As a manager, you have a choice to be a boss or a buddy to employees. But an employee doesn’t have that choice — you are his boss. When you use the buddy-style approach to management, you blur the lines, says Bernie Erven, professor emeritus at OhioStateUniversity. And that can create problems.

Just look at the dictionary definitions, says Erven.

Friendly — Favorably disposed, not antagonistic, warm, comforting.

Friend — A person you know well and regard with affection and trust.

Buddy — A good friend.

If you are buddies with your employees, they will expect you to cut them some slack. In order to avoid that situation, you must develop a proper employer-employee relationship. Yes, you should be friendly to your employees, but you also must define what you expect from them and what they can expect from you in the workplace.
