Sub: Salary Increment Request Letter
Respected Human Manager,
I hope you are enjoying well your best health. I just want to throw back some discussions which were held about a half year ago, in between us. As I have completed my probation period successfully with designated targets. In addition, I have made a record number of inquiries from customers end for the company with five matured big deals for the company.
Now I am expecting for salary increment from your end, which would act as a source of motivation for me. Furthermore, you were also promised me that company would make an increment in my salary after completion of probation. In the end, I would be thankful to you regarding the approval of salary increment from your end.
