Employment law in Asia: contracts, probation, working time and termination

The mechanics of employing someone differ more across Asia than across Europe. Termination is nearly at-will in Singapore and Hong Kong and close to impossible without cause in Japan, Korea and China; probation is unregulated in one country and capped at two months in the next; a written contract is optional in one place and mandatory within a month in another. This guide covers the rules an employer — or its EOR — must follow in the region’s main markets.

Working time and overtime

The standard week is 40 hours in China, Japan, Korea and Vietnam (Vietnam permits 48), 44 in Singapore and Hong Kong has no statutory maximum. Overtime premiums are 150 % on weekdays in most markets, rising to 200 % or 300 % on rest days and public holidays in China, Vietnam and Korea. Japan caps overtime at 45 hours a month and 360 a year in principle, with a hard ceiling of 100 hours in any month under the 2019 work-style reforms; Korea caps the total working week at 52 hours. Singapore’s Employment Act overtime rules apply only below a salary threshold, and Hong Kong has no statutory overtime rate at all. Managers are exempt from overtime in most jurisdictions, but the definition of “manager” is narrower than employers assume, particularly in Japan.

Termination and severance

The single biggest difference across the region

Hong Kong and Singapore allow termination on notice without a reason (subject to anti-discrimination and, in Singapore, wrongful-dismissal claims). Malaysia and Thailand allow it with severance. China, Japan, South Korea, Indonesia, Vietnam and the Philippines require a lawful cause — and in Japan and Korea the courts interpret cause so narrowly that dismissal of a permanent employee for performance is rarely upheld. An EOR carries the process; you make the decision, and in the cause jurisdictions you should expect a negotiated exit rather than a dismissal.

MarketNoticeCause required?Statutory severance
Hong Kong7 days minimum after probation; contractual, typically 1–3 monthsNo, subject to unlawful-dismissal protections2/3 month per year after 24 months (severance) or 5 years (long service), capped HK$390,000

Employee or contractor

Every jurisdiction here will look through a contractor agreement to the reality of the relationship: fixed hours, a single client, integration into the team, provided equipment and direction of the work all point to employment. The consequences of misclassification are back-payment of social contributions and leave in most markets, deemed employment (with the termination protections above) in Korea, the Philippines and Indonesia, and in China the double-pay penalty for the missing written contract. The practical rule: if you would manage the person as an employee, employ them — through an EOR if you have no entity.

Disputes

Labour disputes in China go first to mandatory arbitration at the local labour arbitration commission; in Korea to the Labor Relations Commission; in Japan to the labour tribunal or courts, with a fast-track mediation system; in Indonesia through bipartite negotiation, mediation and the Industrial Relations Court; in the Philippines to the NLRC; in Hong Kong to the Labour Tribunal; in Singapore to the Tripartite Alliance and the Employment Claims Tribunals. Employees win a large share of contested dismissals in the cause jurisdictions, which is why experienced employers there negotiate exits.

Frequently asked questions

Which Asian country is easiest to employ in?

Singapore and Hong Kong: written terms are simple, probation is unregulated, overtime rules are limited, and termination on notice is lawful. Contributions are also low (Hong Kong) or moderate (Singapore).

Which is hardest?

For termination, Japan and Korea, where dismissal for performance is rarely upheld. For process, mainland China, where the written-contract deadline, enumerated dismissal grounds, city-level social insurance and labour-dispatch rules all have to be right. For cost, Indonesia’s severance formula surprises most first-time employers.

Can I put someone on a long probation to keep flexibility?

Only where the law allows. China caps probation by contract length, Indonesia at three months, the Philippines at six, Vietnam by role. In Japan and Korea a probationary employee still has meaningful protection against dismissal. Thailand’s customary 119-day probation exists to end contracts before severance accrues at 120 days — lawful, but candidates know what it means.

Does an EOR protect me from termination liability?

The EOR’s entity is the employer and carries the legal process and the primary liability. The cost of a lawful exit — notice, severance, a negotiated package — is passed through to you under the service agreement. What a good EOR saves you is the procedural error that turns a lawful dismissal into an unlawful one.
