For many operators a current IR is an absolute must, especially when recruitment is in a boom cycle. Interview on the Friday, pack suitcase at the weekend, and away on TR on the Monday. They dont have time to sit and wait for people to go an revalidate ratings. Not current...no interview. Harsh but true im afraid. At the moment however, its not even worth doing an IR in the first place. Anyone doing an IR just now would be as well booking their renewal for next year.
