The comment about management being a skill not everyone is born with chimes with me.
My first (and only so far) experience of managing a team was not a happy one. I found I was too nice to them, and too honest to my boss (who just wanted someone to blame directly for the poor performance of that team). I ended up doing loads of work that my team should have been doing because, for example, what can you say when someone is half way out of the door leaving stuff unfinished and says “if I don’t pick my daughter up from school she’ll be left standing there”?
My predecessor had basically lied and evaded when quizzed by the higher manager about basic security and fraud-prevention checks that she should have done, but took ages to do properly. She had handily moved (been promoted) just as a second wave of bad practice was about to become apparent.
I think one of my major failings in career progression is my inability to tell a lie!
Also, the success of a manager depends greatly on the motivation and personalities of the team they are leading – good, self-motivated people are obviously a lot easier to manage than people who work solely to rule, try to evade doing anything unless directly supervised and generally don’t give a toss!
