Officials from the Amicus section of Unite, the union representing the 11,000 cabin crew, rejected British Airways' latest offer earlier this month.
Unite joint general secretary Tony Woodley said: "Regrettably, we have not found it possible to resolve the outstanding issues concerning cabin crew. BA's continued hounding of union members leaves us no other option but to conduct a new industrial action ballot."
- An immediate restoration of staff travel concessions, in full, to the crew from whom they were taken by BA
- Binding arbitration, through Acas, of all cabin crew disciplinary cases related to the dispute
- Restoration of the wages docked from crew who were genuinely off sick during strike dates
- Full and proper discussion of the trade union facilities agreement at the company with the immediate removal of all threats and sanctions made by BA in relation to this.
Unite said it expects to serve notice of an industrial action ballot to BA shortly, set be completed in early January.
BA said in a statement: "Unite has changed its position yet again, calling for fresh talks then announcing a strike ballot before such talks take place. Should any industrial action take place, we are confident that our well-established contingency plans will allow us to operate normal timetables at Gatwick and London City airports. At Heathrow, we will aim to run a substantial proportion of our short-haul programme and 100% of our long haul operation."
