Every sells "work life balance" and other corporate nonsense, but who should we stay away from and why? Obviously people are afraid to out themselves, so if you feel you can't go into detail, it's still helpful to explain high level what went wrong/stayed toxic i.e. pay, discrimination, CEO, etc.
The PR agency, Inkhouse, is my vote for trying to pay off employees of color to not discuss their traumatic experiences, having employees work 8am-11pm some days, and faking their company culture for a facade for the news.
