The first report - a study to be presented at the Academy of Management conference - concerned people who are promoted into management because of their bad leadership. Fortunately that never happens here, where every promotion is based on sound leadership skills, and bad management is unheard of thanks to careful screening, adequate resourcing and generous support.
The second report - see below - refers to a study which identified stupidity in the workplace as a serious health threat (to colleagues, alas, not to the stupid person themself). A number of incidents were cited where abject idiocy in the workplace had brought on heart attacks in otherwise "low-risk" subjects. Again, we're lucky here in that all of our colleagues are drawn from the membership of Mensa, preventing any kind of asinine behaviour.
Perhaps in the salary negotiations, we should be demanding danger pay?
