Management systems and risk identification 

WNC headquarters and its major production sites in Taiwan, China, and Vietnam have implemented the ISO 45001 Occupational Health and Safety Management System and obtained third-party verification. All certification documents remained valid throughout the reporting period and covered 100% of workers across operating sites. WNC continues to promote the standardization of occupational safety and health systems across all sites, while regularly reviewing the operation of these systems to prevent occupational disease and injury and promote employees’ physical and mental well-being. In 2025, no major occupational accidents occurred at any sites. 

To continuously lower occupational health and safety risks, WNC has established a hazard identification and risk assessment procedure to systematically identify risks in the following areas: physical, chemical, ergonomic, biological, social and mental, and others. EHS coordinators are responsible for carrying out related tasks and completing professional training for ISO 45001 and ISO 14001 internal audits to strengthen risk identification and management capabilities. Each unit conducts regular risk identification annually, or on an ad hoc basis in response to operational changes, occupational injuries, near-miss events, or hazard reports. Risk levels are assessed through matrix analysis based on likelihood, severity, and frequency. For high-risk operations, corresponding control measures and targets are established and tracked on a monthly basis. 

Risk identification process

Incident Investigation and occupational accidents

Taiwan sites perform event investigation and analyses for near misses, abnormalities, injuries, and major accidents in accordance with an Accident Investigation Management Procedure and formulate measures to prevent the re-occurrence of incidents and conduct inventory and improvement activities. In addition, we adopt the 5 Why methodology, FMEA (Failure Mode and Effect Analysis) and domino analysis methods to conduct a more in-depth review and discussion of the root causes of accidents. Following these reviews, we standardize specifications and strengthen fool-proofing mechanisms to mitigate risks at the source. To enhance investigation efficiency and root-cause analysis capabilities, WNC launched a digitized incident investigation and approval system in 2023. This system was also expanded to China and Vietnam sites in 2024, and to Mexico in 2025. 

In 2025, WNC recorded 11 lost-time injury cases. All were physical hazards, mainly categorized as “struck by/caught in/rolled into/cut or abrasion injuries” and “falls/collisions.”  There were no disabling injuries reported among non-employees, nor incidents resulting in permanent disability or death due to occupational injuries.  Each incident has been investigated and analyzed. Responsible units have developed appropriate improvement and preventive measures in response to the increase in the number of employees and the changing environment to reduce operational risks for workers.

Equitable Workplace

Professional medical services and employee health check 

All WNC sites employ nurses with past clinical experience in internal medicine, surgery, obstetrics and gynecology, pediatrics, and intensive care medicine. The facility nurses compile analyses of employees’ health issues, perform personal health hierarchical management, and plan annual health care and promotion activities accordingly to assist employees in enhancing their health awareness. At our Taiwan sites, we implement a health classification system (Grades A to E) for employees. Based on these classifications, we conduct regular health tracking, security guard education, plant doctor consultation or outpatient and emergency re-examination. In 2025, 864 medical consultations were conducted by company physicians, and the tracking rate at the Taiwan, China, and Vietnam sites reached 100%. 

WNC’s Taiwan sites hold general and specific health examinations every year and offer occupational medicine specialists' on-site health services. Annual health check-up attendance rates reach as high as 99%. WNC’s annual health examinations for employees at Taiwan sites begin in June each year. In 2023, WNC upgraded the examinations and added new examination items such as abdominal ultrasound, glycated hemoglobin testing, and alpha-fetoprotein testing. We also provide personal health consultation to help assess employees health condition and whether their health is suited for the job duties they are handling. 

After the 2025 employee health examination was completed, the follow-up completion rate for employees with moderate to severe health abnormalities was 100%. Employees’ personal health information is kept confidential to protect their personal data and privacy. In China and Vietnam, apart from a general health check, WNC also provides regular occupational and special health check items to employees with potential occupational disease hazards in accordance with local regulations. In Mexico, examination items include items related to respiratory and hearing protection, blood lead level monitoring, and the prevention of musculoskeletal injuries. 

