Power utility Eskom, its contractors and organised labour were working to find a way forward to get all employees back to work at the Medupi construction site within the next two week.
The utility said on Wednesday that most employees had defied and ignored the court interdict, and final ultimatums, to return to work.
The unprotected strike began on March 25.
Eskom stated that some employees had been prevented from returning to work at the construction site, owing to violence and intimidation in the accommodation areas, as well as en route to the project site.
“The interventions by the project and contractor security teams, the South African Police Service included, have managed to contain the situation, but it remains tense.
“Over the past long weekend, the contractors released their employees to go home. These employees vacated the Eskom accommodation and have to await further instructions from their employer on when to return to work. The aim of this is to facilitate the execution of the contractors’ remobilisation plans,” the utility explained.
