One in Eight Korean Wage Workers Is Paid Below the Legal Minimum

Roughly one in eight wage workers in South Korea earned less than the statutory hourly minimum wage last year, according to the Minimum Wage Commission’s deliberation handbook for the 2026 wage review. The shortfall was far from evenly spread: among temporary workers, about 39 percent were paid below the legal floor, and sub-minimum pay clustered in small workplaces and non-regular jobs.

A Wage Floor That Many Paychecks Never Reach

The headline ratio — one in eight — is a measure of non-compliance, not of the wage level itself. It counts employees whose actual hourly pay, once working hours are set against wages received, comes in under the rate the law requires every employer to pay. That such a large share of the workforce falls below the line underscores a long-standing gap in Korea’s labor market between the wage floor on paper and the wage floor in practice.

The concentration of the problem matters as much as its size. A 39 percent sub-minimum rate among temporary workers means the law’s protection is weakest precisely where workers have the least bargaining power. Employees of small businesses and those in non-regular positions — the groups least likely to challenge an employer or to be covered by a union — account for a disproportionate share of those paid below the minimum.

How the Floor Gets Set

The figures come from the body responsible for setting the rate. The Minimum Wage Commission, which operates under the Ministry of Employment and Labor, is made up of 27 commissioners drawn in equal parts from worker, employer, and public-interest representatives. Its calendar is fixed by statute: the labor minister must request a review of the wage by March 31 each year, the commission then has 90 days to deliver its proposal, and the finalized rate is announced by August 5 before taking effect the following January 1.

The system itself dates to the late 1980s. The Minimum Wage Act was enacted on December 31, 1986, and the wage floor began operating on January 1, 1988 — meaning Korea is now nearly four decades into the experiment of mandating a nationwide hourly minimum.

Lessons From the 2018 Surge

The compliance data land against the backdrop of Korea’s most contentious minimum-wage episode. For 2018, the commission set the hourly rate at 7,530 won, a 16.4 percent jump over the prior year and the steepest increase since 2001, when the rate had climbed 16.8 percent. The government of the day had pledged to push the minimum to 10,000 won by 2020, but it ultimately abandoned that target, conceding that the rapid rise had strained self-employed business owners and weighed on employment.

That history frames the debate the new numbers will feed. One reading holds that when the floor rises faster than small employers’ capacity to pay, the result is not higher wages across the board but a larger population of workers paid illegally below it. An alternative reading points to enforcement: a wage floor that one in eight workers does not receive suggests the penalty and inspection regime, rather than the rate, is where the system leaks.

Where the Numbers Point

For the commissioners who will set future rates, the handbook’s own data present an uncomfortable arithmetic. Every increase in the minimum wage is only as effective as the share of employers who actually pay it, and the current figures indicate that for temporary workers, compliance is closer to a coin flip weighted against them than to a guarantee. Whether the policy response leans toward restraint in future rate-setting, tougher enforcement in small workplaces, or targeted support for the employers most likely to underpay, the one-in-eight figure sets the baseline any of those approaches will be judged against.
