And, most organizations can't defend themselves on this issue because they don't pay that well. Track the turnover of employees for every manager. Managers who have any significant turnover need to be educated and mentored and, if things don't improve, removed from managing people. Every survey shows that one of the major reasons people leave a firm is because of mistrust, dislike or incompatibility with the immediate manager. While these suggestions are in no particular order, if asked I would put this one first.
Poor managers are the worst enemy of retention that an organization can have.
Reputations spread and can infect many people and can start a negative buzz about working for the company in the marketplace. Finally, always remember that we have now entered a time when the employees are in charge. They can cripple your success and they know exactly how. Today's employees are better educated, more independent, less afraid, more secure and far more entrepreneurial than those of even 10 years ago. This means that HR policies and practices as well as management styles have to radically change.
