I once had a boss who would write emails to us as if we were clients, not colleagues, with a completely formal style.
Internal emails should match internal conversations - not completely blunt, but not sounding like a job application letter, either.
Displaying favoritism is another sign of a bad boss; it kills morale (perhaps more than a boss who yells at everyone equally).
For example, there are positions where yelling loudly is imperative. For example, do you want the manager of a construction site to quietly state that a beam looks unstable?
There are also jobs where sickness is common even if you're the best boss in the world. Kindergarten teachers get sick because children are icky, germ-ridden little things, not because their boss is a jerk.
I think measuring inappropriate things is one of the biggest problems with bad management. It's the best way to ensure that your employees are either mediocre or pathological.
However, it's not a sign of bad management. That list is literally meant to be a list of things you can notice about the place you're managing and say, "Holy cow, these are warning signs! I should examine the situation closely." If the manager knows his benchmarks are broken beyond use but persists in using them, he likely doesn't care about anything in this article.
Adding a person who makes sure other people work to a team can be one of the most retarded things ever to a profession where creativity and excitement keeps people in the career to begin with.
