How to write the application for resignation of the restaurant?

Dear leader: I regret that I submitted my resignation to the unit at this time and wrote this resignation report. I have been here for almost x months. The atmosphere of the unit is like a big family. Colleagues and leaders are very kind to me and have learned a lot here. I really learned a lot in these three months' work. However, I feel that I have made no achievements in my work. I began to think about whether I was suitable for this job. I feel that I have paid too little and can't get such a safe salary, but I yearn for a high salary. On the one hand, I hope to ease the economic pressure of my future life, on the other hand, I hope to find a company closer to home to take care of my parents. I am also very aware that it is a test to resign from the company at this time. The company is recruiting people and is currently developing projects. The preliminary work of the company attaches great importance to the next step. It is also considering the rationality of the unit's future arrangements for various projects, in line with the attitude of being responsible for the unit, and in order not to let the unit make mistakes because of me, I solemnly submit my resignation to the unit. In the current project, I have done the preliminary interface design, but unfortunately I can't participate in the program development. Leaving this unit, leaving these colleagues who share weal and woe, is really reluctant to part with the sincerity and friendliness among colleagues. But I still have to decide to leave. I beg the unit to forgive my departure and terminate the labor contract with the unit. I wish the unit all the best.
