This incident is obviously enough in itself; but I have to wonder just how…steady…the managerial habits of someone with this sort of disproportionate response to an irritation that imposed on their authority have been over time.
Dealing with an autistic child is a particularly intense stimulus; but it’s not like management is without its frustrations or its situations where there’s a temptation to just steamroll a subordinate rather than have to deal with the tedious work of actually bringing people round on some issue.
