Thanks for the link. That was very helpful. I'll provide a short summary of what I read (not full article) since it's a big article. Lots of people are doing the suing:

- People used racist language and wrote that stuff places

- Immediate action was taken but then effectively rescinded (a guy was fired for being racist but brought back in a non-supervisory role)

- 'Soft' retaliation occurred: they were forgiving of people making errors but if you had previously complained, then one mistake would end up with you being fired

- Race-based task discrimination is claimed: Black employees cleaned while White and Hispanic employees took a rest break

At that point I stopped reading, since that was good enough for me to know that it is definitely more than I initially thought.
