DH has been acting up in a managerial role for 4 years but the post was never made substantive, in spite of his requests. He has now been told that his job is at redundancy risk, and faces being redeployed to another role, not matched to his current pay band, but one before current job. The effect would be a demotion and pay cut of £5k a year. He is public sector and Human Resources argue that they can do this, because technically he was never appointed to the role, in spite of succeeding at interview. I don't think this is fair given the fact that he has been in the role for 4 years; he is not a probationer, but well established in the job. Any legal beagles able to give us a view on whether we can challenge? Many thanks.
