Take my boss for example. Been with the bank 20+ years, team has complete turnover every few years. Doesn’t know how to do anything except micromanage, create extra work, and throw around useless spreadsheets. Couldn’t execute a proper idea to save his life, so spends all his time annoying his team with endless meetings and creating busy work that makes no sense.
Sounds like your manager? Chances are they’ll still be here while people who actually contribute are out the door.
