Nine days in, there appears to be no end in sight to the strike. Unions are standing firm on their demand for a 6.11% raise to their salary coefficient, which they say is the lowest among public sector jobs that require college degrees. There are no talks going on right now and unions said they were waiting for the government to call them back to the negotiating table.

The strike appeared to have high support, with more than 99 percent of educators taking part in primary schools and 92 percent in secondary schools this week. They will be joined by university professors on Thursday. The labor action continues on Wednesday in Varaždin County, Istria County, Koprivnica-Križevci County, and Krapina-Zagorje County. Unions are also planning a protest in St. Mark's Square tomorrow.

"By avoiding social dialogue, by ignoring their social partners, and by ignoring the strike, the government is sending a clear message that teachers are not important to them," union leader Sanja Šprem told reporters.

Union leader Branimir Mihalinec said an offer made during mediation by Labor Minister Josip Aladrović, for a 2 percent raise to the coefficient, followed by an additional 2 percent over time, was off the table.

"Tomorrow we will send a message to the Prime Minister that we are here and our knowledge is vast. Teachers are ready to convey this vast creativity and knowledge to students, but for now they will show the Prime Minister just a glimpse of that creativity," Mihalinec said, referring to the rally.

Unions plan to march from Zagreb's main square to the seat of government and parliament in the Upper Town.
