Comprehensive Wage System: Korea's Bundled Overtime Pay

Mobile phone plans usually come with a preset amount of data every month. Korea's comprehensive wage system works in a similar way: instead of clocking and calculating extra pay whenever overtime happens, employers bundle compensation into a single fixed package. This arrangement is not explicitly written into the Labor Standards Act; rather, the Supreme Court of Korea conditionally recognized it as an accepted practice for roles like outside sales or field travel, where accurately tracking working hours is genuinely difficult.

Because logging every single minute can be cumbersome for both the company and the worker, both sides agree on a fixed estimate ahead of time. For example, they might agree on an estimated 20 overtime hours per month and add that set allowance straight to the base salary. From the company's perspective, labor costs become predictable and payroll administration becomes much simpler.

As a result, a fixed overtime allowance appears on the monthly payslip bundled alongside the base wage. For workers, it can initially feel convenient because it guarantees a predictable overtime payout every month regardless of minor fluctuations in workload.

The trouble began when this practice spread indiscriminately into ordinary office jobs and tech roles where work hours can be precisely measured. Even though hours could easily be tracked with keycards or login logs, companies began using bundled wage contracts as a loophole to avoid paying employees for the hours they actually worked.

For example, an employment contract might bundle only 20 hours of overtime pay per month, while the company regularly assigns more than 40 hours of overtime. On payday, management refuses to pay for the surplus hours, arguing that all overtime was already included in the comprehensive wage agreement. In this way, unpaid overtime—putting in long hours without receiving fair compensation—became deeply entrenched across workplaces.

Because having staff work late or come in on weekends costs the employer nothing extra, workloads routinely balloon. This severely infringes on workers' right to rest and fuels a pervasive culture of chronic overwork.

Signing a comprehensive wage contract does not give an employer free rein to demand unlimited unpaid labor. Under a fixed-overtime agreement, whenever the statutory pay calculated from actual hours worked exceeds the fixed package, the employer must pay the difference. Furthermore, mandatory statutory caps, such as Korea's 52-hour workweek limit, remain fully in force regardless of any contract terms.

If a contract pre-packages 20 hours of overtime pay but an employee actually logs 35 overtime hours in a month, the 15 additional hours must be paid separately. If working hours can be tracked, withholding that surplus compensation qualifies as unlawful wage theft.

Moreover, the Supreme Court of Korea has established that for office workers whose hours are trackable, comprehensive wage agreements are invalid to the extent that they pay less than statutory overtime standards. Aligning compensation with actual hours worked is a core principle of labor law. By contrast, only in rare positions where tracking hours is genuinely impossible and a valid agreement was signed might additional adjustments be denied. In recent years, South Korean government guidelines and legislative proposals have continued pushing to curb the misuse of this system.
