Workers at London Luton Airport could vote to take part in a series of strikes starting on Boxing Day in a ballot being held this week on proposed wage cuts.
The Transport and General Workers' Union (T&G), which represents 800 airport employees, is fighting plans by the airport to reduce pay for its members by between 30 and 50 per cent.
Employees are now being balloted on whether they want to accept an improved offer from the airport, which includes bigger compensation packages and increased long-service payments for those workers who decide to leave.
Russell McCallion, human resources director for London Luton Airport, said he thought the new deal on the table was generous.
"We believe that this is a very fair and reasonable offer," he added.
McCallion added that if strike action was taken, contingency plans were in place to keep the airport open.
A spokesman for the T&G said that the result of the ballot would be announced on Thursday (21 December).
If the improved offer is rejected, four-hour strikes will be held on 26, 27, 29, 30, 31 December and 1 January.
