DUBLIN (Reuters) – British Ryanair pilots have expressed strong support for calling strikes to raise wages and improve working conditions in a survey carried out by the BALPA union, according to a report seen by Reuters.

The report, sent to union members on Monday, said that 90 percent of the pilots surveyed would support the strike call, although it did not indicate the number of pilots surveyed.

BALPA is scheduled to meet with Ryanair on Tuesday, according to the report. BALPA and Ryanair did not respond to the request for comments.

Ryanair faced tough strikes last year after the airline gave in to pressure at the end of 2017 and recognized the unions for the first time. This influenced obtaining the lowest annual benefit in four years, according to figures published last month.

The largest low cost airline in Europe has managed to calm tensions by reaching agreements on wages and benefits with many unions in Europe, but has yet to go beyond the recognition agreement signed with the British union BALPA almost 18 months ago .

The CEO of Ryanair, Michael O'Leary, said in May that he did not expect this summer to be interrupted by labor issues, but that it could not be ruled out completely.
