Workers and labour class had played a key role in statehood movement and stood by Telangana protagonists, MP Kavitha has said. Participating as chief guest in May Day celebrations at Telangana Bhavan, the headquarters of the TRS here on Sunday, Kavitha asserted that nation will witness growth and development when working class is a happy lot. International labour Day is noted for the labour class getting united to fight against the tyranny of industrialists and big businessmen who used to harass them. And now that situation has changed to much extent though the working class is facing problems, she said. (Photo: Zabi)
