In your career, which resignation impressed you the most?

The last time I left my job was unforgettable. The company's treatment is not high. I have been working for several years, and my salary has not increased much. When I offered to leave my job, my boss was still unwilling to convince me in many ways. I even found a colleague who has a good relationship with me to persuade me, but I wouldn't listen. Since I want to resign, I definitely feel that I can't stay any longer, so there is nothing to miss.
