There is no timeframe for the retraining. From what I have read, the transition takes place within a set period. It is not as if someone had to learn completely new skills that had nothing to do with his or her training. I do not think that people can just pick any skill set they want, regardless of the cost and time involved. We unfortunately have to take into account cost effectiveness, and the retraining needs to happen within a reasonable time. We have to look at the cost and the time involved.
