Good point, that makes sense. It happens to be a special case, so they’re saying it here. But in general very few will probably be saying “this place sucks” about their employer.

Good (or at least smart) employers pay quite a lot of money on quarterly anonymised surveys precisely to hear what their employees truly think about the company. I think some shareholders care about those numbers as well enough to want to see them. Of course there is a difference between saying what is obvious to anyone interested anyway (like above) and crying publicly over some petty grievance.

Besides, if the company only seeks spineless lackeys would you want to work there anyway?
