Authorities in Indonesia´s capital on Saturday were cleaning up burned-out cars, government offices and bus shelters that were set ablaze by protesters enraged over a new law they say will cripple labor rights and harm the environment. Protests in many Indonesian cities turned violent Thursday. At least 20 bus stops and other transit facilities were destroyed in Jakarta, causing 55 billion rupiah ($3.7 million) in damage, said Jakarta Gov. Anies Baswedan. Calm has largely returned after the government warned protesters it won’t tolerate any further destruction and attacks on police and communities. Labor organizers staged a three-day national strike Tuesday to demand the government revoke the legislation. The Job Creation Law approved by Parliament on Monday is expected to substantially change Indonesia´s labor system and natural resources management. It amended 79 previous laws and was intended to improve bureaucratic efficiency as part of efforts by President Joko Widodo´s administration to attract more investment. The demonstrators say the law will hurt workers by reducing severance pay, removing restrictions on manual labor by foreign workers, increasing the use of outsourcing, and converting monthly salaries to hourly wages. Widodo told a televised news conference late Friday that the new law was meant to improve workers´ welfare.
