Greek Communist-affiliated trade union PAME on Thursday announced a rally for September 7, ahead of the opening of Thessaloniki's annual International Fair (TIF).
The union accuses ruling New Democracy of implementing measures that undermine labor rights, following the "anti-labor legacy" of leftist SYRIZA.
The rally will be held on central Aristotelous square, at 6 p.m.
Lawmakers of the main opposition SYRIZA, center-left Movement for Change, the Communist Party and anti-austerity MeRA25 left from an ongoing parliamentary debate on a omnibus bill in Parliament on Thursday, protesting over the submission of two last-minute provisions from Labor Minister Yiannis Vroutsis.
In their first post-election parliamentary debate Prime Minister Kyriakos Mitsotakis and main opposition SYRIZA leader Alexis Tsipras traded accusations of hypocrisy and populism and the debate focused on the government's appointments to the Hellenic Competition Commission and the EYP National Intelligence Service.
