Ground staff at Liverpool John Lennon Airport are to stage a series of two-hour strikes.
Workers in the GMB union who work at Servisair were set to strike on Wednesday and Friday of this week.
The strike is against plans for 47 compulsory redundancies at the firm, which provides ground support to a number of major airlines.
A single two-hour strike is also planned for Sunday, followed by two more strikes on 28 November.
The union said it planned
to repeat the pattern indefinitely and it also announced a continuous ban on overtime.
Affected airlines will include Ryanair, KLM, FlyBe and Hungarian airline WizzAir.
