Banking operations will be hit for the second time this month on May 21 with employees owing allegiance to various unions going on strike to protest Centre's "anti-labour" policies.

In a statement in New Delhi, All India Bank Employees Association demanded that the government give up the moves to privatise the banks, saying, "It is fraught with danger as the corporate sector, keen to takeover, will not repay huge chunks of money they owe to the nationalised banks."

The strike will be in protest against amendments in labour laws, Bank Nationalisation Act and Banking Regulation Act, an official of All India Bank Officers' Confederation said.

Apart from the bank unions, the central trade unions and PSU employees' unions are expected to take part in the strike.

However, BMS-led National Organisation of Bank Workers and National Organisation of Bank Officers have refrained from joining the strike, saying it was politically motivated and was in no way related to the demands of bank employees' wage revision.
