New Delhi/Chandigarh: The country's largest car maker Maruti Suzuki India on Wednesday hardened its stand against striking workers at its Manesar plant, saying it will not accept their demands despite production loss mounting to an estimated Rs 210 crore on the fifth day of the stir.

Worried over the impact of the strike to the state's industrial sector, Haryana government threw its weight behind the company terming the strike as "unwarranted", even as the agitators offered to work overtime, including Sundays, to make up for the loss if all their demands are accepted.

"When a union is not even registered, in today's condition how can we even think of accepting their demands? There is no demand of the workers which we can accept," Maruti Suzuki India (MSI) Chairman R C Bhargava said.

The striking workers are demanding the recognition of a new union -- Maruti Suzuki Employees Union (MSEU) -- formed by those working at the Manesar plant, besides retaining contract labourers for the two upcoming new units inside the complex.

They have also been demanding that no disciplinary action be taken against the 11 office bearers of the new union. The company has, however, sacked 11 workers, including eight office bearers of MSEU and three other employees, for allegedly inciting others to strike work.

Commenting on the ongoing strike, Haryana Industries Minister Randeep Singh Surjewala said: "Maruti is the backbone of our industry. The strike is unwarranted, even though the law gives the workers every right to form one more union".

Surjewala said the state government is closely monitoring the situation and will ensure that it does not take the shape of an "industrial dispute".

Meanwhile, component suppliers hit by the strike sought intervention of the government stating they have been forced to shut their factories due to inventory pile up.

According to industry representatives, about 250 units which are supplying auto components to Maruti's plant at Manesa have been affected by the strike.

On the fifth day, industry estimates put the value of production loss so far by MSI to around Rs 210 crore.

"Strike is continuing...production is fully stopped. So far we have lost production of about 4,200 units since Saturday," a company spokesperson said.

Taking note of the loss, the striking workers said they are willing to help the firm recover the output deficit.

"If our all demands are accepted, we will make up the loss by working overtime and on Sundays," MSEU President Sonu Gujjar said.

As the strike continued, the company's scrips closed the day at Rs 1,226.05 per share, 1.18 per cent down on the Bombay Stock Exchange.
