Thousands of Indonesians took to the streets of several cities Tuesday to protest the passage a day earlier of a jobs law they say is too pro-business, but which the government has promoted as vital to attract investment.

President Joko Widodo's "omnibus" job creation bill was passed three days ahead of schedule, revising over 70 existing laws to accelerate reform of Southeast Asia's largest economy.

The passage also came a day before the start of a three-day national strike, which unions expected to involve two million workers in protest against the bill.
