Low-cost airline Ryanair's Spanish cabin staff will go on strike for six days in late June and early July, its main unions said on Monday.
The staff will walk out on June 24th, 25th, 26th and 30th, and on July 1st and 2nd, as they are unhappy with working conditions and pay, USO union said.
"We have to resume mobilisation so that the reality of our situation is known and Ryanair is forced to abide by basic labour laws," the general secretary of USO's Ryanair section, Lidia Arasanz said in a statement.
Staff of the Dublin-based airline, the largest in Europe in terms of passenger numbers, have walked out in other European countries such as Belgium and Italy.
With most Covid-related travel restrictions lifted in many countries in recent months, demand for summer travel has bounced back, leaving airlines and airport operators struggling to hire staff fast enough to handle the flow of passengers and offer them attractive working conditions.
