RCN members overwhelmingly backed the deal, with 93 per cent voting to accept it, while 65 per cent of Unison members voted in favour.
However, 95 per cent of Unite members rejected the pay offer and will be balloted on industrial action. The Royal College of Midwives and the GMB have also rejected the deal.
Unite assistant general secretary Gail Cartmail said: 'Our members are angry and frustrated that they are being asked to accept this woefully inadequate three-year pay deal.'
She said it was effectively 'a substantial pay cut when you take into account the inflationary trends in the economy.'
Unite's health sector national officer Karen Reay said that the call for a ballot for strike action was 'unprecedented'.
