Email drafting - Notice period

I am Lakshmi. I work as an HR executive in a Pharmaceutical Company. Recently, I joined the organization. Now, one employee is ready to leave without working the notice period. My boss wants me to draft a letter stating that he intends to serve the notice period. Can anyone please help me with this?

Address the email to the employee by name, designation, and employee number.
