When an EM gives you the word that I'm willing to match the offer and the role. What should you ask the EM to make it official?
A revised offer letter or an appraisal letter, or something else?
The more stuff you have in writing, the better. A revised offer letter seems good to me. I guess it would be a little different than an offer letter though, as it seems like you are negotiating with the EM at your current job to counter an outside offer.
Regardless, just get something in writing that looks official. 😃
