Hi,
Dear Sir,
With due respect, I would like to bring to your attention the subject of an increment tomy salary.
As you are aware, I have been working in this company for 3 years and I am getting a very low salary. My daily living cost is increasing, and I am facing great difficulty in meeting my family expenses. In addition, I got married one year ago.
You know that I am working in the company with my best efforts, as hard and sincerely as I can.
Thank you very much for your kind consideration.
Sincerely,
Good luck, Clive
