FBU general secretary Andy Gilchrist said: 'This is yet another attempt by diehard councillors to derail a deal. We reached agreement and they have come back demanding another late change over public holiday working.
'These are cheap, unworthy comments you would expect from councillors who clearly have no idea how the fire service operates. The public will be disgusted by these claims which are meant to insult and antagonise those who work in a highly regarded public service.
'Voters can give their verdict on Thursday on the actions and comments of these councillors when they will be held to account. The union will consider its next moves at its executive council meeting on Tuesday.'
