Millions of workers began a nationwide two-day strike across India on Monday to express their anger at the government’s economic policies and to back demands for improved rights for industrial workers, employees and farmers.

About a dozen of the country’s labor unions that have organized the strike want the government to provide universal social security cover for workers in the vast unorganized sector, hike the minimum wage under its flagship employment guarantee program and stop the privatization of the public sector banks.

The strikers are also demanding the government halt its plans to monetize state assets.

Indian Prime Minister Narendra Modi’s government says privatizing some state-owned banks would overhaul the banking industry and that the asset monetization model will help raise money to spur economic growth.

All Indian Trade Union Congress, one of the largest trade unions in the country, said it was expecting more than 200 million formal and informal workers to join the strike. Demonstrations were planned in New Delhi, Mumbai, Kolkata, and other major cities.

The Bharatiya Mazdoor Sangh, an important trade union affiliated with the ruling Bharatiya Janata Party, said it won’t be participating in the strike, calling it “politically motivated.”
