additionally, I have just thought of this, if management didn’t support the banding appeal, it was unusual, at least in my service, for it to get to appeal stage because the manager had to be told and at that point if there had been accidental job drift away from the job description, it would be quickly stopped. In practice of course, the staff member had often discussed the issue with their line manager before doing anything formally and it would be a foolish manger who allowed a valid appeal, which they did not support, to go ahead. In certain circumstances also, its quite legit to allow (but not insist) someone who is at the top of their band, to take on certain tasks and responsibilities of the next band up as a development opportunity on the strict understanding that this is not a legitimate argument to put forward at banding review and that the arrangement is severely time limited.
