I guess its not just anonymous surveys though is it, its that, plus a low turnover, plus 1-1 feedback sessions and other things I'm probably forgetting. But don't overlook the conclusion where if you read between the lines, more personnel changes are likely as a result of this.

I think your last point is highly unlikely, there is too much light on this for the issues alleged by Madison to be true, and for LMG to do nothing. But the tricky thing is that the full truth about Madison's issues is unlikely to be made public, and equally the full action taken by LMG will not be made public. HR, and employment issues kinda require privacy - this isn't a government or public department, its a private company with responsibilities to employees past & present mandated by law.
