Teachers in the Indian state of Tamil Nadu are demanding regular contracts and parity of pay with colleagues already employed permanently. They are also demanding that Tamil medium education be available from primary to high school.

Thousands of teachers blocked roads in Chennai and Trichy, resulting in hundreds of arrests. One report states that 30,000 were arrested across the state.

The school authorities in the towns are attempting to break the strike by roping in other staff, but with 100,000 contract teachers across the state on their third day of strike action that is proving difficult, with 92% in one area unable to function properly.

This is just the latest protest by contract teachers in India. It is an ongoing struggle across the country as it continues to rely on poorly paid 'temporary' staff - many of whom have given years of service. As in this case such struggles are often met with heavy handed policing.
