Very bad situation, but seems like those employees rather work there than leave to another company or really strike and improve their on condition. lost posts floating in the internet won't be what will help them.

Meh what is 100 hours, how about 200.. oh wait

Sure they could ask that, but that wouldn’t fly in court anyway. A company’s not above the law.

Game developers are disposable, and always have been. It's why I don't make video games any more. 60-80 hour work weeks minimum for months at a time, often times with no extra pay, and a salary that's 20-25% less than what you can get in other software development roles.

"Don't like it? Here's a stack of resumes of people that would happily replace you. What's that? That game you've been working on just shipped and we're gonna have a few months of pre-production before our we need to put a full team on it? Here's your lay off papers with meager severance. You can apply again when we start to re-hire, but if we hire you'll be treated as a new employee with no seniority."

I miss making video games, and I also really, really don't miss making video games.

You can leave for another company but most of them aren't going to treat you any better, and you can strike, but, there's a list of people that will glady take your jobs.

The video game industry is a fucking meat grinder. There's a reason most people last less than 5 years.

Except that it's a common pratice in the video game industry not to pay employee for their overtime. They're paid 40hours/week even when they do 100+.
this link contains some devs that shared their experience with overtime https://www.quora.com/Do-video-game-developers-get-paid-for-overtime
There are tons more if you google it.

Now, I don't know if it's the case at Rockstar. but I know for a fact that a lot of well talented programmer choose not to work in the video game industry because of these conditions. And as a result many studio have given up on recruting talented employee and just hire whowever they can. 

The outrage over this is campletely unwarranted. Reminder, the employees are not slaves, they can quit whenever they want.

They are salaried employees, so they probably make less per hour than working at a gas station. Nobody chooses to work 100 hour workweeks. They are forced to. Why don't they quit and get a different job you say? Well, student loan debt is a hell of a thing, especially for students that went to a respectable game school like Digipen. And there's no other jobs out there these days. The AA industry died out years ago, so all that's left is AAA jobs with insane workweeks, and 100 people applying for that 1 videogame job. 

There is the alternative of trying to make it better for everyone, though.

Following that logic, no one would have complained back in the 19th century, when children worked 16-hour shifts on factories, since they could instead have been at risk of starvation back in the countryside. Or going even further, enslaved africans and natives should not have complained either, since they had clothes and shelter and are no longer pagans doomed to damnation.

It can sound like an extreme example, and I'm not saying you and most people think like that, but everytime I heard that sort of speech, I can't help but think those are exactly the sort of people who would have defended stuff like I mentioned if they had been born two or three centuries ago.

Out of curiousity, what is your profession?

This is very sad.

OP: Practices like these need to be regulated by governments, in my opinion. This is a case in which forming a union makes sense. It's obvious that companys won't change their behaviour out of generosity.
