Dear Mr. Adam Jane,
I am writing this letter to demand a short break from my teaching courses in your institute.
In the last few days, I was not comfortable while I was teaching. I think that I am under pressure since my wedding will be in the next 20 days as I informed you in our last meeting. Therefore, the arrangement should be taken soon such as cards invitations. Moreover, I have been working without any vacation for almost a year which may affect my performance in the class.
I would like to ask you for extra 10 days due to my family have booked a covered holiday in Tunisia just the day after my wedding. I would be most grateful if you could make them at the beginning of May.
I talked with my colleague Mr. Walid Radj and he said that he would replace me during the Mondays that I teach the CA class. Furthermore, I have prepared for the student all the courses they need in this period.
thank you for taking the time to look at my matter. I am looking forward to hearing from you.
Yours Sincerely,
