The unrest at Maruti Suzuki

Workers beat up management and set the Maruti factory to fire. This is a Japanese collaboration that sells the majority of cars in India.  It is time to look at the worth ethics of this seemingly clean company. People who work there at all levels have been unhappy for some time. Physical violence of this scale is unheard of at other work places in India. I wonder what the Japanese management did to disturb Indian workers so.
