✔ 最佳答案
I have been a clerk serving in Department of Health, since 8th, May, 2011(,自己改,純粹畀人睇下日期格式), and for eight years until now. Due to a personal health problem, I unwillingly decided to resign my job.
Thank you for offering me a golden opportunity to learn and gain precious experience. I hope my resignation will not cause you much inconvenience.
Thank you for your endless care, please help prepare a working and resignation certificate for me before my last day.
