The ex-workers joined to form the 559-strong Ex-Mercury Employees Welfare Association and in 2006 filed a Public Interest Litigation (PIL) suit in the Madras High Court. The association wants an economic rehabilitation scheme, healthcare treatment and a monitoring programme at the company's expense for everyone who ever worked in the factory. It also wants the company prosecuted. Hindustan Unilever denies that any of the health problems of the workers or their families were the result of mercury exposure in the factory. In 2010 the workers were still fighting for compensation.
