Management That Truly Pursues Employee Happiness
At Usui Manufacturing, our management is built on three core pillars: customer satisfaction, company growth, and employee happiness.
In particular, we measure employee happiness each year through an annual happiness survey and continuously make improvements based on the results.
・2014：16.1％
・2024：86.5％
One of our key strengths is our commitment to visualizing employee feedback and reflecting it in management.
Creating a Comfortable Workplace Through 3S Activities
Following a company visit in 2012, we began thoroughly implementing 3S activities—Sort, Set in Order, and Shine—throughout the company.
For us, 3S is not just about keeping the workplace clean. It has become a system that delivers tangible benefits back to our employees.
Reduced time spent searching
Improved productivity
Better equipment investment and salary improvements
Realization of a two-day weekend system
Skill Maps That Make Growth Visible
To support the growth of each employee, we use skill maps and promote multi-skilled workforce development.
This helps create an environment where new employees and female staff can also thrive.
Visualizing who can do what
Making growth visible to both the individual and the team
Enabling flexible staff assignments and easier time off
