As required by my contract of employment, I hereby give you (insert number) weeks’ notice of my intention to leave my position as (insert job title).
I have decided that it is time to move on and I have accepted a position elsewhere. This was not an easy decision however, I am confident that my new role will help me to move towards some of the goals I have for my career.
I understand that my notice period is (insert number) weeks but I would like to join my new employer at the earliest date. Therefore, I would like to request that you waive this notice period and relieve me of my duties immediately. Please be assured that I will do all I can to assist in the smooth transfer of my responsibilities before leaving.
I wish both you and (name of employer) every good fortune and I would like to thank you for having me as part of your team.
