The Office of Manpower Economics is an independent secretariat. It advises and supports 8 Pay Review Bodies. These make recommendations on the pay of 2.5 million workers in the public sector. This is 45% of all public sector staff with a paybill over £100 billion between them. The 8 pay review bodies are: • Armed Forces' Pay Review Body (AFPRB) • Review Body on Doctors' and Dentists' Remuneration (DDRB) • NHS Pay Review Body (NHSPRB)• Prison Service Pay Review Body (PSPRB) • School Teachers' Review Body (STRB) • Senior Salaries Review Body (SSRB) • National Crime Agency Remuneration Review Body (NCARRB) • Police Remuneration Review Body (PRRB) The Review Bodies are independent of government and their recommendations are evidence-based. They advise the government on levels of pay for their remit groups.
