Purbalingga – Half of all workers in Purbalingga regency in Central Java are not registered with the state social security company, PT Jamsostek, an executive said Wednesday.

"The number of workers who aren't insured with Jamsostek has reached 15,000, or half of the total workers in the regency," Jamsostek Purwokerto branch head Mulyadi said during a meeting with company owners in Purbalingga.

He added most workers in the regency, about 30,000 people, were employed in foreign-owned companies producing artificial wigs and eyelashes, mostly for export.

"We appreciate the companies' contribution in reducing unemployment," Mulyadi said. "But we regret the fact that they have neglected their workers' rights by not registering them with Jamsostek."
