Ministry of Justice National Offender Management Service
NOMS is committed to fairness for all. We insist on respectful and decent behaviour from staff, offenders and others with whom we work. We recognise that discrimination, harassment and bullying can nevertheless occur and we take prompt and appropriate action whenever we discover them.
A good aspiration. We hope that with increasing use of restorative practices, such behaviour will occur less often and be dealt with more effectively.
