Although I don't disagree, publicly announcing turnover stats that are far below average kinda blows a giant hole in the "LMG is a toxic hellhole" narrative. I've been in toxic hellholes, and turnover tells the real story.

This also doesn't negate necessarily Madison's statements and there probably have been real issues, but I think this is the part of the video where he said (paraphrased) "don't panic about a rise in intentional turnover." I lead a team about LMG's size, and people often don't realize that you can say and demonstrate your values consistently at this size, and still have someone fuck it up because some people just come to the org with the wrong learned behavior and it's gargantuan to re-program them to a healthy state, and a smaller few are just unsalvageable assholes. See also, the Stanford Prison experiment. It would extremely not blow my mind to learn that a few people or a particular team in LMG are entirely toxic and it was missed, and also that the experience for the vast majority doesn't match with this and they're trying to run an ethical company. My (optimistic) assumption is that the intentional turnover comment is probably going to focus on those that Madison dealt with.

Workers Union could solve it

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.

I've always viewed off-hours events as a sort of shitty way to show you're a "fun company" (tm). For workers who are already expected to put in well above 40 hours per week in a stressful environment asking them to cut further into their free time for work events really isn't very helpful. It's just one more obligation to the company that you are now being pressured to fulfill

My company has those surveys. As far as I know they are anonymous but the problem is any feedback falls on your direct supervisor to fix. The first year they did it a lot of us were honest about it and our boss got absolutely wrecked over it even though he had very little control over the organizational problems we were complaining about so the next one we always just based it off things he had a say in which he's a good boss so the surveys no longer aligned with the company as a whole.

A third issue with anonymous surveys is that barely anyone fills them in. Only a certain type of personality likes these things.
