Welfare Committee

“Breastfeeding Corner”

The Company places importance on respecting and promoting human rights, particularly children’s rights and the rights of mothers in the workplace. Accordingly, it has established a “Mother’s Corner” to support employee mothers in expressing and properly storing breast milk. This initiative promotes children’s rights to appropriate care, quality nutrition, and age-appropriate development, while also supporting employees’ rights to maintain a balance between family life and work.

“Children’s Corner”

Based on employee feedback received through the grievance and suggestion box, the Company found that employees with school-age children, particularly those with preschool and primary school-aged children, had concerns regarding childcare during school holidays and after school hours. These concerns arose from the lack of caregivers, children having to stay at home alone, or the need to enroll them in summer programs, resulting in additional expenses. In some cases, employees were required to take leave to pick up their children or send them to live with relatives in other provinces, which reduced family closeness and relationships.

“Educational Scholarships for Employee's Children”

The company places importance on promoting children’s rights to equal and continuous access to education, alongside improving the quality of life of employees’ families. The welfare committee is responsible for considering and proposing scholarships for employees’ children in accordance with specified criteria and conditions, in order to help reduce education expenses and support children’s learning opportunities from the basic level.
