I was offered a new job and have accepted it I now need to hand in my notice from my current job.

Initially I wanted to send in a scathing attack as they have been nasty to me but thought as a Catholic I should write a lovely one instead but that wouldnāt really be true. I guess a basic and short letter would be best but should I put anything into it really?
Thanks.
