People think you can study management in university and then graduate and get a management job. Most managers begin in some technical or professional field and advance to be a senior among professionals, then a group leader then supervisor then manager, etc. Management is full of fads and what you learn in school at any time will go out of fashion later. If you don't have any technical or professional expertise, you're just a pointy-haired boss. People also think that the best technical person or the person who worked the longest should be the next promotion.
Management is a different skill.
It is not just a status that you give someone to reward them, like employee of the month. It is the responsibility to see the big picture and allocate resources to priorities and find what other people need to do the work in the way that gets the best work out of them. A lot of people who are just very good at the work think it is just about bossing people around and telling them how they would do it themselves. Maybe they always had bad bosses, but that is no reason to be another one. I love going to conferences and presenting papers on my research, and giving seminar presentations etc.
