Earlier quoted context omitted.
managers should be explicit about how an employee's job assignment is going to help develop his or her career That's interesting. I've had a number of managers in my career and never, not even once, has one of them espoused anything resembling such a position. It's always what can the employee do for the company, not what's mutually beneficial.
I've had several managers and mentors at Intel that we're sincerely interested in helping me develop my career. I'm not saying its universal, but I've seen some.
I know that Intel has changed. A lot. But in the early 1980's Andy Grove (as President, before he was CEO) came up to Oregon to speak to the employees. Someone asked him when they were going to have showers for the employees. Andy responded "Intel is a place of employment, nothing more."
That's not easily forgotten, even though Intel did eventually install showers while Andy was still in charge!
Of course good managers care about their reports, regardless of the tone set by top management.
