dear ，
re:resignation from the pos to settlement clerk
i would like to let you know how much i have enjoyed my last three years at the hero company。hero company is an invaluable place for enriching my knowledge about financial field，i enjoyed working with my colleagues and i have learned so much things here。
because i would like to take a new challenge and i want to meet people from all walks of life， i have accepted an offer from an insurance firm as a personal financial consultant。 i would therefore appreciate it if you would accept my resignation effective from 8 march， 2010。
i would be very much obliged if you would kindly give me a reference letter before i leave。 thank you for all that you have done to make my work here both interesting and enjoyable。
yours sincerely，
alexander fung
