Greece’s largest trade union, the General Confederation of Greek Workers (GSEE), has declared a 24-hour general strike for October 1 in protest against a government bill that would permit employees to work up to 13 hours a day for a single employer.

The GSEE is calling instead for a reduction of the standard workweek to 37.5 hours, down from 40, as well as the reinstatement of collective bargaining agreements. The strike is scheduled to coincide with parliamentary debate on the controversial bill.

The announcement was backed by a survey conducted by Metron Analysis, which found overwhelming support for shorter hours. According to the poll, 94% of workers favor reduced working time provided salaries remain unchanged, while more than half (56%) oppose the proposed 13-hour provision.

Nine in ten workers said shorter hours would benefit family and social life, while over 80% believe it would improve physical and mental health. By contrast, two-thirds of those who had worked 13-hour shifts under a single employer said it was imposed by management rather than voluntary.

The proposed legislation also includes changes to vacation time, with more than half of respondents saying their annual leave is already split into three or more periods.

With tensions rising, the strike is expected to test public sentiment over the government’s labor reforms.
