You have been counseled and warned of deficiencies in your job performance (please see notification dated ________, 20 __, a copy of which is attached).
Regretfully, the deficiencies do not seem to have been corrected. Immediate action, in conformity with the earlier notification mentioned above, must be taken by you to correct your performance deficiencies. I cannot stress too strongly that such action must be undertaken without delay. Failure to comply will result in your dismissal without additional notice.
I have attached a copy of this notice; please sign where indicated and return the copy to me promptly.
