Security workers at London Heathrow Airport are to go on strike again in May for eight days.
The 1,400 workers, who went on strike around Easter, want a pay increase and called on the airport's management to "return to the negotiating table".
“Our members have been crystal clear they are seeking a substantial permanent increase in pay. A small one off lump sum payment will not alleviate the financial pressures our members are facing on a daily basis," said Wayne King, regional co-ordinator with Unite, the workers' trade union, which criticised the airport over the awarding of a 88% pay rise to outgoing chief executive John Holland-Kaye.
The strike, should it proceed, could cause disruption to travel from the airport, with aviation analytics provider Cirium saying 5,148 flights, equating to over 1.1 million seats, are scheduled to depart over the days proposed, with around half to be operated by British Airways.
