Would likely be 100 if you remove all factors keeping somebody from quitting a job.
Only if all bosses are bad :).
After graduation the quality of managers varied greatly. There was a guy with 20 yeas experience, who took my mentoring very seriously. He fired me when I started my own company. Good decision actually! A boss before him was a great narcissist, if I were smarter, I would be able to play him and got higher. Not really the one to run from. Then there was a bunch of old dudes (totally incompetent) building big corp’s first electronics. They had no experience in the field and were really annoying. I quit. There was small company later with whole family in management: 2 sons, dad and mom. And a 2nd engineer. It was a part time position, so I was able to stay and suffer. No chance to stay with them for a 5 day workweek. My current manager is very restrictive. I can do things only old good way, all cost saving efforts and innovations are not needed. Heck, I could save company my early salary dozen times, but all the ideas were rejected.
