Korean workers down tools more often than their counterparts in any other major economy as labor relations are chronically bad.

According to a report by the Korea Labor Institute on Monday, strikes in Korea cost businesses 2.03 million lost workdays in 2016. The number was derived by multiplying the number of striking workers by the number of days they downed tools.

That means an average of 5,600 workers went on strike every day. The KLI compared the figures to International Labor Organization data and found that Korea suffered the largest number of lost workdays among the world's nine major economies.

In Japan, only 3,000 workdays were lost in 2016, which is just 0.14 percent of Korea's.
