HUNDREDS of workers at Heathrow Airport are set to strike in a dispute over outsourcing of jobs.
Unite said around 800 of its members will launch a week of strikes from May 7-13.
The union said workers in passenger services, who assist travellers to catch connecting flights, trolley operations, and security guards will have their jobs outsourced by June.
Unite general secretary Sharon Graham said: “Heathrow Airport’s actions are deplorable.
“It is raking in massive profits for the bosses while trying to squeeze every last penny out of its workforce.
“Unite is fully focused on defending its members’ jobs, pay and conditions, and our members at Heathrow will receive the union’s unrelenting support during this dispute.”
A Heathrow spokesman said: “We are reorganising our operations to deliver better results for our customers.
“There are no job losses as a result of these changes, and we continue to discuss with Unite the implementation of these changes for the small number of colleagues impacted.
“Unite’s threats of potential industrial action are unnecessary, and customers can be reassured that we will keep the airport operating smoothly, just like we have in the past.”
It comes as Unite members at Aviation Fuel Services will also walk out from 5am on Saturday, May 4.
At least 37 airlines at Heathrow face cancelling flights.
The union says new staff have been offered reduced pension and sickness benefits.
The carriers under threat of disruption include Virgin Atlantic, Emirates, Qantas, Air France, KLM, Air Canada, American Airlines and United Airlines.
