The main striking committee of the Independent Union of Secondary School Employees made the decision to stop the strike based on a poll conducted among its members.
The turnout for the strike was already low on Thursday and according to data from the Ministry of Science, Education and Sports, only 26% of secondary school teachers were striking on Thursday but they decided to continue the strike until the end of the day on Friday.
Union leader Branimir Mihalinec told Hina that the union would direct its efforts towards the next government.
"We are not giving up on our demands, a raise of 4% is what we will ask of the next government as well," said Mihalinec.
He said that the unions expected teachers' salaries to be increased in April 2016, when the next government would have a budget for that year.
The national union of workers in the system of social welfare on Friday staged a day-long strike of solidarity with teachers in social care institutions and social services. Its representatives said that employees in social care institutions did only the most necessary work, providing care for their clients, and that social services did not work as usual with their clients but had one or more on-duty employees who were not on strike or were not union members.
The union said that it had demanded an 8% salary increase but the government offered them only a "general letter of intent", similar to the one given to teachers' unions.
The union said that in case no agreement was reached with the government, it would organise a strike on October 12.
Assistant Social Policy and Youth Minister Iva Prpic told Hina that information from the ground showed that work with clients was normal insocial care institutions and social services, that duty hours had been introduced in social care institutions and that employees in social services who were on duty or not on strike received clients.
"We are not denying the legitimacy of the solidarity strike, but the ministry yesterday sent instructions on which services had to be provided during the strike and that it being honoured," Prpic said, expressing hope that the best solution would be found in the coming conciliation procedure.
