A foreign company often enters Korea with a small team: one country manager, a finance lead, a sales director, and a few local hires. The first wave of setup work usually focuses on incorporation, tax registration, a bank account, office space, payroll, and immigration. Then the business grows from nine employees to ten, and a new compliance item quietly becomes urgent: Korea rules of employment.

For foreign subsidiaries, Korea rules of employment are not just an employee handbook. They are a statutory HR document that must cover specific working conditions, follow employee consultation procedures, and be filed with the competent labor office once the employer reaches the relevant threshold. If the document is copied from a global template without Korea-specific terms, it can create wage, leave, disciplinary, and termination problems that are expensive to fix later.

This guide explains when Korea rules of employment are required, what they must include, how foreign subsidiaries should adopt or amend them, and how they interact with employment contracts, payroll, and company setup planning.

Why Korea Rules of Employment Matter During Company Setup

Under the Labor Standards Act, Korea regulates many employment terms as mandatory minimum standards. Article 2(1) defines an employee broadly as a person who provides labor to a business or workplace for wages, regardless of job title. The Act is therefore relevant to local managers, sales employees, engineers, administrative staff, and many other workers hired by a foreign-invested company in Korea.

The Labor Standards Act generally applies to workplaces with five or more regular employees for many core protections, including working hours and dismissal rules. A separate trigger applies to Korea rules of employment. Article 93 requires an employer that ordinarily employs ten or more workers to prepare rules of employment covering the statutory items and report them to the Minister of Employment and Labor, practically handled through the local labor office.

This ten-employee threshold catches many foreign subsidiaries at an awkward moment. The company is no longer in pure launch mode, but it may not yet have a full Korea HR function. Headquarters may assume its global employee handbook is enough. In Korea, that assumption is risky because local rules must address Korean statutory concepts such as annual paid leave, severance-style retirement benefits, working hour limits, wage payment rules, maternity and childcare protections, disciplinary procedures, and workplace safety-related obligations.

A properly drafted set of Korea rules of employment gives the subsidiary a stable HR operating framework. It also helps align the employment contract, payroll settings, approval workflows, and internal policies before disputes arise.

When Korea Rules of Employment Are Required

The key statutory rule is Article 93 of the Labor Standards Act. An employer with ten or more employees must prepare and file rules of employment. The filing obligation is not limited to Korean-owned companies. A Korean subsidiary of a US, UK, EU, Singaporean, Japanese, or other foreign parent is treated as a Korean employer once it hires employees in Korea.

The threshold is based on employees ordinarily employed by the business or workplace. For a growing foreign subsidiary, the practical question is not only how many people are on payroll today, but whether the Korean operation has reached a stable headcount of ten or more. Employers should review headcount across regular employees, fixed-term employees, and part-time employees. Independent contractors should be assessed carefully because a person labeled as a contractor may still be treated as an employee if the reality of the relationship shows employer direction, wage-like compensation, integration into the business, and limited independence.

Article 17 of the Labor Standards Act separately requires certain working conditions to be stated in writing when entering into an employment contract. These include wages, prescribed working hours, holidays, annual paid leave, and other statutory matters. This written employment contract obligation applies even before the company reaches ten employees. Once the business reaches the Article 93 threshold, the rules of employment become the broader policy document that standardizes terms across the workforce.

For example, a German software company may incorporate a Korean subsidiary in Seoul with six employees in January, add three customer success staff in April, and hire a local HR manager in June. By mid-year it may have ten employees and need Korea rules of employment. Waiting until the first labor inspection, wage claim, or disciplinary dispute is the wrong approach. The better plan is to start drafting once the hiring roadmap shows the ten-person threshold is likely within the next quarter.

What Korea Rules of Employment Must Include

Article 93 lists the core subjects that rules of employment must address. In plain English, the document should function as the Korean workplace constitution for recurring employment matters. It should be specific enough to guide managers and employees, but flexible enough to work as the company scales.

