You don't benefit from it. Having been in a place where positivity is a focus, it's just ignoring any problems or criticism that can't be addressed with a work harder attitude. It forces out anyone not drinking the Kool aid, and those tend to be better employees.
Yeah, but the original message sounded even more like BS. Like surely no one would think its a good idea to post on social media that you are firing your stressed employees to make a 'supportive' workplace. That makes no sense. So yeah, the explanation is bad - but I don't think its untrue. It's just that the original post was a bad idea.
