Leaders of the Banking Insurance and Finance Union will decide over the next few days whether to sanction a stoppage by its 7,000 members at the bank after a 53 per cent vote in favour of a walkout.
Leaders of UNiFI, the majority union at Barclays are to seek further negotiations with management after its 30,000 members voted by two to one for action short of a strike. UNiFI members voted by 53 per cent to 47 per cent against a stoppage.
Jim Lowe, assistant secretary at BIFU, said the union wanted a "short, sharp" campaign that caused the least disruption to customers, but got the message over to management.
Barclays calculated that a majority of its workforce had not voted for a strike. A management spokesman said the bank was confident that any action would have a minimal impact on customers. "Should any industrial action take place we will do everything to minimise its impact on services," the spokesman said.
