job that's very much in demand though, not to mention one that can be worked from home and isn't dependent on geography, so the union isn't necessary because the employees already hold enough power. If the employer has a monopoly on your jobs, being able to unionize is a powerful tool in your toolbelt.
