Thank you Moz for your reply.
My understanding of the term is the same as yours.
I am not able to confirm the reasons why my
HR Manager would refuse to provide me with the letter other than that he stated it was because I wasn't in a managerial position and had never been. If I were to conjecture I would say that because he had told me that it was based off the same grading as salary he may feel that if he were to provide a letter it may leave him open to my requesting a salary review based on my 'new' grading. That said, I made it quite clear I wasn't looking for any salary adjustment.
I also understand fully your feelings on the remark he made. Unfortunately however I am not in a position where I could hope to find a similar position or salary in any short period of time without uprooting my family and moving city.
I am hesitant to use my current letter as it does not cover the complete 5 year entry requirement and they would no doubt ask for the letter to be updated anyway - I would prefer to get this all squared away before contacting the university.
At this point, I believe my best course of action will be to speak with my direct manager - the company CFO - and see if he is able to do anything to assist. Having completed an MBA himself, a letter of recommendation from him may go a long way towards showing eligibility. Perhaps a letter from him, in conjunction with the previous letter from
HR would be all I need.
Anyway, thank you again for your reply.
