Cabin crew at Ryanair have voted to accept a 10% pay cut which will gradually be restored over a 4-year period.
The wage reductions were triggered by the effective shutdown of the aviation industry due to the Covid-19 virus.
According to the cabin crew union Forsa, the proposals were accepted by 62% of those who voted.
The turnout was 68%.
Forsa stressed that the agreement contains a review clause, along with a commitment from Ryanair to continue negotiations with the union on an overall collective labour agreement in issues including annual leave, base transfers and early transition for agency crew.
Fórsa official Ashley Connolly said the deal reflected the severity of the crisis faced by aviation generally, and was intended to protect as many jobs as possible in anticipation of an eventual recovery.
"Our cabin crew members understand the severity of this crisis. They've backed an agreement that protects their job and provides for a review of circumstances should they improve sooner than expected. Equally, it was important for us to have the restoration of pay built in to the agreement," Ms Connolly said.
She stressed that amid uncertainty about the future of the sector and the timeline for recovery, Forsa would remain focused on maximising protections for Ryanair workers.
Under the deal, a bonus of up to €1,800 a year for cabin crew which was due to expire in March 2021 will be replaced with a basic salary increase of €900 gross per year in July 2023, and €900 gross per year in July 2024.
"This is designed to provide more certainty of earnings for cabin crew, as well as increasing the proportion of fixed pay as pay is restored over the four year duration of the agreement," the union stated.
