I hope this letter finds you well. I am writing this letter to request a possibility of a fortnight off work. As you are aware that I am pursuing my masters degree in development economics from LSE. As part of my degree program, I am required to write a thesis and its submission is due by the end of this month. I am requesting this time off to have undivided attention to my thesis. Unfortunately all my annual leave has been taken up, so naturally any time I am taking off will be unpaid.
