In 2025, the Company employed a total of 40 persons with disabilities — 3 of whom were engaged as permanent employees under Section 33, and 37 under Section 35, which provides for concession arrangements and income-generating support for persons with disabilities. Of these, 19 individuals with disabilities from 5 municipalities surrounding the Company's Rayong Office received targeted assistance, including vocational promotion, income assessments, and coordination with subject-matter experts to provide occupational knowledge and guidance. As a result, the average income of supported individuals increased by 60% compared to their pre-support baseline — contributing to meaningful improvements in quality of life, greater self-reliance, reduced burden on families and society, and positioning persons with disabilities as productive contributors to household and national economic development, particularly among those of working age.

The Company also partnered with the Alumni Association of the Vocational Training and Rehabilitation Centre for the Blind to provide 13 visually impaired massage therapists offering complimentary traditional Thai massage services (focusing on the neck, shoulders, and upper back) to office-based employees at both the Bangkok and Rayong offices.

As a result of these efforts, the Company received two awards at the Outstanding Provident Fund Competition organized by the Association of Provident Fund (AOP):
- The First Runner-Up Award in the Single Fund category for provident funds in the private sector group with fund assets exceeding 1,000 million baht, receiving a trophy from the Ministry of Finance.
- The Outstanding Employer Promotion Award is a specialized outstanding award in the private sector category, receiving a trophy from the Securities and Exchange Commission (SEC).
Receiving this award demonstrates that the GC's provident fund consistently develops new benefits for employees, promotes and supports the creation of wealth and sustainable retirement savings for employees in the long term, caters to all employee groups, and aligns with the rapidly changing current economic conditions for the maximum benefit of employees.
Furthermore, to deliver personalised benefits and foster long-term employee loyalty, the Company has introduced an option for employees to receive commemorative awards for long service and retirement in the form of gold bullion or savings lottery bonds, at their discretion.
