Ksor, when you eventually find yourself in the managerial ranks you will need to handle a wide variety of difficult situations. A few rules that have served me well as a manager are these:
1.) Never ask an employee to do something that you're not willing to do yourself.
2.) Treat your employees like people, not as direct reports.
3.) Your team will follow your lead. You will usually see in their behavior some reflection of your own. If you display integrity, honesty, and trust in your employees, they will often repay you in kind. If you treat them with distrust, belittle them, and intentionally make their work lives miserable, don't be surprised if they drag their feet in completing their work.
4.) NEVER schedule meetings during lunch unless directly ordered by your boss to do so.
5.) Reward good behavior. How you do it is up to you.
6.) Do not share personal information that is communicated to you in confidence, unless there is a clear and present threat to someone's wellbeing.
7.) Don't worry about the plane that you just missed, the meeting that didn't go as planned, or the co-worker that you can't see eye to eye with at the moment. There's always another plane, you can learn from the outcome of the meeting, and you and your co-worker will likely come to a mutual understanding eventually. Patience is the key.
