Unions representing Athens public transport workers on Tuesday decided to suspend a 24-hour strike, with press reports pointing to a tougher stance adopted by the transport ministry, which notified company managements to file legal action against the industrial actions as "illegal and abusive".

A court ruling on the lawsuits filed by the metro, electric railway (ISAP) and tram managements is expected later in the afternoon on Tuesday.

ISAP electric rail workers decided to suspend a 24-hour strike announced for Wednesday and instead will hold a four-hour work stoppage between noon and 4 p.m.

Buses will also participate in the work stoppage, while trolley buses, the all-important Athens metro and the Proastiakos suburban railway will run as scheduled.
