Ryanair (LON: RYA) cabin crew from Spain, Italy, Portugal and Belgium are set to go on strike this month.

The airline’s employees will walkout on 25 and 26 July, in a move that is likely to disrupt flights to popular holiday destinations.

“The decision that Ryanair took in December to recognise unions was welcomed, but that came in among years and years of complaints across the workforce about conditions, pay, all of the issues listed in the charter,” said international Transport Workers’ Federation campaigns director, Liz Blackshaw.

“No progress has been made, despite Ryanair claiming to be in talks with unions across Europe. Ryanair needs to sit down with the unions they’ve been talking with and actually address the conditions of work being complained about and address the charter.”

The budget airline has described the strikes as pointless, maintaining cabin crew working for the airline have good conditions.

Pilots based in Ireland have planned to walk out on 12 July. Up to 117 pilots in the Irish Airline Pilots’ Association (Ialpa) union are expected to take part in the strike. According to Ryanair, this is less than a third of the pilots it employs in Ireland.

“Ryanair will deal with any such disruptions if or when they arise, and we apologise sincerely to customers for any upset or worry this threatened action by less than 28 percent of our Dublin pilots may cause them over the coming days,” said the airline.

Unions have called on the airline to end agency employment, give staff the right to sick pay and end strict sales targets for products sold onboard including scratchcards.
