Hello, “Full name”,
I got your request for a letter of recommendation yesterday and the expectation you will comprehend in the event that I decline. Letters of recommendation convey the most weight when they are from individuals, for example, associates and administrators who know your activity aptitudes and work propensities. We work in totally various divisions of the organization, and I have known you for such a brief timeframe, that I can barely talk with power about your expert capacities.
The reason for not issuing a recommendation letter is not personal but it’s just that I am not well acquainted with your recent achievements in the field which might help you in your future jobs and hence wouldnt be doing justice to your skills and talents. I am complimented that you would request a recommendation from me, yet as an issue of technique in your pursuit of employment, I think another person would be a superior decision. Do let me know if you want me to talk to some of your professors for this letter.
Good luck in your pursuit of employment!
