The South African Police Service (SAPS) employs approximately 163,000 employees. Of these, about 129,000 are functional police officers (members) employed under the South African Police Service Act 68 of 1995 (SAPS Act) who perform crime prevention and combat duties, while about 33,000 perform support functions and are employed under the Public Service Act 103 of 1994 (PSA). These support personnel include employees in call centres, community service centres, administration, supply chain management, finance, and human resources. In June 2007, during a national general public service strike involving several trade unions over wage disputes, the Police and Prisons Civil Rights Union (POPCRU), a registered trade union with approximately 109,500 members within SAPS, expressed an intention to call its members to strike. SAPS sought an urgent interdict in the Labour Court to prevent all its employees (both members under the SAPS Act and non-member personnel under the PSA) from striking, arguing that SAPS is an essential service and all its employees are prohibited from striking.
