Police tightened security at Suzuki Motor Corp.’s two-wheeler plant in Manesar near Delhi on concerns of labour unrest following the suspension of some union representatives, said two persons familiar with the situation.

Haryana police have deployed around 250 personnel at and around the factory, said Anil Kumar, a member of the union. Deputy commissioner of police Rahul Sharma, who oversees the area, said some precautionary steps had been taken by the police.

“There is some issue between the management and the union. There is no specific threat, but we have taken some precautionary and pre-emptive measures as some workers might go on strike tomorrow (Wednesday)," Sharma said. Suzuki’s car unit Maruti Suzuki India Ltd has in recent years been affected by a series of strikes, one of which turned violent resulting in the death of a manager, at its plant in Manesar last year.

“Our general secretary, Avinesh Kumar, was suspended a month ago because of a tiff between a plant supervisor and workers. We have been demanding his reinstatement," said Kumar. “However, today, they have suspended me as well as two other union members after a meeting with Haryana labour department. While the company says they will take us back after 42 days, there is no word on Avinesh’s reinstatement. If they do not take him back, we will have to look at other measures that includes a tool-down strike."

Emails sent to the company spokesperson and Atul Gupta, vice-president (sales and marketing), Suzuki Motorcycle India Pvt. Ltd, did not elicit any response till press time. Gupta did not respond to phone calls.

Suzuki’s Manesar plant has the capacity to produce 540,000 units a year and it rolls out as many as 1,500 two-wheelers per day. The plant is situated next to Maruti Suzuki’s plant in Manesar. Workers of the Suzuki Motorcycle union, along with other Suzuki units such as Suzuki Powertrain India Pvt. Ltd, had backed the strike by Maruti Suzuki workers in 2011. Later, Suzuki Powertrain was merged into Maruti Suzuki.

Kumar of the Suzuki union said the management had threatened to dissolve the union, but added that production continued to be “normal" at the plant on Tuesday. “We do not want anything from the management," he said. “We just want them to reinstate the suspended members. But they do not want a healthy relationship with us and often threaten to dissolve the union itself."
