I had completed my 6 months in my company. During this time, I made some mistakes which resulted in receiving scolding from my manager. As a result, I now feel insecure about my job. I avoid meeting him in person and he communicates with me only through email or phone calls. Now, I need to ask for my confirmation letter since I have completed my 6 months here. However, I can't approach him directly as he rarely comes to the office nowadays. I have to email him, but since this is my first job, I am unsure about what to write in the email. Can you please help me out?
