He talks about this in the video. In his own experience in his studios he never noticed someone being unfairly pressured to work more than they wanted, and he had colleagues who worked 9 to 5 and who did just fine. He also claims that from people in the industry he spoke to, most people under these situations choose to work overtime because they value their work a lot, and that he doesn't buy into social engineering arguments that people are pressured into doing it because otherwise they'd get fired.
"Never noticed" is doing a lot of work for you there. Making line employees work more to achieve goals that cannot otherwise be reached except by pushing those employees to crunch is what managers are for. Why would an executive or a founder "notice" this? The work's getting done, what else do they care about?
It's possible that iD was well-run when he was there. (And, from what I've anecdotally heard, that's probably true--Todd Hollenshead gets a lot of respect from folks I know!) That doesn't mean other studios are run so well and it doesn't mean that Carmack's anecdotes cancel out, or even meaningfully put into question, those of people not in his rarefied circles. There are a lot of game developers out there and most don't have nearly the funding or the schedule luxuries that iD always did pre-Bethesda, when Carmack was most involved.
well, if he's right then people might just reject the union. if his experience is biased and/or anecdotal, we'll find out the truth. either way, no point in trying to undermine or discredit grassroots unionization efforts.
The article isn’t describing a grassroots unionization effort. The CWA, a large external organization which expects to benefit from the creation of game developer unions, is pumping in an unknown amount of resources and funding.
