Cabin crew at Ryanair are threatening co-ordinated strikes in four countries this summer.
The warning came as a list of 34 demands was published following a union-organised cabin crew summit in Dublin.
The so-called Ryanair cabin crew charter outlines changes the low-cost carrier must make to bring it in line with comparable employers, according to the International Transport Workers’ Federation (ITF).
But the airline has described the charter as “pointless”.
It contains demands on economic conditions, safety and rostering, a “fair and supportive” work culture, agency employment, the right to sick pay and sales targets.
A key demand is that employment contracts “explicitly recognise” national law and jurisdiction in the country a worker is based.
The summit was organised by the ITF and the European Transport Workers’ Federation, as part of the Cabin Crew United alliance of trade unions.
Staff representing around 80% of Ryanair’s cabin crew workforce and 100% of its ground crew workforce attended.
Ryanair finally announced that it would recognise unions in December following intense pressure from workers.
But unions claim little progress has been made over the last six months “and there have so far been no concrete improvements in pay or working conditions” at the airline.
A joint statement said: “If Ryanair fails to respond promptly and appropriately then it risks industrial action over the summer.
“The ITF and the ETF support all lawful industrial action undertaken by their national affiliates with the aim of winning a fair deal for workers.”
The treat of strike action came as Ryanair said 71 out of 441 flights this morning were delayed due to French and German air traffic control staff shortages.
