I told the CEO that not having a disaster recovery plan was a bad idea. He did not like that. Got written up the next morning. They wouldn't even tell me exactly why I was being written up. Only that I had "not done what I was supposed to" which was apparently to sit there in silence.

Got fired from that job a few years later. My bosses boss called me at home because he didn't have the decency to do it to my face. In that moment I panicked a little but by the next day it was like a weight had been lifted. That place was a complete shit show.
