Hundreds of women brick-kiln workers from Punjab have come together in a rare gathering to demand equal pay and better accommodation, as the country's often invisible women labourers become increasingly vocal in their fight for rights...More than a thousand workers, most belonging to India's so-called lower castes and tribes, met in the city of Bathinda last week in perhaps the first such gathering in the country...The women workers in brick kilns are invisible - they are not recognised as workers, they don't get paid for their work, and they have no rights or benefits," said Gangambika Sekhar, an advocate with Volunteers for Social Justice, that organised the event.
