In two meetings — one at Triplicane beach and the second at the beach opposite Madras High Court — the Comrade, known for being one of the leaders of Self Respect movement in the Madras Presidency and for his fight for the rights of backward classes, passed a resolution stating the government should allow everybody a national holiday on Labour Day.
