In my 20+ years of work, I've never been subjected to such a toxic work atmosphere. The CEO firstly has bizarre rules about not having private conversations, he goes into bizarre rages when disparate teams talk to other teams, and at worst, lets a certain individual run wild with rampant bullying. This individual has no authority, yet he treats the entire tech system as his personal fiefdom, has literal tantrums, drops out of and refuses to attend meetings, gaslights others, and rejects any idea from any other technical person. So bad was this person's behaviour, seemingly with the CEO's blessing - that there was no culture and no innovation. Frankly, this was a miserable place to work.
