HR Transformation for Southeast Asia
Since 1983, JST has helped multinationals and project-driven organizations redesign their HR function — from nationalization compliance and workforce ramp-up to zero-based restructuring and operating model design.
More than advisory — we implement
Is your HR function keeping pace with your business? JST HR Solutions partners with leadership teams to diagnose gaps, design future-state operating models, and manage change that sticks. We bring four decades of on-the-ground SEA experience — including Thai labour law, BOI compliance, immigration, and project workforce management.
Our consultants work alongside your team. We don't hand you a report and walk away.
What we do best
Nationalization & local content
Design and implement local talent development plans aligned to BOI and government investment incentive requirements. Internship and R&D partnerships, skills transfer programs, and Thai national succession planning.
Project-based workforce ramp
Mobilize teams in weeks. JST acts as Employer of Record, handling contracts, payroll, immigration, and offboarding as project phases start and end — giving you full workforce flexibility with minimal legal exposure.
Zero-based HR restructuring
Rebuild your HR function from first principles. Operating model design, org restructuring, role clarity, process reengineering, and HR technology selection — aligned to your business strategy.
HR compliance & policy design
Thai Labour Protection Act compliance, employment contract drafting, workforce policy and handbook development, and advisory on evolving local regulatory requirements including BOI workforce ratios.
Talent & performance systems
Performance management framework design, KPI architecture, succession planning, and competency models — supported by coaching and leadership development through our training programs.
HR technology & payroll setup
System selection and implementation support, payroll infrastructure setup, personal income tax and social security reporting automation — delivered alongside our managed payroll service if needed.
JST helped build Thailand's local oil & gas workforce — from the ground up, starting with Unocal in the 1980s.
When international operators first arrived in the Gulf of Thailand, their offshore workforce was overwhelmingly expatriate — engineers, drillers, safety officers, and technicians flown in from around the world. JST was there from the beginning: mobilizing, managing, and — critically — upskilling Thai nationals to replace them. Four decades later, Thailand's oil and gas workforce is predominantly Thai, trained to international standards. JST was a core architect of that shift.

Union Oil (Unocal) — first O&G concession in Thailand
Unocal awarded the first petroleum exploration concession in Thailand. Operations staffed almost entirely by expatriates — international drilling, engineering, and safety personnel.
Expat-dominant workforcePTT established — Thailand asserts energy sovereignty
Petroleum Authority of Thailand founded. Government begins pushing for increased local participation and Thai national development across all concession operators.
Nationalization mandate beginsJST Group founded — nationalization partner to Unocal and early operators
JST begins managing Thai national workforce development alongside Unocal (later Chevron), providing manpower, training coordination, and structured skills transfer for offshore operations in the Gulf of Thailand.
JST founded — nationalization partnerSystematic Thai workforce upskilling begins
JST partners with operators to train Thai nationals in offshore safety (BOSIET, HUET), technical operations, and supervisory roles — enabling direct replacement of expatriate positions with certified local talent.
OPITO / TPTI certification programsThai nationals reach supervisory and management roles
The nationalization pipeline matures. Thai engineers, HSE managers, and senior technicians — many developed through JST-managed programs — fill roles previously held exclusively by expatriates.
Local technical leadership achievedBOI mandates 70% Thai national workforce — new compliance challenge
New BOI regulations (Por.8/2568) require manufacturing companies with 100+ employees to maintain a minimum 70% Thai national workforce. JST is uniquely positioned to help clients achieve and sustain compliance through workforce design, training, and EOR management.
BOI Por.8/2568 — effective Jan 2026New BOI 2025/2026 — Thai workforce quota now mandatory
Effective January 2026, all BOI-promoted manufacturing companies must ensure Thai nationals form at least 70% of the total workforce. Non-compliance risks work permit refusals, permit renewal blocks, BOI audits, and potential revocation of tax incentives and foreign ownership rights. See our Work Permit & Visa services to understand how this affects your permits.
Building Thai talent that meets global operator requirements
Nationalization only works if local talent is trained to the same standards that international operators demand. JST designs and coordinates training pathways that take Thai nationals from entry-level to internationally certified — covering offshore safety, technical operations, HSE management, and leadership development. See our Coaching & Training programs.
Basic Offshore Safety Induction & Emergency Training
Mandatory for all Gulf of Thailand offshore workers. Covers helicopter underwater escape (HUET), sea survival, firefighting, and first aid. Valid 4 years; renewed via FOET. Required by all major operators including PTT, Chevron, and PTTEP.
Thai Dept. of Mineral Fuels — offshore access certification
All personnel working in the Gulf of Thailand must hold training from a TPTI-approved provider under Dept. of Mineral Fuels regulations. JST coordinates with accredited centres to ensure Thai nationals are fully cleared for offshore mobilisation.
Technical operations & inspection standards
API 510, API 570, API 580/581 for inspection and integrity roles. Well control certification for drilling personnel. Structured career pathways from technician to senior engineer — replacing expat technical roles with certified Thai nationals.
International Health & Safety management
NEBOSH International General Certificate for HSE officers and supervisors. Globally recognised across offshore markets. Enables Thai nationals to step into safety leadership roles previously requiring expatriate hires.
Supervisory & management development
JST runs leadership and management development programs to prepare Thai nationals for supervisory, HSE lead, and management roles — accelerating the final stage of nationalization.
Structured nationalization roadmaps
JST designs role-by-role succession plans that map current expatriate positions to a local talent pipeline — with defined timelines, training interventions, certification milestones, and BOI compliance tracking built in.
Workforce audit & gap analysis
Assess current expat-to-local ratio against BOI requirements and operator standards. Identify every position requiring nationalization and the certification gap per role.
