On the one hand, they should have known better than to use netflix communication channels to talk negatively about work/bosses.

On the other hand, it's a REALLY bad look for Netflix to fire employees for chatting negatively about their boss in private messages. The whole "we're radically transparent" sounds like a horrible excuse for someone's ego getting bruised. I guarantee there are hundreds if not thousands of private chats on their slack with employees complaining about coworkers.

I presume they're now combing through every private chat and terminating any employee who said something negative about a coworker? No?
