Well said. Two other things that need to be remembered are, sometimes, people either choose not to apply for promotion and are seen as lacking ambition, and some people have been promoted and have later returned to their previous position and they're happy. I remember a man who was a bank teller who was a branch manager, but the branch where he worked was closed and he was told, "Okay, you can either accept a redundancy package or a demotion to casual teller." Even though he went from a good salary with a company car, he said he was happy as he didn't have all the extra responsibilities. The same as a man I knew who was a teacher, who became an Acting Principal, and the end of his term, he said that he preferred to be in the classroom.
I remember, also, the Year Co-Ordinator at my old high school, when I was in Years Eleven and Twelve, said that he was happy as a teacher. Someone asked him about being Head Of Department and he said, "I don't want it. Yes, you get a higher salary, but there's so much more administrative work that you have to do." He didn't get more money as a Year Co-Ordinator, but where a standard teacher had five classes to teach, he had four. And this was a teacher who said that as a parent, he loved the school uniform, but as a teacher, he hated it. The former, because it was easy to clothe his kids for school; the latter, because the school had a strict uniform policy and he hated having to follow it up and that meant having to go around to classes and check. One right-winger questioned his competence, and to that, I say, "It's not a question of competence, but rather a matter of the uniform being an inane thing. And let's not forget this, either. The school's uniform policy was clear cut; you wore your dress uniform most days and your sports uniform on days when you had Sport or PE. And you were not to mix and match. Okay, if you came to school with a note and said that the washing machine had broken down and the only clean items you had to wear that day were a sports uniform top and dress uniform shorts, he'd understand. But some kids used to just like rebelling and pushing the envelope, and it'd be the same kids everyday."
