Union officials have said it is determined to stop forced redundancies as it’s revealed Thomson Airways is looking to cut more than 600 jobs.
The company, which has entered a period of consultation with cabin crew, claims the job cuts are due to changes in their aircraft fleet and subsequent staffing needs.
But employees believe the numbers outweigh this.
Cabin crew union Unite said it wanted assurances that there would be no forced redundancies.
Unite regional officer, Kevin Hall said: "These cuts are a blow to the workforce and the airline.
"Unite is adamant that compulsory redundancies are out of the question and we expect firm assurances from Thomson Airways that they will not go down this route."
Thomson would not confirm the number of people affected by the cuts and said it was considering a number of options.
A statement by Thomson Airways said: "Thomson Airways will be entering a 90 day consultation period with members of the cabin crew this month.
"This is as a result of our continuing drive to become more efficient which includes changes to the aircraft fleet. Boeing 737-800 aircraft requiring fewer cabin crew are replacing Boeing 757s when they come up for renewal.
"Thomson Airways is committed to mitigating the impact of these changes on cabin crew and is working in partnership with the relevant trade union to achieve this result."
