Dear Sir,
I am writing with regard to my job vacation for the end of this month since I have some crucial issues. At once, you said my diligency, dedication makes you wonder and when you want you are able to ask for some time off work so I would need this permission so much. I was wondering if you accept my desire and let me go for approximately one week. Generally, one week is enough for my problems however they are so significant and confusion problems for my career. So, during my vacation my friend and your employer Steve will come to my place for temporary period. Indeed, I can say that he is so professional and attentive person at his job so it stands to the reason during this one week you don't feel my absence. In conclusion, I hope you will compromise my situation apparently and for these factors you make permission available for me. Thanks for everything.
Your sincerely,
Qalib Jio
