One of the best jobs I ever had is one I left on my own terms 3 years ago (had decided to go back to college and move halfway across the country) and while there, I got along well with several in upper mgt. We kept in touch for a bit, however it's been awhile now and I need to update my resume .. would like to keep them on my resume not just for employment history but references, but if they're not responding .. any advise on what I should do? If they don't respond do you think I can contact a co-worker (who had a lower position than me at the time) and see if he'd be ok with my listing him as a reference for that job?
I did friend request on FB one of the regional managers but he never accepted it. I do know the co-worker (who has since been promoted to my past rank) is on there however.
