Zimbabwe's Public Service Association, representing state workers, said its members will go on strike unless they see results from ongoing pay negotiations with the government.
Negotiations opened last week but government representatives requested 14 business days to consult their principals.
The association wants entry level salaries of US$402 with another US$100 allowance for housing and transport. Civil servants now earn US$140 a month.
Association Executive Secretary Emmanuel Tichareva told reporter Jonga Kandemiiri that the group is looking forward to seeing the government's offer after Sept. 10.
