Thailand Labor Dispatch, EOR & Employment Compliance

EOR is not a statutory concept in Thailand but a service arrangement in commercial practice. The core issues to focus on in practice are: who actually manages daily work, who determines salary and position, who provides the workplace, who conducts performance evaluations, and whether the employer information on employee permits and tax and social security documents is consistent with reality. If the EOR service provider only provides personnel agency and nominal employment, while the Chinese enterprise directly manages personnel, finances, assets, and business operations, the actual employing party may still be identified as the employer or co-employer in labor disputes, immigration compliance, tax, and social security audits. It is advisable to have legal counsel review the consistency between agreement terms and actual employment arrangements before adopting the EOR model.

Thai labor protection and labor courts tend to determine employment relationships from a substantive perspective in practice, rather than based solely on contract text or nominal employer status. For factory, engineering site, or service outsourcing scenarios, if the actual employing enterprise directly schedules shifts, arranges overtime, approves leave, conducts evaluations, or issues substantive management directives, the formal arrangement of third-party dispatch or outsourcing agreements may not fully insulate the actual employing party from responsibility. It is advisable to clearly specify the rights and obligations of all parties in dispatch and outsourcing agreements, maintain consistency between contractual provisions and actual management in practice, and retain management records as evidence.

Under the Thai Labour Protection Act, enterprises with 10 or more employees are generally required to prepare Thai-language work regulations and display them in the workplace. Even for smaller headcounts, it is advisable for enterprises to prepare a basic employee handbook or work regulations, with content potentially including: working hours, rest and overtime systems, leave and holiday provisions, disciplinary procedures and grievance mechanisms, occupational safety and health regulations, wage payment, and social security benefits. For Chinese-invested enterprises, the employee handbook should be prepared in Thai (Chinese or English versions may serve as supplementary reference) and acknowledged by employees with signed confirmation. In labor disputes, employee handbooks with acknowledgment records and supporting policy documents are significant for the enterprise's evidentiary and defense purposes.

Thai labor law does not establish separate termination rules for the probationary period; the level of protection for probationary employees under the Labour Protection Act is not substantively different from that for regular employees. In practice, terminating a probationary employee still requires attention to: the probationary period provisions in the employment contract, whether clear evaluation standards and records exist, whether written communication or warnings have been issued regarding performance issues, and whether notice period or compensation provisions are complied with. It is advisable to establish a probationary employee evaluation system from the outset, retaining written evaluation records and communication documents. For terminations involving sensitive positions or potentially triggering disputes, it is advisable to have legal counsel review documents before issuing the termination notice to avoid amplifying risks due to procedural deficiencies.

The prerequisite for foreign employees to lawfully work in Thailand is that the employer, position, and work location recorded on the work permit are consistent with reality. Foreign employees working through EOR or dispatch arrangements need to pay particular attention to: whether the employer name on the work permit is consistent with the entity actually paying salary and reporting social security, whether the work location matches the office or site address recorded on the permit, whether the position description covers the actual work performed, and whether the visa type matches the purpose of work and residence. For cross-province or engineering site arrangements, if the work location exceeds the scope permitted by the permit, advance changes or additional registrations may be required. It is advisable to periodically review the consistency between foreign personnel employment documents and actual circumstances, and to consult legal counsel on handling methods before changes occur.

The typical priority for labor dispute handling is: secure facts and evidence > assess legal risks and commercial impact > choose negotiation, mediation, compensation, disciplinary action, or litigation pathways. In practice, attention should be paid to: electronic evidence (such as WeChat, email, system records) needs to be properly preserved and provided in readable format; written warnings and termination notices should be in Thai and follow legally prescribed or contractually agreed procedures; for cases involving multiple employees or sensitive positions, collective impact and public opinion risks should be assessed in advance; avoid contacting employees alone after a dispute arises or making verbal statements that could be interpreted as improper commitments. It is advisable to develop a dispute response strategy with legal counsel assistance and to establish institutional and evidentiary documentation proactively to reduce the probability of dispute escalation.
