South African workers have launched a sit-in over 'broken promises', demanding permanent jobs.

Trade unions and workers marched through Johannesburg on Wednesday to demand permanent jobs, the insourcing of outsourced workers, and the reinstatement of dismissed employees.

Members of the Former Refugees Repatriation Association of Namibia (FRRAN), currently camping at the Swapo Party Headquarters, say they will not budge until their demands are met.
