Description : Masons construct a concrete roof without safety equipment, using a motorized concrete mixer and ladders to hoist wet concrete in Tehatta. They create supports with wooden and bamboo poles, lay rebar mesh, and mix sand and aggregates while working near electric wires. Mason workers, known as ''karigars'' and ''mistris,'' perform tasks such as building walls, mixing mortar, and plastering in India's construction sector. Their work is physically demanding and subject to daily wage uncertainties and seasonal migration, with heat waves affecting their health and productivity. West Bengal, India.
