8th february , XX
dear mr. wong,
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, XX.
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
