What this tells me is that his manager messed up big time. Nowhere in this text do you outline any efforts of helping Rick become a team player, conveniently fast forwarding to the point where he finally collapsed under the pressure.
I’ve seen similar situations in real life before, and every single time it could be traced back to management burning somebody out because they overly relied on them and the throwing them away when they predictably became burned out. And then you blame him: “He created a cult of dependence”: where was the manager who stopped this from happening?
I hope for you this was a made up story to illustrate a point, but if it wasn’t you really shouldn’t be writing blog posts but have a review of your management structure.
