The Unite union has announced fresh industrial action involving security officers at Heathrow officer.
A total of 1,400 members of the union will walk out for eight days over the course of next month, with strike dates set for May 4, 5, 6, 9, 10, 25, 26 and 27.
Workers involved in the industrial action include staff at British Airways’s Terminal 5 hub, as well as security guards responsible for checking cargo entering the airport.
The first round of strikes will coincide with the coronation of King Charles III, which takes place on Saturday May 6.
Aviation analytics firm Cirium has published data showing that a total of 5,148 flights are scheduled to depart Heathrow over the eight days of strikes – of which 2,621 are scheduled to be operated by British Airways.
The latest round of industrial action follows a similar ten-day strike period involving Heathrow security staff over the Easter holidays.
Commenting on the news Unite regional co-ordinating officer Wayne King, said:
“Strikes next month will cause further disruption to airport passengers but this dispute is a direct result of Heathrow’s stubborn refusal to make an offer that meets our members’ expectations.
“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.
“While the CEO can enjoy a lavish millionaire’s lifestyle, our members struggle to pay the bills and put food on the table. This is about need not greed.”
