I also concluded that doing meaningless administrative/management work is addictive and those who engage in it will actively and constantly try not only to overemphasise their importance but also force themselves on top of those who they know are doing actual important work. This is in my opinion a form of understated and poorly understood violence, but also a natural survival instinct for those who feel themselves useless (maybe correctly) and must then fight to remain relevant at all costs.
Sorry for those 1% of you out there who are actually useful and efficient leaders/managers; you know who you are and this is not for you.
