Being short staffed is the whole point. They believe (where they are right or wrong) AI will replace large number employees. For example in my company where that are pushing vibe coding, my boss said that now they believe that the large projects need less people.

If you use AI and still have to work overtime you are your own problem. As long as you deliver why would they change anything? Don't deliver. It is not worth sacrificing your health for someone's else's profits. You have only one life.

I see people who embraced vibe coding still working overtime and over weekends, more than before.
