In 2023, Delta actively expanded its global production sites and capacity, and established new plants in Taiwan, Asia-Pacific, EMEA, and the Americas. In response to the expansion of R&D, engineering, and new business development in Taiwan, there was an increased of 628 people year-on-year (approximately 4.4%) in employee count. Due to the exceptional performance of smart manufacturing and the global adjustment in production capacity, the total number of employees at the end of 2023 was 81,855, a decrease of 3,829 compared to 2022(approximately 4.5%), including 34,205 professional technical and management units personnel and 47,650 operators (including production line assistants). To assist new employees in adapting to the work environment, plants in different regions have implemented retention measures, including new employee seminars, mentorship programs, professional training, and other programs to create high-quality work environments and facilities to retain talents. The overall monthly average turnover rate decreased from 2.9% in 2022 to 1.5% in 2023.

Delta is committed to adhering to international human rights conventions and local regulations in its global operations. We established the “Delta Human Rights and Employment Policy” to communicate Delta's commitment to global human rights. Delta is committed to maintaining diversity and security in the workplace environment and established the "Delta Group Non-Discrimination and Anti-Harassment Policy" in 2023 to declare Delta's commitment to the workplace environment. Delta has adopted a "zerotolerance" policy towards any form of discriminatory or harassing behavior and established the whistle-blowing system. We rigorously abide by regulations regarding reports and complaints as well as the management of unlawful infringement in the workplace, protect the equity, respect, safety needs of all relevant personnel, and take appropriate preventive, corrective, and punitive measures, and protect the rights and privacy of the parties.

Delta organizes human rights policy training every year and conducts an assessment of potential employee human rights issues across business activities at least once every three years. The scope of coverage includes Delta's own operations and joint ventures. In 2023, Delta referenced the guidelines of the United Nations to subdivide the severity of the risk assessment based on the scale, scope, and irremediability to identify the impact on employee human rights, formulate mitigation and remediation measures, and determine the priority of actions to mitigate and prevent recurrence of risks. We commenced investigations in 2023 and summarized the results and risk response measures in "2023 Human Right Due Diligence and Modern Slavery Report", which is published on the official website in accordance with the "Modern Slavery Act" of the United Kingdom.

Delta identifies human rights issues every year through internal RBA reviews and external audits, as well as internal and external grievance records. We identify potential employee human rights risks through human rights risk assessment questionnaires at least once every three years.

We take remedial and mitigation measures based on risk assessment results and implement continuous improvement to ensure the purpose of risk management. The 2023 employee human rights risk assessment coverage rate*1 was 100%. In 2023, we assessed 12 human rights issues, and identified 1 medium-risk issue (working hours) and 5 low-risk issues (prohibition of forced labor, wages and benefits, discrimination and harassment, freedom of association, and privacy) were identified. The remaining issues were almost risk-free.

Through human rights due diligence, Delta has identified several key human rights issues, such as the young labor, Discrimination and harassment, care for pregnancy and postpartum periods, as well as the employment of persons with disabilities and indigenous employees. Delta has also set specific internal goals for each of these areas.
