As Thailand transitions into an aged society, retirement policy and workplace protections for older workers have come into sharper focus. With public sentiment increasingly open to working beyond the traditional retirement age, questions about employee rights and employer obligations are more relevant than ever. In October 2025, Prime Minister Anutin Charnvirakul proposed increasing the statutory retirement age to 65 for government officers, citing Thailand’s aged-society status and the potential social and economic benefits of longer working lives. While academics and stakeholders have raised concerns about systemic impacts, public opinion remains divided, with many workers signaling a willingness to continue working beyond the current norm. Against this backdrop, it’s worth revisiting what the Labor Protection Act B.E. 2541 (1998) (LPA) requires in regard to retirement and severance pay. This article explains the current legal landscape under the LPA, with a focus on retirement and severance pay for employees over 60, recent judicial developments, and practical options for structuring postretirement engagements. Retirement as Termination Under the LPA Under the LPA, retirement—whether set by agreement between employer and employee or unilaterally stipulated by the employer—is deemed a termination of employment. As a result, employees who retire under such terms are entitled to severance pay. The law also adds a default rule: if there is no agreed or prescribed retirement age, or if the prescribed retirement age exceeds 60, an employee aged 60 or older may declare an intention to retire. The declaration takes effect 30 days after notice, and the employer must pay severance accordingly. In short, retirement triggered by agreement, the employer’s work rules, or an employee’s valid notice is treated as a termination, and statutory severance pay is owed. Hiring or Rehiring Employees Over 60 Practical issues arise when an employer’s work rules set a retirement age that does not

The Thai Arbitration Institute (TAI), a division of Thailand’s Office of the Judiciary, has taken a step toward harmonizing the tools available for dispute resolution. On August 8, 2025, the institute formally launched the TAI Mediation Center (TAI-MC). Although the amendments to TAI’s Arbitration Rules that will govern the TAI-MC have not yet been finalized, the framework now under consideration suggests that TAI is positioning itself to become a more attractive venue for commercial dispute resolution. In the regime contemplated under the current version of the amendments, TAI proceedings will adopt an “arbitration-annexed mediation” mechanism—commonly termed the “Med-Arb” model—while preserving the procedural safeguards indispensable to arbitral neutrality. Mediation will be entrusted to a separate, dedicated mediator appointed under the TAI-MC who is precluded from serving on the arbitral tribunal in the same matter. By clearly separating the functions of mediator and arbitrator, the institute eliminates any risk that confidential information disclosed during mediation could influence the adjudicatory outcome if the parties do not settle. Only when all parties subsequently make a request may that same mediator assume arbitral duties in the case. The parties will retain substantial autonomy in selecting the mediator. They may either designate a mediator by mutual consent or invite the TAI-MC to appoint one from its authorized panel. TAI has announced its intention to curate that panel with particular emphasis on commercial expertise and cross-cultural negotiation skills, supplemented by ongoing professional training. Where the parties cannot agree on remuneration, the mediator’s fee will default to a tariff comparable to the TAI-MC’s cost schedule, which under the current version of the amendments will be approximately THB 45,000 for disputes in which the aggregate claims do not exceed THB 10 million, with incremental increases tied to higher claim values. This predictable cost matrix is aimed at enhancing

Under Thai law, authorized directors stand as a company’s mind and will and, as such, may incur personal criminal liability for acts or omissions committed in the course of company business. When allegations surface, directors must be prepared for the practical reality that, before guilt or innocence is ever adjudicated, they could be deprived of liberty unless bail release is promptly achieved through the competent legal authority. When Bail Can Be Granted Two procedural moments trigger the need to consider bail. The first arises during the investigative phase, when a claim is lodged against a director with the competent law enforcement authorities. Upon receipt of a complaint, the assigned inquiry officer summons the director for questioning, compiles evidence, and ultimately forwards a prosecution or nonprosecution recommendation to the public prosecutor. Although the public prosecutor retains ultimate discretion to indict an accused director, the police or prosecutor may conclude that pretrial detention is necessary and may therefore apply to the court for an order to hold the director in court custody. The second moment occurs after a criminal case is filed directly with the court. This occurs once a court accepts a criminal case filed by a prosecutor against a director or, alternatively, when the court accepts a case filed by an individual for trial. For cases filed by individuals, the plaintiff presents prima facie evidence at the preliminary hearing, and the court will accept the complaint if it finds sufficient grounds, thereby conferring upon the director the status of a criminal defendant. Upon acceptance of the criminal case, the court then has the inherent authority to order custody pending trial unless the defendant secures bail release. Procedural Considerations Experienced litigants typically prepare bail security in advance and submit a bail petition at the earliest possible time. While there are
