How the fuck is a turnover rate that high acceptable IN ANY FUCKING WORK?
Even if we leave all the "health" and "work-life" problems, even from a structural point of view (aka money which is what sadly the corporations care about), that is a ton of learning hours thrown to the trash can and time that will be needed to improve the newer employees.
That's the corporate structure of America at large now. Work on minimum viable employees, overwork the ones you have, swap in new blood when it doesn't work out.
It took my boss leaving for the corporate heads to finally realize that our job in tech is doing more than what's necessary and doing other departments jobs and NOW they want to try to make counter offers. The entire business structure of America revolves around under paying you so that you have to negotiate and threaten leaving to get better pay, and even then you'll be expected to do more than what's required or be expendable.
I have a story about a COO who though you could you just "hire temps" because he'd rather have us spend hours every week training yet another temp because, spoilers, the temp services don't provide hard workers and the tech industry isn't something you just..."do" than actually spend money on full time employees.
The entire system is rigged so that if you take time off it's a knock against you, if one person is out it forces an entire team to stress, and they run skeleton crews in tech majority of the time until a disaster strikes in which they throw bodies at it until it disappears (for now). The biggest reason that kept me pursuing art and game dev as a personal aside rather than a full time job was knowing I'd be making less than what I make in other tech fields while working harder and longer hours in game dev, all for the "hopes" of a payoff and not losing my job after the game ships.
Turnover to the people at the top means literally nothing, because to them (especially in a high demand field like gaming) there will always be another body they can throw at something to make a minimum viable product. Even if the product is "great" when it comes out, it won't matter because they've already destroyed any framework built over the production of their last product by ditching structure and trained employees for the sake of saving a buck. That's just how it be.
I know a lot of people that work more than 8 hours a day. I don't approve it, but a lot of people have their professional and private lives intertwine with each other. I have my work email setup on my phone and if I have nothing to do or just feel like it, I can login at home and get some extra work done. I don't mind. And in a lot of cases it's by choice. In return, I can sometimes start later or go home earlier without having to sacrifice time off hours. I know this is not the same, but there are a LOT of people that don't have a 9-5 mentality and immediately run out of the office at exactly 5 PM.
To add to this Salary is a scam. Salary is often used to promote "more money" but that typically means that you are then at the mercy of the company and expected to be on call and on the job 24/7 probably making less than you were/would have hourly.
I like doing work outside of my job because I care about my job, I check emails and respond outside because it's easy enough, but that's not what's being discussed here. This is keeping tons of people in offices doing strenuous work at a pace that's inhumane. It's not like clerical or office work. I'm not saying my job or your job is "easy" but there's a big difference between typical jobs and game dev.
That's also ignoring that if anyone DOES leave at 5 they're typically considered "bad employees." More than one occasion someone's work ethic is questioned for "daring" to go home on time.
