Without discussing the merits of the entire article, I’d just like to say that this makes my head ache:
“When you have a lower-level job, being exceptionally good at it is usually a deterrent to getting promoted,” says Lilit Marcus, author of Save the Assistants: A Guide for Surviving and Thriving in the Workplace. For example, “when you’re such a great assistant that your boss has difficulty functioning without you, it means that he or she will keep you on as an assistant as long as possible and will not consider promoting you out of their service.”
I understand that this is common wisdom… and it is seriously the dumbest thing ever and the reason why almost everybody in management who does this ought to be fired.
If you cannot see why this is a hugely self-defeating strategy in the middle-term, you don’t have any business managing a business, let alone people. You should go back to being a line worker.