Health promotion activities

Employees' health risks are primarily concentrated in metabolic syndrome-related indicators. In 2025, WNC launched the "Join the Vitality Program – Level Up Your Health" fat-loss initiative, which combined a fitness app, InBody body composition testing, online nutrition and exercise courses, and community interaction to engage employees in fat reduction. A total of 799 employees participated, of whom 334 (71.2%) successfully reduced body fat by 3% or more.

Preventive care

Since 2016, WNC has allocated an annual budget to promote influenza prevention and control, offering free influenza vaccination programs for all employees. In 2025, employees received a total of 2,461 flu vaccine doses, achieving a vaccination rate of 42.18%. We also subsidize MMR and hepatitis A vaccinations for employees traveling on overseas business trips. At our Mexico site, we provide chronic disease and cancer screenings alongside a vaccination program offering influenza, COVID-19, measles, and streptococcus pneumoniae vaccines. To date, a total of 513 vaccinations have been administered. 

 

 

 

Emergency care system

All WNC’s sites across the globe implement an emergency care system. At our Taiwan sites, WNC provides a 24-hour facility nurse hotline, optimizes emergency staffing, and conducts regular first-responder training. We have also installed AEDs, and inspect them biannually. Hsinchu sites have signed an emergency ambulance contract with the Hsinchu Science Park Clinic, ensuring immediate medical support when needed. Our Vietnam and Nanjing sites have also installed AEDs while the Mexico site conducts regular emergency response training.

Mental health resources

WNC’s Taiwan sites launched an employee assistance program (EAP) in collaboration with external consulting agencies to develop a dedicated mobile app. Operating under strict confidentiality and with zero impact on work conditions or benefits, the program provides two-stage services: In the first stage, colleagues’ concerns are listened to for free and without time limits. In 2025, 17 employees utilized this service. In the second stage, professional consultants offer consultation services in six areas: legal, mental health, nutrition, work issues, finance, and long-term care. Every employee is entitled to three hours of free sessions annually. In 2025, 95 employees used these services, including 43 legal consultations, and 39 mental health counseling sessions. The Mexico site also promoted its EAP by distributing a service card to employees. More than 150 EAP-related online seminars were held throughout the year.

Contractor management

WNC has established contractor ESH management procedures, requiring contractors to sign a Commitment to Work Safety for Contractors in WNC Plants and a Construction Safety Commitment Agreement before in-plant operations. Contractors are also required to participate in training sessions on in-plant hazards. In 2025, 2,582 participants from 393 contractors completed the training across WNC’s Taiwan sites while 3,046 participants from 28 contractors completed the training at the Kunshan site. Once in-plant operations are approved, contractors must attend a toolbox meeting and confirm operational details with the responsible managers, and then proceed under continuous supervision.

WNC reviews contractors and categorizes them as A, B, and C grades annually. Guidance or replacement of contractors is executed according to review results. We have also introduced unscheduled construction evaluations for new contractors and clearly defined the contractor evaluation items, scoring standards and calculation formulas to ensure standardized assessments. In 2025, we completed evaluations for six facility constructors. In addition, we have established a dedicated checklist for higher-risk operations including hot work, roofing, elevated, and restricted operations, to ensure that contractors adhere to the safety standards throughout their work.

Apart from their designated contact persons, contractors can also communicate with WNC on matters such as work safety and health management via coordination meetings, toolbox meetings, hazard awareness training, vendor performance review, and on-site inspections. For routine on-site contractors, including security, catering, and cleaning staff, our general contractor agreement stipulates full compliance with the relevant provisions of the WNC. Contractors are also required to complete the Supplier Integrity Commitment, the Supplier ESG Questionnaire, and the Supplier Commitment to Sustainability Declaration before the effective date. The goal is to elevate their awareness of labor rights, integrity and OSH.
