The Central Jakarta Manpower, Transmigration and Energy Sub-agency had sent written warning to 15 companies during inspections against 37 workplaces on Friday (1/15).

Supervision Division Head Kartika Lubis disclosed those companies had failed to implement health protocols.

His party would impose stricter sanctions in the form of temporary closure to companies that had been given written warnings if they still did the same case.

"Hopefully all companies implement the applicable rules made by the government, moreover the coronavirus case is still high," he asserted.
