Calcutta, March 7 :    Calcutta, March 7:  Chief minister Buddhadev Bhattacharjee today asked central trade union leaders to shun militancy and settle labour disputes through peaceful negotiations with the management. Bhattacharjee was addressing representatives of 13 central trade unions at a meeting in Writers' Buildings. The meeting was convened to discuss industrial relationship with various trade unions in the state. He said: 'We are trying to improve the industrial climate in the state. I have met captains of various industrial sector to know their problems. Their main complaint is against labour unrest fomented by trade unions.'' 'Recent killings in a jute mill in Baranagar following labour disputes gave a wrong signal to industrial management and brought disrepute to the state. The government would never allow such militancy in the name of trade unionism. It is the responsibility of the government, management and trade unions to create congenial climate for investments,' he added. The meeting was attended by labour minister Santi Ghatak, commerce and industry minister Bangsagopal Chowdhury and power and industrial reconstruction minister Mrinal Banerjee. Among central trade unions representatives, were Citu's Chittabrata Majumder, Intuc's Lal Bahadur Singh and Aituc's Gurudas Dasgupta. Sharp exchanges witnessed between Ghatak and Dasgupta over the lackadaisical attitude of the state's labour department on genuine grievances of workers. Dasgupta alleged that thousands of cases on labour disputes were pending in tribunals for over a decade, thereby denying justice to workers. It is difficult for trade unions to find any assistance from the labour department or directorate now. 'Several posts of tribunal judges are vacant for many years. At least 32 vacant posts of assistant labour commissioners are yet to be filled up. The departmental minister cannot perform his duty properly due to his old age and chronic sickness,' he told the chief minister. Ghatak said that Dasgupta's department was insensitive to workers' plight. However, he admitted that he was sick and could not give more time to his work.
