Several years ago, I had to replace a receptionist for my unit. Before I advertised for the position, I was approached by another manager, and asked if l would consider a transfer from his staff instead of opening a new competition. My natural question was to ask who he wanted me to consider and why.

It appeared from his description of this employee, Maria, that she was having a lot of problems performing her duties, and had difficulties with her boss, and did not appear to respond to any attempts he, the manager, had made to settle the issues. Now, after listening to his explanation, I really had severe doubts. What crossed my mind, after this discussion, was that he wanted me to take a problem off his hands.

I told him I would think about it and would let him know the next day. As promised, after thinking more about this potential performance issue, I decided that I would agree to speak with Maria privately before I made any decision.

And, what I found out during this interview, left me deep in thought. As it turned out, the    performance issue appeared to result from working for a boss who never extended a good morning greeting, never gave a word of encouragement, and was constantly changing the work load and routines. The end result was a totally ruined employee who was unconfident, hated to see a new work day start.

I decided to accept her transfer to my unit. What started out as a shy, withdrawn and frightened employee turned out to be one of the most productive and loyal employee that I had ever worked with. Maria couldn't do enough and was constantly asking for more and for more responsibility. I was more than happy to give her what she needed-praise for work well done, respect as a person, and encouragement for doing well in anything she dealt with.

Sometimes, we are guilty of holding others back from accomplishing or doing or developing as they should or could. It may be a wise idea that we all look in the mirror, from time to time, to see what we are really like.
