I worked in the video game industry for several years.
Being "in the red" over dues wouldn't be on by top-100 list of things to care about.
The regularly use worker hostile behavior - Two famous examples are eternal crunch times and laying off entire teams after shipping a game, even after luring them from other companies with promises they wouldn't.
Eventually, I left that industry entirely, which was unfortunate. I loved what I was making, but I hated what they could get away with doing to the workers.
It reminded me of Hollywood - So many young actors wanted the job, they knew they could mistreat them, and regularly did.
A union would be excellent here. Don't get caught up on the money part.
