The original article headline is: "1 in 10 Dead Bosses Are Murdered."
This is a rather crucial difference, to put it rather mildly. You should use the original headline.
corrected. thanks!
My personal experience is that about 20% of bosses (I'm including my boss's bosses) were so often out of line that there were employees hoping to meet these guys in a dark alley. 70% of my bosses were varying degrees of competence/incompetence. And, only about 10% were respected and liked.
Why didn't they give the non-management murder statistic? Or the percentage of fatalities that were in management?
