Health Management

Basic Approach

The NGK Group strives to promote employees’ health through the NGK Group Health Declaration: “Developing dynamic, people-friendly work environments and a health-conscious corporate culture.”

Health Management Promotion System

Medical professionals, such as Chief industrial physicians and industrial health nurses, and the health management secretariat collaborate with the labor union and the health insurance association to promote health management at NGK. This is overseen by the director responsible for the Human Resources Dept.

Initiatives to Shorten Total Hours Worked

Reducing Long Work Hours

In July 2016, we lowered the maximum amount of overtime work to 70 hours per month (with an upper limit of 300 hours per half-year). To this end, employees are, as a rule, not allowed to work for more than seven days straight and are not allowed to do overtime on their twice-a-week refresh days. If either of these are necessary, they must get permission from their bosses beforehand. To prevent employees from working excessively long hours, there must be an interval period of at least 10 hours between shifts of late-night work.
In FY2021, there were nine cases of overtime work exceeding the company’s upper limit, but no cases which violated legal regulations.

Response to Increase in Overtime Work

Every year, NGK discloses actual working hours and leave taken to the labor union. We then exchange ideas and discuss what measures to take.
If it appears that the amount of overtime worked is going to exceed 45 hours, we will first hold a labor-management meeting to determine the reason for the increase in overtime, then implement measures such as evening out work periods and workloads or adding additional workers.
Whenever it is determined that employees are actually working long hours, we discuss countermeasures for each worksite with the labor union.
For employees temporarily stationed overseas, as soon as it is discovered that they are working long hours, they are required to submit a written reason and undergo a health examination. This not only serves to maintain the health of employees temporarily stationed overseas, but allows us to determine the cause of the long working hours from the written report, and implement countermeasures to correct the situation.

Following Up on Employees Working Long Hours

NGK provides employees working long hours, including non-regular and part-time employees, with ongoing opportunities to meet with industrial physicians for health consultations and exams. The results are reported at monthly Safety and Health Committee meetings at each worksite to thoroughly promote the reduction of overtime work.

Promoting Activities Supporting Mental and Physical Health

Four Types of Care for Mental Health

We facilitate the widespread implementation of ongoing mental and physical health promotion activities, centering on the four types of care for mental health promoted by the Ministry of Health, Labour and Welfare (MHLW).
In FY2021, we carried out stress checks for all employees.
These test results were sent to each department and analyzed by group. Based on the results of this analysis, we prepared training for managers of workplaces with comparatively high stress levels in improving interpersonal relations within the workplace and improving the work environment.

Four Types of Care

This graphic shows our four types of care for mental health. They consist of self-care, line care, care by industrial health staff within business sites, and care by resources outside business sites.

Position-Based Mental Care Education

With an emphasis on self-care for new employees and young employees, we strive to deepen understanding of mental health by combining self-care and line care for new supervisors and key personnel.
We provide training for key personnel in areas with high occurrences of employee mental health problems with the goal of detecting and treating problems early on and putting these employees on the road to early recovery.

Promoting Better Health and Wellbeing Among Employees

In addition to annual health exams, NGK holds collaborative health promotion activities* with the health insurance association in efforts to promote better health and physical strength among employees. These activities include health lectures, health declaration challenges, the use of health apps for smartphones, physical strength measuring events, walking-age assessment events and related lectures, and recreational walks. New initiatives in FY2021 included streaming online fitness videos, holding online seminars on the themes of Dietary and Exercise Guidance and Exercising While Doing Daily Activities, and a quit smoking campaign.

An initiative in which health insurance associations work closely with companies and use their respective strengths to create a positive work environment by efficiently and effectively promoting the health and wellbeing of employees and their families.

Response to Infectious Diseases and Other Global Health Problems

There are approximately 450 NGK employees and family members posted overseas, and while the number of business trips by our employees in Japan decreased due to Covid-19, their number is steadily increasing. So we are cognizant of the possibility of their contracting infectious diseases. To reduce this risk, employees posted overseas and their families, as well as those taking business trips, are provided with health management training by specialists. Participants learn the fundamentals of infectious diseases, are advised to take immunization shots, and are taught ways to avoid contracting diseases like malaria.
During the influenza season from autumn to winter, employees posted overseas are encouraged to get vaccinated locally. We also offer vaccinations at the in-company clinic.
In addition, from June through March of FY2021, we provided workplace vaccinations for three rounds of Covid-19 vaccine injections to approximately 6,000 people. We also carried over our efforts from FY2020 in identifying close contacts of those infected with Covid-19, placed limits on office attendance, encouraged employees to eat without talking, and distributed free masks.
