So I am the AM manager of a small, but extremely busy restaurant in LA, with a handful of cooks who work under me and the PM manager who is basically the head chef for all of us. One of the guys we hired a year ago wanted to take on more responsibility and learn some of managerial steps so we spent several months training him, eventually giving him a pay raise and a promotion of sorts. This has been going nice and smooth until he got a job offer from a place he applied with 4 years ago (not another restaurant). After receiving this news, he gave his ONE WEEK notice and that's that. I can't blame him for wanting to take a well-paying job, isn't that what we all want? And he has worked in this field in the past so it's entirely relevant for him to back into it but after pouring countless hours of training into this guy and losing him in a week, I'm a bit miffed. I felt that considering his newly acquired position in the restaurant, more notice would've been ideal or at least some hints that he was considering looking elsewhere. So what I'm left asking myself is, do I give him a good referral? He worked very competently for the last year and was always a trooper in the most dire of situations but I run a small, tight crew and losing him will place a pretty substantial workload on the rest of his crew. Do I just tell prospective employers that he was great for the last year but he screwed me over right at the end? Trying to use my logic instead of the frustration this situation is causing me. Insight is greatly appreciated.
