South Korea is one of Asia’s most attractive hiring destinations for global companies, particularly for technology, engineering, manufacturing, gaming, fintech, and R&D roles. However, it is also one of the most employee-protective jurisdictions in the region. Employers who approach probation in South Korea with “trial period” assumptions often face serious legal consequences.
Unlike countries where probation offers broad termination flexibility, South Korean labor law places strict limits on dismissals—even during probation. Courts and labor authorities consistently emphasize job security, fairness, and procedural compliance. As a result, mishandling probation frequently leads to unfair dismissal rulings, reinstatement orders, back pay liabilities, and reputational damage.
This 2026 guide explains how the probation period works in South Korea, employee rights during probation, termination risks, performance management expectations, and how using an Employer of Record (EOR) in South Korea enables global companies to hire compliantly without setting up a local entity.
What Is a Probation Period Under South Korean Employment Law?
In South Korea, probation is recognized in practice but not explicitly defined under the Labor Standards Act (LSA). Instead, probation exists as a contractual evaluation period, subject to strict statutory and judicial controls.
Importantly, South Korean courts do not treat probation as a “free exit” period. Employees on probation are still considered regular employees unless explicitly classified otherwise under lawful terms.
Legal Nature of Probation in South Korea
Under South Korean employment law:
- Probation must be clearly stated in the employment contract
- Employees on probation are still protected under the Labor Standards Act
- Termination during probation requires justifiable cause
- Courts closely examine employer intent and fairness
Probation is viewed as a performance assessment phase, not a suspension of employee rights.
For companies planning to hire in South Korea, this distinction is critical.
Is Probation Mandatory Under South Korean Labour Laws?
No. South Korean labour law does not require probation periods.
However:
- If probation is used, it must be contractually clear
- Vague or implied probation clauses are often ignored by courts
- Employees may be deemed regular employees from day one
Many foreign employers mistakenly assume probation reduces dismissal risk—it does not.
Typical Probation Period Duration in South Korea
While not legally prescribed, probation periods in South Korea follow market norms. Most employers set a probation period ranging from three to six months, depending on the role and industry. During this time, employees are expected to demonstrate job performance, cultural fit, and adherence to company policies. Although probationary employees enjoy the same labor law protections as permanent staff, employers may apply more flexible evaluation and termination standards, provided due process and just cause requirements are met.
Standard Probation Length Across South Korea
Most employers use:
- 3 months – Most common across industries
- Up to 6 months – Allowed in limited cases, often scrutinized
Probation periods longer than three months are often challenged unless clearly justified.
For employers seeking the best talent in South Korea, overly long probation periods may deter candidates and raise compliance concerns.
Wage Adjustments During Probation
Under Korean law:
- Employers may reduce wages during probation
- The reduction cannot exceed 10%
- The reduced wage must still meet minimum wage standards
Improper wage reductions during probation are a frequent compliance violation for foreign employers.
Employee Rights During the Probation Period in South Korea
A major misconception is that probationary employees have limited rights. In South Korea, this is false. Employees on probation are fully protected under the Labor Standards Act and are entitled to statutory benefits, minimum wage, working hour limits, and paid leave accrual. Employers must follow lawful termination procedures even during probation, including valid justification and advance notice where applicable. Any discriminatory or unfair treatment of probationary employees can expose employers to labor disputes and legal penalties.
Statutory Rights That Apply During Probation
Employees on probation are entitled to:
- Minimum wage protections
- Working hour and overtime limits
- Paid annual leave accrual
- National pension, health insurance, employment insurance
- Protection from unfair dismissal
- Safe working conditions
All core protections apply from the first day of employment.
Probation and Unfair Dismissal Protections
Unlike some countries, South Korea does not allow easy termination during probation.
Courts require:
- Objective, reasonable grounds for dismissal
- Evidence of performance deficiencies
- Fair and transparent evaluation standards
Even during probation, dismissal without just cause is illegal.
Termination During the Probation Period in South Korea
Termination during probation is one of the highest-risk employment actions in South Korea. Employers must demonstrate just cause, even when an employee has not yet completed the probation period. Poor performance alone is insufficient unless it is well-documented, objectively evaluated, and the employee has been given a fair opportunity to improve. Failure to follow due process—such as providing notice, explanation, and evidence—can result in wrongful termination claims and reinstatement orders from labor authorities.
Can Employers Terminate During Probation?
Yes—but only if:
- There is justifiable cause
- Performance standards were communicated upfront
- The evaluation process was fair and documented
Subjective dissatisfaction is not sufficient grounds for dismissal.
Notice and Procedural Requirements
Employers must:
- Provide at least 30 days’ notice, or
- Pay 30 days’ wages in lieu of notice
Failure to comply often results in unfair dismissal rulings.
Common Employer Mistakes That Lead to Unfair Dismissal Claims
Frequent errors include:
- No written performance standards
- Inconsistent evaluations
- Abrupt termination without warnings
- Treating probation as “at-will”
South Korean labor courts frequently order reinstatement with back pay.
Managing Performance During Probation in South Korea
Given the strict dismissal standards, probation must be structured carefully. Employers should establish clear performance expectations, measurable evaluation criteria, and documented review timelines from the outset. Regular feedback sessions and written performance records are critical to demonstrate fairness and transparency. A well-managed probation process not only supports employee development but also strengthens the employer’s legal position if termination becomes necessary.
Using Probation as a Performance Management Framework
Best-practice employers:
- Define clear job expectations
- Set measurable evaluation criteria
- Conduct regular feedback sessions
- Document performance discussions
Performance management is essential—not optional—in South Korea.
Confirming or Ending Employment After Probation
At the end of probation:
- Employment should be confirmed formally, or
- Lawful termination must occur with notice and justification
Automatic confirmation without review weakens future termination defenses.
Probation Risks for Global Companies Hiring in South Korea
South Korea presents unique challenges for international employers. Strict labor protections, strong employee rights, and a high burden of proof in termination cases increase compliance risk during probation. Cultural expectations around job security and fair treatment further complicate performance management for foreign companies. Without localized HR expertise, global employers may unintentionally violate labor laws, leading to disputes, penalties, or mandatory employee reinstatement.
Why International Employers Struggle With Korean Probation Laws
Key issues include:
- Underestimating employee protections
- Applying Western probation assumptions
- Lack of Korean-language documentation
- Cultural differences in feedback delivery
Courts heavily favor employees when procedures are unclear.

Using an Employer of Record in South Korea allows companies to:
- Hire legally without entity registration
- Use compliant Korean employment contracts
- Structure lawful probation clauses
- Manage performance documentation
- Execute compliant terminations
