All passenger ferries will remain docked across Greece on Monday, May 1, as the Pan-Hellenic Seamen’s Federation (PNO) will go on a 24-hour strike to mark May Day.
Among claims, the Greek seamen are demanding that their labor and social security rights are restored to pre-memorandum levels and that collective labor agreements will be in effect for workers of all categories of ships for 2017. The ferry workers are also protesting against uninsured labor and increased unemployment in their sector.
The strike will run 00:01-24:00.
Skopelosnews advises everybody who wanted to travel on this day to contact the ticket office/travel agency they have purchased their ticket with to get the latest information. In some ports there might be a strike but a boat might be allowed to travel. It has happened in Volos port.
Passengers whose trip is cancelled due to the strike are entitled to a full refund of their ticket.
No other announcements have been made at the moment that involve other means of transport.
