A union representing Athens electric rail (ISAP) employees will participate with early shift work stoppages during a nationwide 24-hour strike called for Thursday by the country's two largest trade union umbrella groups, GSEE, which represents the private sector but also a handful of state-run utilities, and the civil servants’ ADEDY.

ISAP trains will run as scheduled between 8 a.m. and 9 p.m.

Unions at TrainOSE, the rail operator, and the suburban rail, Proastiakos, will also participate in the 24-hour strike action. Service will be disrupted in at least 20 scheduled destinations on Wednesday and Friday, the days before and after the industrial action.
