The walkouts will be held throughout March and April in the lead-up to Easter (12 April) and could, says Unite, affect passenger air travel and freight services.
Unite represents around 80 Vanderlande employees at Heathrow. The firm operates luggage belts at Terminal 3 and passenger baggage transfers from One World Alliance, Virgin Atlantic and Emirates aircraft.
Staff of the Dutch ground handling firm are also responsible for loading and unloading freight from IAG aircraft, including British Airways, Aer Lingus and Iberia.
Vanderlande’s Unite members at Heathrow voted 88.6% in favour of strike action on a 90.9% turnout following what Unite described as a “breakdown in industrial relations” with the company.
It comes after staff last year rejected a 2.5% pay offer, and a subsequent 3.2% pay offer owing – said Unite – to Vanderlande refusing to accept its recognition agreement with the union applied to new employees, who would therefore not receive the pay increase.
Vanderlande staff at Heathrow will walk out between 3am and 11am on 14 March; from 12.01am on 27 March to 11.59pm on 28 March; from 12.01am on 3 April to 11.59pm on 4 April; and from 12.01am to 11.59pm on 9 April.
Unite regional coordinating officer Wayne King said: “Vanderlande’s transparent attempts at union-busting have bolstered our member’s determination to achieve a fair pay deal for all staff.
“Vanderlande’s strong arm tactics mean the airport now faces Easter holiday chaos and delays across March and April that will impact air travel and the movement of cargo to and from Heathrow.
“Unite urges Vanderlande to rethink its position and approach to staff and engage with the union before the strikes commence. It is possible to avoid a shutdown if the firm stops trying to split the workforce and tables a sensible pay offer for all our hardworking members.”
TTG has approached Vanderlande for comment.
A spokesperson from Heathrow said: "A small number of Vanderlande colleagues who provide baggage services at the airport have voted to take industrial action.
"Vanderlande have put into place robust contingency plans and we are working with our partner to ensure this does not affect services at Heathrow."
