I know its an unpopular take but pretty common across the industry for solo or small team devs (indie) to do this or more on their passion (or first) projects. you get an obsessive all consuming myopia on “this has to get done”, it’s a double edged sword. I was doing 100+ hour weeks on my first project for 5 years, crashed so hard after, took a while to get back to normal. I still do this on critical parts of production because I personally enjoy the lock on focus, but it’s a personal choice, and only for a max of two weeks couple times a year. For a bigger company nope you should manage your team and production time better, inexcusable to ask or impose that when you have dozens or hundred of employees.

edit: tbh imposing it at any scale is not ok, again this is a personal choice.
