I hope this is the right site for this question. If not, please direct me to the correct one.
I am looking for help to provide feedback to someone on a letter they have drafted. I have found it tough to search for a comparable format on Google because it overlaps with other kinds of letters.
This letter in context is along these lines: A certain amount of money started as a stipend for something that was not part of the main job description. But over time the responsibility has been effectively added to the main job. So the person wants to request that the stipend be moved over to be part of the main salary since the work is now part of the main job.
When I tried to search for examples or advice on such a letter, I got results about cover letters, asking for raises, expressing salary requirements and so on. But this is not quite those - no raise is being asked for, just a change in how the money is treated.
Aside from the minor grammatical feedback that I tend to give, I would like to review the draft for the bigger picture to make sure the letter is effective and does not include deal-breaker lines that would imperil the request.
