I'm a non-trad, been working for 6 years since finishing undergrad. Obviously, an employer letter should be in the mix to talk about how awesome I've been in the years since college.
Here's the rub, though: A former boss who can best speak to my abilities is not the greatest writer. He may even be a little dyslexic, I'm not sure. He's more than willing to write an LoR, and I'm sure it would be glowing. But would a badly written LoR reflect poorly on me? Logically, I hope it wouldn't... But what would an adcomm think? I wish there was a way to get my boss to make sure he has somebody proof this letter for him. I'd like to think he will, but I can't exactly ask him to mix in a proofreader
