Create this simple 15 item survey (plus two "essay questions" at the end), distribute it to your employees, and find out where you're strong and where you might need some attention in terms of these research-based "big bang for the buck" management skills. Hint: Ask a peer or someone else in your organization to receive and score the completed surveys, so that your employees don't have to worry about confidentiality.
NOTE: You'll get an awful lot of "management points" when you:
1) show your employees that you value and seek their opinion on how you're doing, and
2) receive that information graciously and non-defensibly, and
3) make efforts to improve based on that information.
