First, in terms of talent development, employees participated in an average of 47 hours of education and training per year, reflecting the Company’s commitment to enhancing employees’ professional knowledge and career capabilities and to strengthening organizational competitiveness through systematic training mechanisms.

In the areas of environmental protection and occupational safety, all production sites in Taiwan and worldwide have obtained ISO 14001 Environmental Management System and ISO 45001 Occupational Health and Safety Management System certifications. This indicates that the Company has established a comprehensive EHS management framework, continuously improving process efficiency, reducing environmental impacts, and ensuring that all employees work in a safe and healthy environment. Consistent implementation across the global supply chain and manufacturing sites further demonstrates the Company’s commitment to unified management in its international operations.

At the same time, the Company has long invested in social welfare.

Diverse Employee Communication Channels

The Company values labor-management harmony and employee participation and is committed to establishing communication mechanisms that are equitable, transparent, and effective, thereby creating a workplace environment grounded in both respect and trust. All operating sites have established organizations related to employee relations in accordance with applicable laws and regulations, and labor-management meetings are held regularly. At these meetings, management representatives and employee representatives engage in two-way communication and thorough discussion on topics such as the Company's operating status, employee rights and interests, compensation and benefits, working environment, and system optimization. Items resolved at the meetings are followed up by the relevant units and announced to all concerned to ensure information transparency and effective implementation.


In addition to formal labor-management meetings, the Company has also established multiple communication and feedback channels, including internal employee newsletters, announcement platforms, suggestion mailboxes, grievance hotlines, and internal information systems, to facilitate the timely communication of Company policies and important information while also collecting employee opinions and suggestions. Matters raised by employees are responded to and followed up by designated units, and anonymous reporting channels and strict confidentiality mechanisms are provided so that employees can express their views in a safe and secure environment.


The Company also encourages each operating site to establish employee representative organizations or related committees in accordance with local regulations and practical needs, so as to promote employee participation in corporate governance and operational discussions, protect employees' labor rights and interests, and continuously improve labor conditions and the working environment. Through systematic and regularized communication practices, the Company seeks to integrate the expectations of both labor and management, build consensus, and jointly promote steady business growth and sustainable development.

Diversified Employee Communication Channels

  • Labor-Management Meetings

    Labor representatives formally elected by all employees and representatives appointed by management jointly participate. The meetings mainly serve as a platform for two-way communication and discussion on topics such as the Company's operating status, employee rights and interests, compensation and benefits, health promotion, working environment, system optimization, and important vacancies.
  • Employee Welfare Committee Meetings

    Meetings are held regularly every month in accordance with relevant laws and regulations, the Company's employee welfare rules, and the charter of the Employee Welfare Committee to formulate or revise employee welfare plans and welfare activities.
  • Employee Opinion Survey

    To understand employees' views and satisfaction regarding organizational culture, core values, sustainable management philosophy, salary and reward systems, leadership style of supervisors, and the overall office atmosphere, the Company conducts an employee opinion survey every two years as an important basis for continuously optimizing management systems and the workplace environment.

Results of the Employee Opinion Survey

The Company values employees' voices and regards employee feedback as an important basis for optimizing management systems and enhancing organizational effectiveness. To understand employees' views and level of identification with various aspects including work culture, core values, sustainable management philosophy, compensation systems, leadership and management, and the workplace environment, the Company conducts an employee opinion survey every two years and uses an integrated digital platform for questionnaire collection and analysis to ensure the objectivity and comprehensiveness of the survey.


The survey covers multiple dimensions and indicators. Results are consolidated by the Global Human Resources Division, which also convenes a cross-functional task force to review findings and plan improvements. Specific optimization measures and action plans are developed for issues of employee concern, and implementation effectiveness is tracked, forming a continuous improvement cycle of "surveyanalysis-improvement-follow-up." Through regular and institutionalized employee opinion surveys, the Company aims to enhance employee satisfaction and continue building a sustainable workplace environment characterized by open communication, mutual trust, and growth.
