The government officials, however, said the proposed moves are aimed at improving ease of doing business and are not necessarily 'anti-workers'.
According to one of the proposals, registering a trade union will require at least 10 per cent of the employees or 100 workers, in contrast to the current requirement of seven members, regardless of the size of the establishment.
These are part of the draft Labour Code on Industrial Relations Bill, 2015, prepared by the Labour Ministry, while proposing to combine Industrial Disputes Act, 1947, the Trade Unions Act, 1926, and the Industrial Employment (Standing Orders) Act, 1946.
The government will meet union and industry representatives on May 6 to discuss proposals of the draft of the Labour Code, a senior Labour Ministry official said.
Reacting to media reports that it is "anti-workers", the official said: "It's a misconception that this Bill is anti-workers as we have proposed to increase compensation for workers in certain cases of a job loss to 45 days' pay, from the existing provision of 15 days."
He added, "The existing law has undoubtedly encouraged registration of trade unions. But there are cases where there are more than one trade union in one industrial unit, employing not even 50 workers. Thus, this large number of unions is serving no purpose there.
