The union representing cabin crew in Belgium said it had turned down an offer by Ryanair ahead of a planned strike on September 28.
Ryanair had offered to follow Belgian employment law from March 2020 for Ryanair contracted employees, addressing one of the major complaints over the company's policy to staff under Irish contract.
The Belgian union, CNE, said that would only help about half of workers, as Ryanair has also been hiring under Crewlink contracts, the statement said.
The union said the offer was an "unacceptable" attempt to divide workers in order to buy time ahead of the planned strike.
The threatened strike by cabin crews in Belgium, Italy, the Netherlands, Portugal and Spain is aimed at pressuring shareholders set to meet tomorrow to address Ryanair's labour agreements, union officials announced last week.
The 24-hour strike is planned for September 28 and unions will strike once a month until demands are met.
The Belgian union met with Ryanair officials before announcing the strike and asked for an offer by yesterday. The offer was made yesterday evening, the union said.
A Ryanair board member said this week that its CEO Michael O'Leary would continue at the company's top for at least five more years.
Meanwhile, Ryanair today welcomed a French Supreme Court ruling in a Marseille employment case.
It said the ruling confirmed its position that the E101 certificates issued by Ireland in respect of its pilots and cabin crew who were temporarily based in Marseille are binding on the French authorities and the French Courts as previously ruled by the European Court of Justice.
Ryanair said the ruling now obliges the French authorities to accept and respect the Irish E101 certificates, which were issued to Ryanair's pilots and cabin crew who were temporarily based in Marseille from 2006 to 2010.
Ryanair’s Chief People Officer Eddie Wilson said the ruling now paves the way for Ryanair to consider re-entering the French market.
"We are already in discussions with a number of French airports, and the French Ministry of Labour, which we hope will lead to Ryanair announcing some bases in France in the near future, but with pilots and cabin crew based in France, on local French contracts, and paying their social taxes in France rather than Ireland," Mr Wilson added.
