AI Adoption Is Growing Among Thailand’s Workforce

2026 survey findings indicate that Thai professionals are increasingly embracing AI, with the technology becoming part of everyday work processes.

According to the Ipsos AI Monitor 2026, 80% of surveyed Thai workers said AI helped them save time at work, while 65% expect AI to change how they perform their current jobs within the next five years.

Key Takeaway: AI is no longer simply an experimental tool. It is increasingly becoming a practical productivity tool used in day-to-day work.

At a Glance

  • 80% of surveyed Thai workers said AI helps them save time at work
  • 65% expect AI to change how they work within five years
  • Organizations should prepare their processes and data for AI adoption

1) Recruitment and Candidate Selection

Recruitment is one of the most data-intensive and time-consuming HR processes. AI can support multiple stages of the recruitment workflow by reducing repetitive administrative tasks.

AI can serve as an HR assistant throughout the recruitment process, but it should not replace human judgment in final hiring decisions.
  • Draft and refine job descriptions
  • Summarize information from résumés
  • Group and compare candidate qualifications
  • Prepare interview questions
  • Summarize interview information

2) Employee Support and HR Services

HR teams in many organizations answer the same employee questions repeatedly—for example, remaining annual leave balances, required documents for sick leave, payroll dates, and available employee benefits.

AI can function as an HR Assistant, enabling employees to access basic information and answers when needed. This allows HR professionals to devote more time to analysis, employee management, and decision-making.

Important Consideration: AI responses should be grounded in accurate company policies and approved internal information to reduce the risk of answers that conflict with actual requirements.

3) Workforce Data Analytics

HR functions manage significant volumes of data, including employee records, attendance, leave, overtime, payroll, and performance data. In many organizations, however, these datasets remain fragmented.

When data is structured and managed systematically, AI can help identify trends and anomalies, enabling HR to spend less time producing reports and more time interpreting data and generating business insights.

Examples of Data AI Can Analyze

  • Employee turnover
  • Absenteeism
  • Unusual increases in overtime
  • Workforce costs

Benefits for Management

  • Identify workforce cost trends
  • Compare data across departments
  • Detect anomalies more quickly
  • Support data-driven decision-making

4) Payroll and Payroll Data Validation

Payroll is another area where AI can add value, particularly in validating payroll data before payments are finalized.

AI does not necessarily need to perform the entire payroll calculation. Instead, it can act as a validation assistant, flagging unusual transactions or data points for HR review.

Examples of Potential Anomalies

  • Unusual increases or decreases in salary
  • Overtime significantly above normal levels
  • Working days inconsistent with payroll amounts
  • Employees with missing attendance records
  • Unusual deduction items

Future Payroll Workflow

Payroll System → AI Validation → HR Review → Approval → Payroll Payment

This approach can reduce manual checking time and allow HR teams to focus their attention on higher-risk or exceptional items.

5) Workforce Planning

AI can help HR analyze historical workforce data to support workforce planning and model potential future scenarios.

Questions AI Can Help Analyze

  • If sales increase by 20%, how many additional employees may be required?
  • Which departments have unusually high workforce costs?
  • What would be the impact of an increase in employee turnover?

Data to Include in the Analysis

  • Headcount
  • Sales and revenue
  • Labor costs and overtime
  • Employee turnover
  • New hires

AI Is Not Replacing HR—It Is Transforming the Role of HR

What we are seeing in 2026 is not the wholesale replacement of HR by AI. Instead, AI is reducing time spent on routine tasks so HR professionals can focus more on work that requires analytical thinking, communication, judgment, and decision-making.

Where AI Performs Well

  • Data analysis
  • Report summarization
  • Anomaly detection
  • Answering repetitive questions

Responsibilities That Still Require HR Oversight

  • Employee selection and people management
  • Performance evaluation
  • Salary review decisions
  • Promotion decisions
  • People-related decisions
Key Principle: AI should support analysis and provide information, while decisions that materially affect employees should remain subject to human review and accountability.

What SMEs Should Prepare Before Adopting AI in HR

For small and medium-sized businesses, adopting AI does not require an immediate investment in a large or complex system. A more important first step is to ensure that core HR and payroll data is well structured and properly managed.

4 Areas SMEs Should Prepare

  • Standardize employee data, including employee IDs, departments, positions, start dates, and salaries.
  • Reduce fragmented data across Excel spreadsheets, payroll systems, and separate files.
  • Define data access permissions, particularly for payroll and personal data.
  • Use AI as an assistant, not the final decision-maker, especially for salary decisions, performance evaluations, promotions, and termination decisions.

The quality of AI analysis ultimately depends on the quality of the underlying data. If payroll data is inaccurate, AI can quickly produce analysis based on incorrect information. Conversely, when an organization maintains structured, accurate, and traceable data, AI can be integrated and scaled more effectively.

From Excel-Based HR to Data-Driven HR

Traditional Approach AI-Enabled Approach
Manual data collection Systematic data consolidation and analysis
Manual report review AI-assisted anomaly detection
Repeatedly answering routine questions AI Assistant handles basic inquiries
Significant time spent on routine tasks More time for strategic HR activities

Conclusion: The Future of HR Is “People + AI”

AI is unlikely to replace the HR function entirely. Instead, it will reduce routine workloads and give HR professionals more capacity for data analysis, people management, and strategic decision-making.

For SMEs, the starting point may not be selecting the most sophisticated AI solution. It is ensuring that HR and payroll data is accurate, structured, and traceable.

The future of HR may therefore not be “people or AI”
but rather “people + AI”—with AI supporting data-intensive and repetitive work while HR focuses on areas where human capabilities remain essential: understanding people and making business decisions.
