The strike by workers at Maruti Suzuki India's Manesar plant entered its seventh day on Thursday, with no sign of an end despite the Haryana government declaring it illegal.

"The workers are still on strike and there is no production at the plant," a company spokesperson said.

Simultaneous strikes by workers at Suzuki Powertrain India Ltd (SPIL) and Suzuki Motorcycle India Pvt Ltd (SMIPL)

in support of their colleagues at MSI are also on.

On Thursday, the Haryana Labour Department had declared the strike by MSI workers illegal and said it breached the settlement agreement signed on October 1 to end a 33-day-long standoff.

The department had also said it would initiate action to derecognise the unions of SPIL and SMIPL.

In the meantime, different trade unions have called for a protest rally in front of MSI's Manesar plant on Thursday afternoon.
