bdnews24.com : Workers of Barpukuria Coal Mining Company Limited in Dinajpur have confined about 50 officials to the administrative building to press for retention of existing manpower. The workers encircled the administrative building on Wednesday morning to prevent the officials from coming out. Coal Mine Workers-Employees Union President Wazed Ali said the authorities had recently finalised a new manpower structure that would employ only 738 people instead of the previous roster strength of 2,674. On Apr 20, the workers had given the managing director (MD) an ultimatum to go back to the previous strength. Ali said they were compelled to protest due to the inaction of the management. A large number of police, Border Guard Bangladesh and RAB personnel have been deployed at the company premises to avert any trouble. The workers have been protesting against the new manpower structure since Tuesday.
