Memo Format for Leave Without Informing

To: XYZ

This is to inform you that your leave from office/organization without informing higher authorities is a case of your immoral ethics and improper conduct. This will serve as a warning letter to you and as you are on probationary period yet, in your appointment letter in terms and conditions section it is clearly mentioned that on third warning you will be terminated from the job. This is your second warning with the hope that in future you will show responsibility and won’t disappoint the administration/management.

Sincerely,

HR Department.
