Request a salary adjustment after suggesting a new idea or improvement that adds value to the company.
Dear [Manager Name],
As I approach my second year in the job [Change the duration according to your situation], I find myself more dedicated, more devoted and more motivated than I ever was. I am in constant peruse of ways and methods to translate this dedication by improving the quality of our work. My latest contribution does not fall short of my goal to achieve best results in my work. [Here talk about the idea you came out with and elaborate about it and how it helps the company].
I am confident that you agree that I am adding value to this company by continuously suggesting new and effective ideas. In this context, I would like to kindly request you to consider a salary adjustment that corresponds with the contribution I am giving back. Such an adjustment would resemble the utmost acknowledgment to my efforts and never ending dedication.
Thank you.
Sincerely,
[Your name]
