I did a study once on the cost of attrition for my company (I did it to justify the cost of some employee investments I wanted to do that I thought would reduce attrition). It cost us the equivalent of a couple of hundred K, including opportunity cost, business disruption, and the cost of training your replacement. So no - it would be very hard for me to hire someone that I knew for sure was only going to stay a year.
Acknowledging of course that GF said he was looking to transfer within a year, not quit. This is more of an academic discussion now anyway
