Is it appropriate to resign and call, or is it appropriate to send a text message to WeChat?

1 It is more suitable for resignation and face-to-face communication, or by writing or email. If not, calling to send WeChat is not so formal.

The format of resignation letter is as follows:

Dear company leader xxx:

First of all, I would like to thank the company for its training and long-term care and love, which made me feel at home. In the days with you, I learned a lot of knowledge and learned many principles of dealing with people. But due to personal reasons (family reasons/physical reasons, etc.). ), I can't continue working in the company. After careful consideration, I decided to resign on X, X, and hereby submit my resignation report to the company. I hope you can find the right person to take my place in time.

I am here to convey

welcome
