In accordance with the terms of my contract, I hereby give you two weeks/months notice of my intention to leave.

I would however like to request that you consider waiving the notice period and allowing me to leave at the earlier date of March 28, 2009 immediately.

I have found employment with a new employer and regrettably the start date for that position is April 1, 2009 I do not wish to cause any disruption to the effective running of your organization and will assist with the transfer of duties and responsibilities before leaving.
