A planned strike by workers is threatening to disrupt Easter holiday travel at Heathrow Airport next month.
Baggage maintenance engineers have voted to walk out between 8 and 10 April in a row over pay.
Employees of Vanderlande Industries manage the airport’s entire luggage handling system.
The strike would affect all airlines operating out of Heathrow, including British Airways, Air France and KLM, the Unite union has warned.
Unite says more than 160 workers voted in favour of striking after being told their pay would be frozen despite Vanderlande Industries reporting a growth in revenue for 2021.
Unite General Secretary Sharon Graham said: “Employers across the sector are on notice that our members are ready to fight back against the sustained and opportunistic attacks against jobs, pay and conditions that have blighted this industry for far too long.”
Unite Regional Officer Lindsey Olliver urged Vanderlande to ‘put an end to this dispute by tabling an offer our members can accept’.
A planned strike at Heathrow last month by HGV workers was called off after members accepted a renewed pay offer.
A spokesperson for Heathrow said: “We are aware of planned industrial action from Vanderlande Industries colleagues who operate at Heathrow.
“While we are not involved in the pay discussions, we will of course remain in close contact with Vanderlande Industries and other airport partners when it comes to our operations, including helping them to mitigate any passenger impact should the planned industrial action go ahead.”
