 MetCC retains sufficient police officers to maintain the 999 answering and Dispatch service should civilian staff strike, in posts identified as requiring a police officer in legislation, and in senior and intermediate positions where command is exercised.Each of the three Metcall centres has two Duty Officers on duty at any given time (making a total of six on duty across the three centres).One of the Duty Officers is always a serving Inspector, whilst the other is always an experienced member of the civilian staff.
