Protests are underway Saturday in Athens, Thessaloniki, and other cities over the 2023 Tempe train disaster and broader labor issues as Prime Minister Kyriakos Mitsotakis attends the 89th Thessaloniki International Fair.

Demonstrators, including relatives of Tempe victims, unions, student groups and leftist organizations, are calling for accountability, higher wages, affordable housing, stronger labor protections and collective labor agreements.

In Athens, protesters gathered at Syntagma Square, where the metro station was closed from 4 p.m., while police monitored the rally.

Maria Karystianou, head of the Tempe victims’ association, called the closure of the official investigation “immoral and dishonorable.”

In Thessaloniki, families of Tempe victims rallied near the memorial site. Union groups staged marches across the city. Authorities deployed more than 3,000 police officers in Thessaloniki to secure the fair and manage protests, closing six metro stations and imposing traffic restrictions.

Union leaders criticized the government’s handling of wages, inflation, housing and workplace protections. Workers’ union President Christos Panagopoulos denounced a proposed labor law allowing 13-hour workdays, calling it an attack on workers’ rights.
