I can't speak for this situation, but I was involved in situations with corporate crime at high levels. People were very cognizant of what was in email and what was verbal.
When I considered whistleblowing -- what started as little spiraled out of control -- and looked over evidence, there was very little.
One attorney at the company was fired for putting the wrong thing in writing.
Interesting. The lawsuit only has a couple of screenshots of emails which relate to one manager, but no screenshots of emails which relate to the wider organisational allegations.
The factual allegations in the lawsuit mention several times that management asked people to delete emails that related to the policies and targets. This might mean that there's no proof of these emails any more, or it might mean that the allegations are false. I think in these cases, the plaintiff has to prove things.
