A site manager's resignation letter

Dear management:
Greetings! I am a member of the **Works Project Department**. I have been working in your company for nearly a year. I am very grateful for your training and care for me, and my colleagues care and help me. I can say that this is my work. The happiest day. I am very hard to work and study in such a good company, and I have encountered such a good leadership. I really want to stay in the project department, but life is always helpless. Just because of a recent emergency in my home, I I have to go back, I don’t know when I can go back to work in the project department. Since ancient times, loyalty and filial piety have been difficult, I have to resign to the company. However, please let the company leaders rest assured that the project completion data has been basically completed and improved, and finally I will do a good job of handing over the information.
I hope that the leadership can give understanding and give a reply as soon as possible, I would be grateful!
Sincerely, the resignation of the resignation: Internet users
