Human rights


Challenges, Risks, and Impacts

Significant development in human rights has occurred since the United Nations proclaimed the Universal Declaration on Human Rights as a “universal” human rights framework about 70 years ago. In 2017, the Royal Government of Thailand declared its commitment to human rights as the national agenda through the development of the 4th National Human Rights Plan and the National Action Plan on Business and Human Rights. After that, the 1st National Action Plan on Business and Human Rights (NAP) for 2019-2022 was published in 2019. The 2nd National Action Plan on Business and Human Rights for 2023-2027 has been officially announced in 2023. Thaioil Group aims to respond to this national action plan and cope with the impacts of the COVID-19 pandemic and the other impacts that accelerate the changes in any aspect. In particular, the risks that may lead to human rights violations in various dimensions have been considered, for example, employment and labour practices, migrant worker and forced labour, community rights, and employee engagement and inequality that affect employee security and mentality. For these reasons, Thaioil Group has determined the action plan in accordance with the 2nd of the National Action Plan on Business and Human Rights to elevate and prioritize the prevention and protection of human rights for all stakeholders.

Commitments and Targets

Thaioil Group is committed to respect human rights in all operational areas across the value chain, as demonstrated in the Company's business operations. The Company has adopted the Human Rights Policy and the Thaioil Group Human Rights Impact Assessment and Management Procedure since 2015. Also, these policies and procedures have been consistently updated to align with the United Nations Guiding Principles on Business and Human Rights (UNGPs), The Core Conventions of the International Labor Organization (ILO), the United Nations Global Compact (UNGC), International Finance Corporation (IFC), and the National Action Plan on Business and Human Rights (NAP).

To manifest the human rights commitments across the "Thaioil Group Value Chain," Thaioil Group has developed tools and conducted Human Rights Due Diligence (HRDD) for business activities and suppliers in the value chain every three years and monitored the performance on an annual basis. The tools and approaches are aligned with the International Finance Corporation's (IFC) Guide to Human Rights Impact Assessment and Management, the UN frameworks, the National Action Plan on Business and Human Rights (NAP), and the enterprise risk management criteria. This approach has been clearly described in the Thaioil Group Human Rights Impact Assessment and Management (HRIAM) Procedure.

Thaioil Group places importance on labor rights and equality. The Company considers that the challenges, risks, and impacts from the COVID-19 pandemic, as well as the construction of the Clean Fuel Project (CFP) may lead to violations of human rights in various aspects, particularly in occupational health and safety of the workforce. To mitigate these risks, Thaioil Group has organized training, communications, and activities related to human rights for management executives and employees. These activities aim to increase the understanding of the Company's policies and practices and prevent human rights violations in its operations and value chain. Moreover, to retain talents within the organization, Thaioil Group annually considered employee compensation and remuneration to ensure competitiveness with the industry peers and Thai companies. The consideration is aligned with the Human Rights Policy in the Workplace on the Fair Treatment for Employees, the Equal Pay Policy, and the Non-discrimination and Anti-harassment Policy. Also, the Company promotes non-discrimination, the Union's Freedom of Association and Collective Bargaining, and the employment of people with disabilities, as specified by the government. With these implementations, the Company has achieved 94% of employee satisfaction in 2023.

In 2023, 75% of Thai Oil PCL’s employees are the members of the Thai Oil Refinery Workers’ Union, according to the assessment processes of all business activities, with a record of zero protests and strikes.
