Looks like you don't know how to properly manage your team.

I had a similar argument with a previous manager I had. Careerist dude started on some bullshit management-speak on measuring workers by ass-to-seat-hours while he had no idea I had a management degree from one of the most respected business colleges in my country. Had to rebuke him with Business Management 101.

Of course, this definitely contributed for him pushing me out afterwards, as small minds can't handle being wrong, and he even had the gall of trying and pushing me an unethical assignment. I got out with a nice severance package, and from the grapevine (it's a small community down here after all!) I hear every quarter somebody quits from his team or moves to a different one.

So yeah, bad managers got to career.
