Dozens of employees of Klub Golf Senayan in Central Jakarta demonstrate on Tuesday outside the management's office.

The gardeners, housekeepers, waitresses and security guards demanded a transportation and a meals allowance on top of their basic salary.

The workers' monthly pay, across the board, is Rp 820,000 (US$89), their spokesman, Agus Woro, said. The provincial minimum wage is Rp 812,000.

They were paid just Rp 720,000 before a letter was sent to the management last month, he said. "How can we support our families on that meager wage. It's just not enough," he said.

The workers threatened strike action. Four of them were invited into the office to discuss the problem. They reported that the company had asked for a month to consider the demand. Besides a wage increase, the protesters also want to be put on contracts.

None of the executives at the golf club, which is run by PT Sinar Kemala, were willing to speak to reporters.
