Dear Mrs.Zhang,
I am sorry inform you of my decision toresign my current position as assistant in this company.
I enjoy working with the people in the office,because they are kind and hardworking.However,after a month's work,I unfortunately find the job is quite far from my expectations.First of all,I could hardly bear the extra work and night shift.Meanwhile,the salary is far from satisfying which cannot support my large family.What is more,I findmy talents are not being made use of.
I am sorry for any inconvenience caused,and I sincerely hope that you approve of my resignation.
Yours sincerely,
Li Ming
