KARACHI: Chairman Pakistan Peoples Party Bilawal Bhutto Zardari has felicitated the Peoples Labour Union over its victory in the referendum for Port Qasim Authority (PQA) as Collective Bargaining Agent (CBA) that was held a day earlier. Peoples Labour Union obtained 669 votes defeating its rival, which was supported by many political parties, by a margin of 125 votes in the referendum. PPP is the only political party in Pakistan, which implemented labour policies and struggled for the rights of workers, introduced trade union rights in the country and made them partners in the national industrial and commercial units through Benazir Employees Stock Option Scheme, Bilawal added. He assured the labour class that its interests would always be kept on high priority and no one would be allowed to crush their aspirations. Bilawal congratulated the new office-bearers of PQA-CBA and exhorted them to contribute their efforts for strengthening the party in continuing its struggle for all the downtrodden masses of the country.
