What is a final warning letter?

A final formal warning letter is a written notice given to an employee to let them know that their performance or behaviour hasn’t improved after previous warnings. It’s the last step before more serious actions, like suspension or dismissal. The letter clearly outlines what the issues are, what improvements are needed, and what will happen if things don’t get better.

How to use this letter:

check