Common required or expected topics include working hours, rest periods, holidays, leave, shift arrangements, wage calculation and payment, promotion and demotion, retirement, resignation, dismissal, disciplinary measures, occupational safety and health, maternity protection, childcare-related leave, and employee welfare matters. The document should also address how bonuses, allowances, remote work, expense reimbursement, business travel, confidentiality, conflicts of interest, and data or IT usage fit into the Korean employment framework.

Wages deserve special care. Korean law distinguishes base salary, fixed allowances, variable bonuses, overtime pay, holiday work pay, unused annual leave allowance, and retirement benefits. A global template that simply says employees receive compensation according to company policy may be too vague. The rules should support payroll by explaining wage components, calculation periods, pay dates, and deduction rules. This is especially important where headquarters uses equity incentives, discretionary bonuses, or global sales commissions.

Working time is another high-risk area. Article 50 of the Labor Standards Act sets the basic working hour framework, and Article 53 governs overtime limits and agreements. The rules should explain ordinary working hours, break times, overtime approval, holiday work, night work, flexible work arrangements if used, and timekeeping expectations. Foreign managers sometimes assume salaried employees are exempt from working hour rules, but Korea does not follow the US-style exempt/non-exempt model in the same way. A local policy must be drafted around Korean law rather than copied from a US handbook.

Annual paid leave also needs Korea-specific drafting. Article 60 of the Labor Standards Act provides the statutory annual leave framework. The rules should explain accrual, use, carryover or expiration mechanics, unused leave allowance where applicable, and approval procedures. If the company wants to use annual leave promotion procedures or planned leave systems, those should be designed carefully and supported by compliant notices.

Employee Consultation and Filing Procedures

Adopting Korea rules of employment is not only a drafting exercise. Article 94 of the Labor Standards Act requires the employer to hear the opinion of a labor union representing a majority of employees, or if there is no such union, the opinion of a majority of employees. If the rules are amended in a way that is disadvantageous to employees, the employer generally needs consent from the majority union or a majority of employees.

This procedure is where foreign subsidiaries often make mistakes. Headquarters may approve a handbook internally and ask local HR to circulate it by email. That may not be enough. The Korea process should create a record showing that employees had a meaningful opportunity to review the rules, express opinions, and, where required, provide consent.

A practical process usually includes a Korean-language draft, an English summary for expatriate managers if needed, a comparison table for major policy changes, an employee briefing, a written opinion or consent collection process, and a filing package for the labor office. For a newly adopted set of rules, the company should keep evidence of circulation, meeting materials, employee representative selection if applicable, opinion forms, consent forms for disadvantageous terms, and the filing receipt.

The distinction between an ordinary adoption and a disadvantageous amendment matters. Suppose a foreign subsidiary already has generous paid sick leave in its filed rules and later tries to reduce it to align with headquarters policy. That may be a disadvantageous change requiring employee consent. Conversely, adding a clear expense reimbursement procedure may be less sensitive if it does not reduce existing employee rights. Because Article 94 issues are fact-specific, companies should not treat handbook amendments as routine administrative edits.

Article 96 of the Labor Standards Act is also important. If a rules-of-employment provision falls below statutory standards, that provision may be invalid, and the statutory standard applies instead. In practical terms, the company cannot solve a compliance issue by getting employees to sign a policy that gives them less than Korean law requires.

Aligning Korea Rules of Employment With Global HR Policies

Foreign companies usually want consistency across jurisdictions. That is sensible, but Korea rules of employment should not be a direct translation of a global handbook. The better approach is to separate global principles from local legal mechanics.

Global principles may cover anti-bribery, confidentiality, respectful workplace standards, information security, trade secrets, conflicts of interest, document retention, sanctions compliance, and whistleblowing channels. Korea-specific mechanics should cover statutory leave, wages, working hours, retirement benefits, disciplinary procedure, termination documentation, and employee consultation.

