The local motor manufacturing industry will be heavily affected as Cosatu stages a national stayaway. Seven on the country's manufacturers are expected to halt production at their plants.
The Congress of South African Trade Unions (Cosatu) is staging a stayaway in protest of high food and power prices.
While various measures have been taken to ensure minimal impact, SABC News reports that the local motor manufacturing industry has indicated that assembly plants will be closed for the day.
The industry employs more than 30 000 people and thousands are expected to support the Union action.
Two weeks ago, General Motors SA and Volkswagen SA shut down their plants when faced with worker absenteeism resulting from a Cosatu strike.
