Seoul, April 21 Samsung's unionized workers said on Friday they will bring a labour dispute with the tech giant to the state labour relations commission for arbitration.
"Despite record high earnings, the management has dismissed the unions' demands all the time, citing business difficulties," Samsung's four unions said.
"At every wage negotiation, the company unilaterally decides on a final proposal and announces it," they added, reports Yonhap news agency.
The unionized workers, which accounted for around 7.4 per cent of the total 121,000 workers, have engaged in wage negotiations with the management since late December.
The two parties have so far held 20 rounds of talks and negotiations but have not been able to iron out differences, including a union request for more than a 10 percent pay increase.
When an arbitration claim is filed at the National Labor Relations Commission, a committee will be set up to look into the dispute for 10 days to mediate between the two.
Last year, the unions had threatened to go on strike after the commission failed to bring the two parties to an agreement but did not carry it out.
Separately, Samsung Electronics' management and its workers agreed last Friday to an average 4.1 percent pay raise for the year.
The company has put on hold raises for its board members due to poor performance amid a worsening chip glut and a global slowdown.
The pay raise is lower than the 9 percent wage hike of the previous year, which was the highest in a decade, and lower than the initial demand from the workers.
Both parties hammered out the compromise, taking into consideration the external headwinds that caused the quarterly profit to plunge nearly 96 per cent in the first quarter.
