I am writing to formally announce my resignation from the company, effective June 10, 2014. I am forced to leave this company due to my family interest.
I really appreciate all of your support, guidance and cooperation during my employment. Working for Brian's Gadget has given me priceless experience with a wonderful group of colleagues. I am confident that I will use many of the skills I have learned at Brian's Gadget in future.
If there is something I can do to make smooth handover process, I will be more than happy to help you.
