Journalists of the Pula-based Glas Istre daily will begin their industrial action on Sunday, as they are denied the right to collective bargaining.
Radio 101 employees will stage a day-long warning strike on Monday as they have not received their salaries for some time.
"The crisis in the media has been lasting for years, and it has come to a head with the economic crisis," the trade union leader, Gabrijela Galic, told a news conference in Zagreb today.
HND leader Zdenko Duka said that "the time has come to call on our colleagues to show maximum solidarity with Radio 101 and Glas Istre journalists."
According to Duka, this will be the first strike in the Croatian media since 1992 when workers of the Slobodna Dalmacija daily went on strike after businessman Miroslav Kutle took over that paper, based in Split.
