The disinvestment minister Arun Shourie kick-started the privatisation of government-owned companies by divesting 25% of the government stakes in car maker MarutiUdyog in June last year.
The company says it already has a union, the MarutiUdyog Kamamgar Union (MUKU), at its Gurgaon plant and if workers at Manesar want a union, they should come under the MUKU umbrella.
