Four large Finnish unions called on Friday for tens of thousands of their members to go on strike on Oct. 3 to protest against what they called attacks on workers' rights.
The unions said the strike was over government plans to make it easier for small companies to dismiss workers.
"The obstinacy of the right-wing government ... has not left us with any choice," the Industrial Union's chair Riku Aalto said in a statement.
Service sector union PAM, professionals' union Pro and the Finnish Electrical Workers' Union also called the 24-hour strike.
Finnish food industry workers had already announced plans to strike on Oct 3. against the government plans.
The government led by the Center Party has said the changes will end up creating more jobs as they will make small companies more willing to hire.
