* Unfair treatment: many are driven by mission to the point where they willing to tolerate a lot, which they need to do. Until recently, there were people who were always on renewing 3-month contracts, giving them the feeling that they can be fired anytime. There was a support engineer who didn't get paid for months of work and had to get back pay.
* Entangled relationships: there have been a lot of people who have dated each other openly before, then dating other co-workers. Sexual abuse scandals, and to a lesser degree, social entanglement, often causes people to pick sides and makes it difficult to maintain a professional environment.
* Values over productivity: there are some employees that refuse to use voice or video, causing all meetings to be through internet relay chat. Slack isn't even used, because the company does not like having a company know what is being said. While I understand that this anonymity tool needs more cover, it was incredibly frustrating to coordinate with others though essentially an AIM chat room.
