■ Initiatives for Women's Empowerment at I.S.T.
At our company, we are constantly challenging ourselves with new research and development, with about one-third of all employees engaged in R&D and technical development. Female employees are playing active roles as leaders, and 15% of them are currently in management positions. To support the desire to balance both career and family, we have created an environment where maternity and childcare leave systems are easy to use. The childcare leave acquisition rate and the return-to-work rate for women have both been 100% over the past three years. We are also working to realize flexible work styles by introducing staggered working hours and remote work systems.
We received the top-level 'Eruboshi' (3rd stage) certification because of our high ratio of female employees, the active participation of women in management and leadership development, and the establishment of systems that support career development and transitions to regular employment.
We will continue to strive for a better workplace environment where all employees can thrive, while contributing to the local community through chemistry.
