Over 1,000 secondary grade teachers in Chennai were detained for protesting for the fourth consecutive day, demanding equal pay for equal work. The teachers, who have been petitioning for 16 years, highlight a pay disparity where those appointed before June 1, 2009, receive a higher basic pay and overall salary than those appointed after that date. Two teachers sustained injuries during the protest when police forcibly removed them. The government has not yet responded to the demands.
