Unpaid overtime for warehouse workers? Definitely, as long as the worker doesn't squawk to L&I! Work your developers 10 hours a day, then guilt trip them to coming in on Sunday? Amazon does this constantly. Tesla, SpaceX and Blue Origin seem to have the same work culture as Amazon, even Microsoft or Adobe have better work cultures.

Take a look through recent articles about Amazon: https://www.qwant.com/?q=amazon overwork employees&t=news&freshness=all
There's a lot to dislike about bigcorps, but the working environment isn't one of them.
With all that said, the reality is that you can't take a single brush and paint companies that have so many employees with it. The experience varies very widely on which part of the company they are in.
I'm sure parts of Microsoft are wonderful to work at. Just like I'm sure parts of Amazon are wonderful to work at (they have numerous awards as well indicating this: #1 by LinkedIn this year, for example). I wish we'd stop taking articles that point out the experiences of a couple people to mean that is the situation at the company. Report the full story, not click-bait articles.
