Sorry, I know I hardly ever post but need quick advice as I promised I'd do this before H got home for him. :)
"Dear *
Please accept this letter as notice of my resignation with immediate effect.
Many Thanks
*"
it's for DH to hand in tomorrow. He's jumping before pushed and they are a bunch of arseholes hence the no "thanks for the experoence, it's been a pleasure blah de blah".
