Huh, well fear is a very different thing than stress. Once your stress turns into fear, you’re no longer personally invested in the project and are merely concerned about your own survival.
The video games industry definitely comes with a lot of stress, but they rely on passion to get value out of those long hours. This sounds like a situation of completely awful management, which won’t be fixed with a union (at least not immediately), since a bad manager can make life suck even if you have decent benefits, reasonable work hours, etc.
Then again, I don’t have a lot of details to go on, just that there’s allegations of “fear” at Daedelic.