For example, a US parent may have an at-will employment clause in its standard handbook. That clause should not appear in the same way in Korea. Korean termination rules require just cause and proper procedure, and dismissals are commonly challenged before the Labor Relations Commission. A Korean rules-of-employment document should instead describe resignation, retirement, disciplinary action, ordinary dismissal, notice or payment in lieu where applicable, and internal investigation steps in a way that fits Korean law.

Data and monitoring policies also need localization. A company may use global systems for email, messaging, endpoint security, HR information, and performance tracking. Korea's Personal Information Protection Act is relevant when employee personal data is collected, transferred overseas, retained, or monitored. The rules of employment can cross-reference separate privacy notices and IT policies, but the overall HR framework should not ignore Korean privacy requirements.

Language is another practical point. Korean employees should be able to understand the binding employment rules that apply to them. Many foreign subsidiaries maintain a Korean version as the controlling local rules and an English convenience translation for headquarters and expatriate managers. If both versions exist, the company should specify which version prevails in case of inconsistency.

Practical Example: Scaling From Startup Team to Korean Subsidiary

Consider a Canadian medical device company that sets up a Korean subsidiary to manage regulatory coordination, sales, and hospital partnerships. It starts with four employees and uses short bilingual employment contracts. Within eighteen months, it grows to twelve employees, including sales, clinical support, logistics, and finance staff.

At that point, the company needs Korea rules of employment. Its highest-risk issues are not theoretical. Sales employees work irregular hours around hospital meetings. Clinical support staff occasionally handle weekend training. The finance manager processes commissions and allowances through payroll. Headquarters wants strict confidentiality and non-solicitation language. The local team expects clear annual leave rules and transparent disciplinary procedures.

A compliant project would begin by reviewing existing employment contracts, payroll components, offer letters, bonus plans, and global HR policies. The company would then draft Korea-specific rules of employment covering Article 93 subjects, harmonize inconsistent contract language, and decide whether any existing benefit will be preserved, standardized, or changed. If any change disadvantages employees, the company would plan an Article 94 consent process rather than treating the revision as a simple policy update.

The result is a Korean HR framework that supports business growth. Managers know when overtime approval is required. Employees know how leave and expenses work. Payroll can classify wage items consistently. Headquarters gets a document that protects confidentiality and compliance without importing terms that conflict with Korean law.

Practical Tips for Foreign Subsidiaries

Start before reaching ten employees. If the hiring plan shows ten employees soon, begin drafting Korea rules of employment early rather than waiting for a labor office request.
Use Article 93 as the checklist. Make sure the rules cover statutory subjects such as working hours, wages, leave, retirement, discipline, and dismissal.
Align contracts and policies. Employment contracts, offer letters, payroll codes, bonus plans, and global handbooks should not contradict the Korean rules.
Document Article 94 procedures. Keep records of employee opinions, consent where needed, briefing materials, and filing receipts.
Localize wage and working-time provisions. Korea does not simply follow US or EU classifications for exempt employees, overtime, or salary treatment.
Review benefits before reducing them. Removing or narrowing an existing benefit can trigger disadvantageous-change consent requirements.
Keep Korean and English versions controlled. If an English version is used for headquarters, state whether it is a translation and which language controls.
Connect HR setup with broader compliance. Rules of employment should coordinate with social insurance registration, payroll withholding, immigration status, workplace safety, and data privacy policies.

Conclusion

Korea rules of employment are a core part of building a durable Korean subsidiary. They move the company from ad hoc startup hiring to a structured HR system that can survive growth, audits, employee complaints, and management changes. For foreign businesses, the key is to treat the document as a Korean legal instrument, not as a translated global handbook.

The best time to prepare is before the ten-employee threshold becomes an emergency. By aligning Article 93 content, Article 94 consultation, employment contracts, payroll, and global policies, a foreign subsidiary can reduce labor risk while giving managers clear operating rules.
