"The key to being able to keep the good employees is not so much the salary you offer them or even the actual work, it is more about how you manage them and how they feel working under you as their manager. "
Personally I don't think there is a key, instead it's a case of all of the above. You can't keep an underpaid employee happy. You can't keep a bored employee happy. You can't keep an employee happy when you don't treat them well. I've left companies for all 3 of these reasons, it only takes one reason.
