IndustriALL Global Union affiliates in Pakistan say workers warned management about cracks in a four-storey polythene factory before it collapsed on 4 November. The tragedy has so far claimed the lives of 23 workers, with up to 150 people still trapped in the wreckage of the factory building in Lahore...According to IndustriALL sources, workers saw cracks in the building a few days before the collapse and informed management but nothing was done in time. The factory, belonging to polythene bag manufacturer Rajput Polymer, had reportedly suffered damage during an earthquake more than a week ago and was undergoing building work to have additional fourth storey, allegedly without planning permission...Workers say they were being paid less than the minimum wage of 13,000 rupees per month (US$122) and were working 12-hour shifts.
