A one-day strike called by state banks on Tuesday will have minimal impact on banking services. However, cheque clearances will mostly likely be hit. The Unions under the aegis of United Forum of Bank Unions have threatened to go on an agitation today. At the heart of their joint stir is a demand that loan defaulters be brought to book, bank officials be paid compensation for the extra work they took on during demonetisation and easing of pain resulting from privatisation of government banks.
