This letter will serve as a written warning concerning the performance deficiencies which have been the subject of my ongoing review.
As I mentioned in our conversation recently, your overall work performance is not acceptable. There are several areas I have noticed problems which must be corrected. The first is the increasing amount of time and frequency of personal phone calls. You have been observed receiving as many as twenty (20) phone calls in your working hours. The number and frequency of your calls is totally unacceptable, and must be stopped.
The second problem is your tardiness in returning from the supermarket (wet market). xxxxxxxx (add more issue if you like)
These problems are gradually affecting your overall productivity. Unless improvement occurs you are specifically warned that your service contract maybe terminated.
It is my sincere hope that you will be able to work constructively toward improvement.
Sincerely,
XXXXX (Employer's Name)
I have received the original of this letter.
