Haha! The first word that occurred to me when I read the title of your article. Thank you for bringing it out of the closet. This is also one of the reasons you won’t get honest negative reviews on GlassDoor or anywhere else. I’ve known VPs who’ve read the GlassDoor reviews in team meetings with managers and tried to guess the identity of the employees based on language, incidents referred to, department, tenure and location.
Of course there were noooo reprisals. At least, not obvious ones. But thanks to the honesty of some of the managers who warned others non-specifically, everyone quickly knew what was going on. Negative ratings stopped appearing, notch up a giant big success for HR!
