you seem like the type of manager from whom your 'underlings' (for lack of a better word) know pretty much what to expect, exactly where you stand, etc. That's probably why those who are still working for you 20 years on are still working for you 20 years on, whether or not they like you personally. The ability of a manager/supervisor/CEO to spell out precisely what he wants/expects (AND sticks to it) should not be underestimated.
