Aer Lingus customers can expect disruption to theairline's services from Wednesday, June 26.
To what degree is yet unclear.
The Irish Airline Pilots' Association (IALPA) has served notice to Aer Lingus of an indefinite work-to-rule from next Wednesday June, 26.
According to RTE, In a statement, IALPA said this will involve the pilots not working overtime or "any other out of hours duties requested by management."
It will also involve the pilots only working the published rosters and "not accepting or working any amendments to published rosters."
"This includes no Friday changes and no changes on or prior to the day of operation."
The pilots, according to the RTE report, will also not log into the Aer Lingus portal or 'e-crew' outside of work hours, nor will they answer phone calls outside of work hours.
Aer Lingus pilots, who are members of the Irish Airline Pilots' Association, voted overwhelmingly on Monday in favor of industrial action, up to and including strike action.
A Work to Rule action falls short of a full strike, but can still lead to significant service disruptions.
