I want to extend my horizons.
I have made a tuff decision, sir, here is my resignation.
I really enjoyed working with you, however, I think it’s about time for me to leave.
I wish to get into the advertising business.
I see no chance of advancement.
I love the position with the desire of improving my position.
I found a full-time job after graduation.
The job is out of my major.
I’ve been trying but I don’t think I am up to this job.
I want to do a job that can Offer me the opportunity for advancement.
I have been here for too long, I want to change my environment.
I am sorry to bring up my resignation at this moment but I have decided to study aboard.
To be honest, I got a better offer.
I am running out of steam, I need to take a break.
I am quitting because I want to try something different.
I am sorry to see you go.
The office will not be the same without you.
My former company has been bankrupt.
Because that company didn’t have a good future, I needed to consider my future.
