I am fairly new to management and do not have any training in this field. I have 3 employees who I am responsible for. With each of them having their own jobs to be done. If one is off we all pitch together to help one another out to get the jobs done. I usually resume the bulk of the work load when one is off. The problem is that my computer operator is continuing making errors. They are repeatly the same mistakes over and over I have warned her about this problem and even whent to the extremes of giving her 5 days of verbal warning, and informed her that if this matter is not corrected she will receive written warning and if this continues will loose her job. My problem is I know I can not afford to loose this employee, I have spent to much time into training. We are looking at doing a full conversion on our core porcessing system this year also. So if I do fire her I know I will not have a moment or any vacation myself. But if I keep her how do I get my employee to realize she can not continue to be making the same mistakes, without making myself look like I am letting her off the hook?
