United argues the deal fails to recognise their hard work and the rising cost of living.
The union is meeting Menzies today to urge them to resolve the dispute.
Strike action by workers employed by Menzies Aviation is due to begin at 03:00 on July 20th, concluding at 13:59 on July 22nd.
According to the company’s latest annual report, Menzies Aviation increased its underlying profit by 72 per cent to £58.8 million and workers believe the company can do more to recognise the contribution they have made to the success of the company.
Unite regional officer, Jeff Hodge, said: “Menzies Aviation boosted its profits by a massive 72 per cent and workers at Luton Airport believe the company can do more to recognise their hard-work.
“Baggage handlers have also accused Menzies of failing to communicate, breaking agreements and reneging on promises including a commitment to improve working conditions.
“Unite is meeting with Menzies today and we urge them to recognise the workers’ grievances and resolve this dispute.”
