I don't know that anyone cares about this if their supervisor is competent. What I have a problem with is when someone who is incompetent gets their position because they have a worthless degree and then is put in charge of people who know their jobs and then mucks everything up. And this happens a lot these days.
This is not a new phenomenon. In my past life as a corporate employee, I had my best manager and my worst manager in succession some years ago.
The best manager came in, sat us down, and let us know that he knew we knew what we were doing, to keep doing it, and he'd figure it out, making a few tweaks as and where needed. He'd come from a similar department in a newly acquired company in another part of the country, but didn't yet understand the new corporate or local culture. And he knew he didn't know it. As such, he was valued by all and shortly moved to another part of the company.
The worst manager came in, proudly displayed all of his "#1 boss" paraphernalia, and started to tell us how to do our jobs because, of course, he knew better. Never mind that he came from a different part of the corporation, and had no real idea about what we did. Thank goodness he transferred my position to another area that was probably more in line with what I was doing. Sadly, I wasn't the only one moving on or moving out. He finally left the company, although I think it was due to family health problems as much as his arrogance.
I think the first comment in this thread would disagree with you, that person seems to think younger people are all incompetent.
“hen is put in charge of people who know their jobs and then mucks everything up.”
Yes.
In my experience, the older professional and experienced guys push through the idiot and do their job, well, thereby no matter how incompetent the idiot boss is, the job gets done and this makes the idiot boss look good.
