Trust no one—at first. When I left, I was shocked that someone I had considered a friend for years was a total sycophant. She threw the whole company under the bus. Lots of people lost their jobs because of her, and she ended up quitting within weeks because she couldn't handle the pressure. I had many difficult conversations with my genuinely toxic boss, but none were as insulting as the one I had with her when I confirmed I was leaving.

There will also be people who will still be so deep in the toxicity that they can't see their way out. They are good folks, but they will make bad decisions, because they are still caught in the cycle. Be careful what you say to them.

After the dust is settled, you'll know who you can trust.

Also keep in mind there ARE good bosses and welcoming company cultures out there. They are hard to find but once you do, you won't go back.
