Public-service unions will announce on Tuesday if a revised wage offer from the government has been accepted, an official said.
Public workers on Friday put off a threatened national strike, saying they would consult on a new wage offer from the government.
A smattering of striking public-service employees began to march from Schubart Park to the Union Buildings in Pretoria on Tuesday morning.
Unions have rejected the latest offer from government, increasing the possibility of a public service strike next week which could shut down schools.
The public service and administration department said on Monday it would be meeting unions again this week in a bid to avert a potential strike.
