The Union of Greek Air Traffic Controllers on Monday called on its members to take part in Thursday’s strike by ADEDY, the civil servants’ union.
ADEDY has called a 24-hour strike to protest the government’s pension reforms.
There will also be a rally in Klafthmonos Square, central Athens, at 11 a.m.
It is not clear if the call from union leaders will lead to a strike by air traffic controllers as these are often blocked by the courts.
Anyone traveling to or from Athens International Airport on Thursday should contact their airline for more information.
