Greece's main unions on Wednesday called a 24-hour general strike to protest the government's shock closure of state broadcaster ERT.
"The ERT lockup amounts to a coup d'etat," leading union GSEE said in a statement as civil servants and sailors pledged to support the strike set for Thursday.
Journalists have already been on a rolling 24-hour strike since 0300 GMT on Wednesday against the measure, which will immediately slash nearly 2,700 jobs.
The conservative party heading Greece's coalition government insisted that a new state broadcaster will be created, branding the existing organisation too corrupt to save.
But its move has sparked uproar in the country and abroad, drawing condemnation from the Church, Greeks in the diaspora and even from the conservative party's allies in government.
