Historically people did not come back to J2 from TUI but those days have ended. Several returns from TUI are in the system for this training season, and I personally know two recent rejoiners: one from BA and one from Virgin, both citing lifestyle, the former felt like just a number at BA, the latter wanted to be home to see his kids grow up. I was pleasently surprised to see a grown up response to their returns from the company, no interview was required just a quick sim check to keep HR happy and within, 6 months they both were on command courses.
