For four hours yesterday operations in the Johannesburg high court came to a halt as officials picketed outside the building ahead of a strike.
Carrying placards bearing the words - Fraser Stop Insulting Us With 6,5% - the officials, mostly members of the National Education, Health and Allied Workers Union, sang and toyi-toyied at the entrance of the court.
Clement Marule, Nehawu's national organiser and negotiator, said his duty yesterday was to mobilise workers and "make them more angry".
He said that from Monday Nehawu members will embark on an indefinite strike.
This follows the government's refusal to grant the workers demand of a 12percent wage increase.
Marule said the union will provide skeleton staffs in courts and other essential public services.
He warned that the union would consider removing skeleton staffs if government failed to meet their demands.
Patricia Khumalo, 64, a cleaner, said "very little has changed" since she started working at the court 28 years ago.
