Dear Sir or Madam,
I am writing this letter to inform you that I am going to study a three-week course which will be held in the next month. This course will be held on even days from 2 pm to 6 pm. So, I need to leave my work on these days at 1:30 pm instead of 4 pm. During this course, a well-known engineer in my field will teach the participants up-to-date procedures to be more effective both in teamwork and problem-solving. I will use this knowledge in my profession as much as I can and it will be my honor if I can teach these procedures to my colleagues.
I would appreciate it if you accept my request. I am waiting for your prompt response.
Yours faithfully,
Hamed
