To chip in my two cents:
I work in television production; not the same as the video game industry, but the entertainment industry non-the-less and there's lots of parallels, and I've been working professionally now for a little under twenty years.
My thoughts are take any reports like the ones we've been seeing with a grain of salt. Aside from the internet's tendency to sensationalize things significantly these days, as someone who's seen employees and contractors come and go for varied reasons and as someone who's seen employees and contractors deal with phenomenal workplace stresses, there's always more than just one side to any story.
What these former employee/contractor articles are saying might indeed be true, but they're not always the entire truth.
The entertainment industry is an extremely aggressive, challenging, and high stress industry to work in simply because it is a high profit industry. Some of the shows my company makes are factual entertainment murder shows, shows that detail real graphic murders. The researchers and visual researchers we have regularly need to research extremely graphic material, interview families of murder victims, deal with convicts, etc. That is very high stress and wears on a person for very basic psychological reasons.
What many of our researchers and visual researchers do to balance this is they do not work exclusively on murder shows, and rotate out to something much simpler on the stress, like a cooking show, for their own mental health. When they do take on a murder show, they know what they're getting into; the kind of content is clearly laid out for them, and they decide to take the job or not. Other coworkers of mine will never touch a murder show because they know that they couldn't handle it. No one thinks less of them for it.
None of them also look to the company to pay any counseling bills or offer services; they're all professionals.
For those of you who are young, still in school or just starting out in the workforce in general, the best advice I can give you is the truth: Life is not fair or easy. There are times where work will be good and balanced, and there's times where it will be insanely stressful with long, awful hours that just go on and on. Hard periods can sometimes last years, but they're not forever. Your own ability to roll with, and ultimately overcome challenges or not, will be a big part of how well you do professionally or not.
Some people can do this extremely well, others not so much. If you can't at the place or industry you're in, then it might truly not be the place or industry for you. I've seen enough people who couldn't handle TV, and they shifted instead to jobs in advertising, teaching, and a whole spectrum of other things.
The exception to this mentality being when something truly illegal is going on. Sexual harassment, discrimination and bullying, etc. should not be tolerated, and should be investigated through the proper legal channels. There are always resources for employees and contractors to branch out to, always someone to talk to and get advice, even if those people and resources are not within the company you're with at the moment.
For this article in particular, it sounds like the kind of project that Mortal Kombat is simply isn't the kind of project for this poor artist.
