Durgapur, Nov. 10: The Citu leadership in Bankura today said it was planning a good-manners class for supporters, four days after some of them beat up two senior officials of a factory in Barjora.

Kinkar Prasad, the district secretary of the CPM's labour arm, said: 'We are planning to organise a workshop and train them in the dos and don'ts at factories. We feel embarrassed that our supporters have again come to the fore for violent trade unionism.'

Insiders said the assault on the general manager and deputy general manager of Rishabh Sponge Iron Pvt Ltd on Sunday has put the district Citu leadership under the scanner. Chief minister Buddhadeb Bhattacharjee has over the years repeatedly asked the state Citu brass to give up the militant path.

Prasad admitted that his supporters often turned violent. 'We have made it clear that they will have to change their ways,' he said. 'The factory is their bread and butter. Without industries where will they go'

Bankura has seven sponge iron factories and an equal number are in the pipeline with an investment prospect of around Rs 200 crore.
