Baggage handlers at Liverpool John Lennon Airport held regular walkouts over Christmas and the New Year.
The GMB union members struck for two hours each morning and afternoon from 23 to 26 December, and again from 30 December to 2 January.
Employers Servisair are pushing through up to 35 forced job losses.
GMB regional organiser Eddie Parker said, “Servisair wish to make Liverpool Airport a hub for low-cost employees.
“While my members look to protect jobs at a cost to their own incomes, Servisair looks to reward shareholders by increasing profits.”
