Some unions representing employees on Athens buses and trolley buses decided to suspend their strike on Monday after a prosecutor launched an investigation into their failure to comply with a court ruling, which deemed their action illegal.

Employees on Athens buses, trolley buses, the Proastiakos suburban railway and Hellenic Railways Organization trains called rolling strikes until Tuesday in support of metro workers, who were forced back to work on Friday after nine days of action.

However, a first instance court in Athens decided over the weekend that the new strikes were illegal.

The first instance prosecutors’ office launched a preliminary investigation on Monday after the workers failed to appear for their morning shifts

Transit unions met on Monday to decide what action to take and voted to return to work.

"Management has called us for talks and we always said we would call of the strike if there was a willingness to hold discussions," Apostolos Raftopoulos, the head of the bus engineers' union, told Skai TV.

Unions representing bus drivers had not made a decision regarding the strike by Monday lunchtime.

Development Ministry sources hinted that the government would be prepared to issue civil mobilization orders, as it did with the metro, tram and electric railway workers, if other public transport employees do not return to work.

The Council of State over the weekend rejected an appeal by metro workers against the government’s decision to order them back to work.

Metro trains to Athens International Airport were stopping at Doukissis Plakentias station as a result of Monday’s strike as the remainder of the line is operated by OSE.

Public Power Corporation workers have called a 24-hour strike for Thursday in support of the metro workers and to protest the government’s use of civil mobilization to end their strike.
