IR Presentations
Seoul Semiconductor provides timely and regular disclosures to ensure transparent communication of key management information to stakeholders.
Seoul Semiconductor places the utmost priority on the safety and health of its employees and practices systematic occupational safety and health management.
We strengthen cooperative safety initiatives, improve working environments, and operate health management programs to ensure a healthy and safe workplace for all employees. In addition, we enhance chemical management systems to proactively identify and control workplace hazards.
Going forward, Seoul Semiconductor will continue to comply fully with occupational safety and health laws and regulations, while working with our partners to promote a strong safety culture.
Seoul Semiconductor conducts the safety environment diagnosis for all production sites and in-house partners on a regular basis through consulting with specialized companies in the safety, environment, energy, and health sectors. Participating in the “Safety and Health Coexistence Cooperation Program” organized by the Ministry of Labor, we provide safety and health support and training to our partners on a regular basis, and have achieved Grade A in 2015 in recognition for our contribution. On the other hand, we map and index the risks of all business sites to use them as a measure of risk management.
Seoul Semiconductor operates annual employee health checkups and various health promotion programs for employees’ health management. A professional health doctor supports health consultation to high-risk groups with four major diseases (hypertension, diabetes, hyperlipidemia, and liver disease) for thorough aftercare. We also investigated job stress by task to intensively manage the high stress group.
In addition, we installed an automatic ventricular defibrillator in case of an emergency and selected emergency rescue personnel for each floor to provide CPR training. We are also making efforts to improve the working environment of our employees. We measure the working environment and improve the working environment twice a year. Seoul Semiconductor will continue to carry out various health promotion and working environment improvement activities.
Seoul Semiconductor operates OHC (Our healthcare committee) through collaboration with domestic and international experts to improve the company's health management index and to enhance the diagnostic / prophylactic assessment of working environment above legal level and management level. In addition, we operate an OHC room equipped with body composition analyzers, blood glucose meters, and blood pressure devices to help prevent and manage chronic diseases of SSC / SVC employees and employees of internal partners.
Seoul Semiconductor has introduced a pre-environmental safety review system to review the risks beforehand on all substances used in the workplace. All chemicals used in our company cannot be used without a pre-risk review. All chemical handling equipment must go through the process of installation inspection, minimizing the risk that may occur. In addition, we are strengthening monitoring and conducting emergency response and training on a regular basis to prevent accidents related to chemicals.
Seoul Semiconductor is committed to ensuring sustainability across its entire supply chain and practices responsible management in line with global standards. To this end, we have established and operate the Seoul Semiconductor Supplier Code of Conduct. This Code of Conduct is based on global guidelines such as the UN Universal Declaration of Human Rights, the UN Guiding Principles on Business and Human Rights, and the RBA Code of Conduct, and serves as the standard for supply chain sustainability management.
We require mandatory agreements with our major partners regarding compliance with the Code of Conduct, and we continuously monitor adherence through new vendor assessments, regular evaluations, and supply chain risk reviews. Updates to global standards are also reflected in our Code, ensuring that our partners are supported in fulfilling their social and environmental responsibilities while practicing ethical business conduct.
Seoul Semiconductor recognizes the importance of selecting and monitoring suppliers to ensure sustainable management. Strict regulations are applied to Seoul Semiconductor’s suppliers to avoid importing minerals produced in conflict areas (especially the Democratic Republic of Congo). The regulations on the selection and monitoring of these suppliers are defined as external purchase policies and are constantly being revised
As part of economic sanctions to eradicate social issues such as infringements upon personal rights, exploitation of child labor and sexual assault in African conflict areas (10 countries including DR Congo), countries around developed countries have designated four major minerals (3TG: tin, tungsten, tantalum, and gold) that are mined in these regions as conflict minerals, and prohibit companies from using conflict minerals to prevent mining funds from flowing into military funds of rebels.
Seoul Semiconductor practices Sharing Management through diverse social contribution activities to realize our vision of “A Better World Through Light.”
Our initiatives include supporting underprivileged communities, sponsoring overseas child partnerships and emergency relief programs, providing scholarships for future talent development, encouraging employee talent donation activities, and supporting public-interest organizations. Through these efforts, we are fulfilling our social responsibility in various ways.
Going forward, Seoul Semiconductor will continue to share the company’s achievements with society, striving to create a sustainable community that grows together.
