How to apologize to the leader?

-First of all, thank you for your support and encouragement in my work. Your working methods, efficiency and attitude are all worth learning. I have always been proud to work under your guidance.

Regarding the handling of * *, I am young, thoughtless, not calm enough, and my words are inappropriate. If I have disrespect for you, please be generous. Since my starting point is to do a better job, I beg your understanding.

-You are our role model. You have more work experience and more ways to handle things than I do. I am not mature enough. Please don't mind. I will learn more and better ways to deal with things from you in the future. Please give me your advice.

The following one will do.

Dear unit leaders:

Here, I offered to resign from you because of my impulsive behavior at that time, which made you sad and distressed. To this end, I am determined to submit this letter of apology to you, begging you to forgive my impulsiveness and immaturity.

In a word, my impulsive resignation fully exposed my wayward, immature and irrational characteristics. Without a steady working attitude, I can't face some problems and pressures in my work well, so I feel irritable. As the saying goes, "Impulse is the devil". Impulse is stupid and very unacceptable. Now, I have deeply known that I was wrong. To this end, I assure the leaders that from now on, I will do my job well, make efforts to contribute to the unit and work hard for the income-generating development of the unit.
