Managers at all levels invent new tasks themselves so that subordinates break down. There will be no teachers soon. Look and see for yourself how many unnecessary ambitions the 'bosses' have. You don't want to work like they said, leave, we'll find new ones, they're worse or better, it doesn't matter, ambition is important. Half of the schools have it. And fish, as you know, rots from the head, and this is management. Educated.
