Dear Mr. Brandon,
My present appointment carries an annual salary of USD18000; this was reviewed in March last year.
During my 5 years with this Company I feel I have carried out my duties conscientiously and have recently acquired additional responsibilities.
I feel that my qualification and the nature of my work justify a higher salary and have already been offered a similar position with another company at a salary of USD20,000 per annum,
My present duties are interesting and I thoroughly enjoy my work. Although I have no wish to leave the Company, I cannot afford to turn down the present offer unless some improvement in my salary can be arranged.
I hope a salary increase will be possible otherwise my only course will be to accept the offer made to me.
Yours sincerely,
