A Greek court has ruled illegal a four-hour work stoppage announced by the country’s air traffic controllers for Thursday, ensuring that scheduled flights will proceed as planned.

The Hellenic Air Traffic Controllers’ Association had called on members to walk off the job from 9.30 a.m. to 1.30 p.m. in support of a 24-hour strike declared by Greece’s main public sector union, ADEDY.

ADEDY said the nationwide strike is intended to protest a government bill introducing changes to disciplinary law for civil servants, which is scheduled for a parliamentary vote this week.

The Athens Court of First Instance deemed the controllers’ action unlawful, preventing potential disruptions during the peak holiday season.
