Specifically, Lines 1 (ISAP), 2 and 3 of the Metro, as well as the Tram network, will not operate from the start until the end of the daily schedule.

In their announcement, STASY workers’ unions stated:
“We honour Labour Day and announce our participation in the 24-hour nationwide strike (from the start of service on Friday morning until the end of operations).”

Suburban bus routes operated by the Attica Transport Consortium are expected to run normally.
