The Communication Workers Union says the SABC is on the brink of collapse.
This comes as the broadcaster saw disruptions on some of its platforms on Thursday.
The SABC claims the interruption was caused by power cuts.
But, the union says it’s clear the public broadcaster has no contingency plans to sort out the transition challenges.
The interruption comes after more than 600 employees were retrenched at the public broadcaster.
The union claims management targeted employees at the forefront of the strike.
