Johannesburg - Employees of Johannesburg City Power went on a strike on Wednesday afternoon, said officials.
A couple of hundred workers downed tools late in the afternoon, said spokesman Louis Pieterse.
“They worked during the day and downed tools at 4pm, saying they won't work after hours,” he said.
Pieterse said City Power was in the process of introducing shifts to its work rosters to improve service delivery.
He said this was because workers were sometimes needed to attend to outages after normal working hours.
“Unfortunately, there is a certain level of resistance by some employees which has resulted in unlawful work stoppages,” he said.
The workers were striking in their own capacities, and not under the auspices of a union.
Meanwhile, several areas in Johannesburg were without power.
Pieterse said the outages were widespread, but there was nothing serious to blame.
“We are experiencing some delays in response times and restoration times.... Contractors have been appointed to restore the power,” he said. - Sapa
