The only time I’d actually consider crazy schedules was if I was the founder with a huge equity stake and a once in a lifetime opportunity that would benefit from a short period of 996.
For average employees? Absolutely not. If someone wants extraordinary hours they need to be providing extraordinary compensation. Pay me a couple million per year and I’ll do it for a while (though not appropriate for everyone). Pay me the same as the other job opportunities? Absolutely no way I’m going to 996.
In my experience, the 996 teams aren’t actually cranking out more work. They’re just working odd hours, doing a little work on the weekends to say they worked the weekend, and they spend a lot of time relaxing at the office because they’re always there.
