Well put it this way : nobody working at BA is going to come on PC to participate in threads where people are discussing former BA staff complaints about the BA work environment and the CEO.
If you wanted to design a special kind of kryptonite to repel all current staff from the boards, that's probably it.
I see your point, but not convinced.
Plenty of times I've been involved on threads where other people are discussing things that I would never have commented on: just because other people are slinging mud around doesn't mean it sticks to you (unless you throw back etc)
I think it's more important to discuss the fact that Glassdoor is hardly a great yardstick - The people most likely to post a review are the ones that felt slighted. If Big Ant have only produced a handful of those in like the 10 years that it has been "a thing" then that's not bad going tbh.
Before we start to not talk about it, let's challenge the validity of it a little - I'm always wary of these sort of sites where you can anonymously gripe.
