It’s not just natural disasters that can halt production – over in Indonesia, Honda was one of the many Japanese companies forced to stop output last Friday when more than 10,000 workers demanding better wages blocked a major highway, the Nikkei reports.

Police say the workers took to the streets around industrial areas in Bekasi, some 30 km east of Jakarta, effectively closing a highway connecting Bekasi to the heart of the capital and Jakarta’s main port and international airport.

Virtually all companies located at Sumitomo Corporation’s East Jakarta Industrial Park were forced to idle plants when the strike hit. “Operations at 4,000 to 5,000 companies may have been affected,” a government spokesperson was quoted as saying.

Every year, local administrators in the country set minimum wages for each district and sector, and the West Java government decided this year on a 20-30% wage hike in Bekasi. The Indonesian employers association filed a complaint with an arbitration body, which on Thursday ruled for a review of the raise, sparking the massive protest, the report added.

Although management and labour are expected to keep negotiating, West Java is preparing to appeal to a higher body to revoke the ruling. A protracted dispute will have an impact on the supply chains of Japanese and other Asian manufacturers, many of which use Indonesia as an export hub. For example, the world’s number one manufacturer of optical pickups, Sanyo Electric, has its main factory for the key component, which is used in DVD players and the like, in Indonesia.
