> Very few managers are good leaders.
I saw (a black & white hand-drawn version of) this image [0] a while back and found it a really effective visual to easily explain the difference between a boss and a leader. (Here's an article that expounds on the topic and has some variants of the preceding image. [1]) I've worked with/for both types and the first type (boss) simply does not inspire loyalty or any interest in "going above and beyond" the bare minimum of absolutely required work from their employees.
The genuine leader type on the other hand often didn't even have to ask employees to put in any extra effort toward their job. Folks just generally went out of their way to try very hard to do their very best work (or damned close to it) for the true leader-type because it wasn't uncommon to see the "leader" right there "in the trenches" with them "getting his hands dirty doin' the work" right alongside them, and it just didn't feel right to not put forth at least the same effort he was.
I think (at least to my mind) the difference (in employee attitudes) is one of respect (leader) vs fear (boss).
