Utilize a warning letter when it is needed.

employee performance warning letter

Employees can sometimes behave very badly that you have to stop them and give them a firm warning that has expectations and consequences. A warning letter helps the employee identify the implications of underperforming and safeguards them from dismissal. A verbal warning precedes a written notice. If the staff does not perform better but continues to be unproductive, he is served with a written notice that is filed in his personal file. A warning letter is not anything to be happy about as it puts you in the limelight. An alert message must be specifically written to address the problem at hand and ensure the employee understands it.

You are at this moment warned that failure to improve on your work performance would invoke a more serious action from the company directors. You are also advised that any repetition of such poor performance will be dealt with severely.
