Our PI is renewed for being one of the worst in the planet, but he's also a really famous one. (average is 1 science + 1 nature / year)

Is hard to find someone this bad, but the worst part was not the micromanagement. That is pretty common. It was the constant lack of appreciation, being blackmailed over the visas, his holding papers hostage for years until your loyalty was proven. A colleague has been there for 4 years of post-doc, and has 0 papers published, 6 ready to go on his desk. And the first one is from 3 years ago.

I can go on all day over this.

I resigned yesterday at the second post-doc.
