The Finance Minister Arun Jaitley has appealed to bank employee unions to call off their proposed four-day nationwide strike from February 25. Public sector banks (PSB) employees and their unions should not resort to agitation approach by participating in bank strike, Jaitley said in a statement here. Banks are already in negotiations with their unions and associations for wage settlement and that bipartite negotiations in a cordial manner is the only available tool for settlement, he said. Bank unions should not resort to disruptive means, and call off the call for strike, he appealed. PSB employees had given a call to go on a countrywide strike from February 25 to press for their wage related demands.
