[Breaking Bad] Why was Walter White teaching high school?

Its very difficult to believe that someone so accomplished in Chemistry is teaching at a high school. I mean cmon he should be able to get private sector work easy or at least tenure at a respected private university.

It's implied he's a terrible coworker and an even worse boss.

He did get other jobs in the private sector. IIRC he worked in at least three other labs, and was the head of one. In fact, Skylar and Walt moved to Albuquerque because of a new job.

It's not outright stated, but the implication is that he got fired from each one of them. As we only learn later in the series, the more power he has, the worse he gets. As head of a lab or a tenured professor, he would be controlling and abusive, and eventually let go. The high school job was likely the only stable one he found *because* it's demeaning to him and therefore neuters his power-hungry personality.
