Industrial union members started the first of six days of strikes across Finland on Tuesday.
The Industrial Union announced that the strike would go ahead on Sunday, after negotiations with employer group Technology Industries of Finland did not produce results. Efforts to resolve issues during mediations on Monday were also unsuccessful.
According to Trade Union Pro, there are still a number of unanswered questions regarding collective agreements. Among other things, agreement has not yet been reached regarding salaries.
The unions are seeking an across-the-board 10 percent pay rise, but employers' representatives say that the economy cannot support such increases.
Tuesday's one-day strike involved union members from more than a dozen technology sector companies.
It will be followed by another one-day strike on Wednesday. There are plans for more strikes on 9-12 December.
