I know I'll be far from the only person who experiences this, but I went for a promotion into a manager role about a year ago and I really regret it. Of course the money is better, but looking after people is such a drag.
I don't mind the expected things like performance reviews, catch-up meetings, etc, but in this position I'm now exposed to the general incompetence of people much more than I used to be.
I used to feel bad asking my manager more than 1 or 2 questions a week on the understanding that I should be able to use my intelligence to answer most queries myself or at least know who to speak to in the business to get said queries resolved. But I'm now saddled with people who have no shame in constantly asking me questions or expecting me to drop my work for last minute meetings or phone calls where they ask multiple questions because they're either too stupid or lazy to at least attempt to find out the answers. Most of them are in their 20s.
I've started to answer their questions in a less direct way now - eg instead of just giving them the answer I give them instructions on how they can find it out for themselves to try to teach a bit of independence. But it generally falls on deaf ears. I'm hesitant to call it out in a critical way, because I suspect they may say they've got an "unsupportive manager" which obviously I don't want.
Feel free to share your experiences of incompetent work colleagues. I'm sure you'll have far worse tales than me and I might feel better about my lot as a result!
