Employee Engagement
Once every two years NGK carries out a survey in order to visualize workplace vitality.
For the survey carried out in fiscal 2020, a total of 4,788 people took part (men: 4,207; women: 581). When compared against the average for other companies, the responses from NGK employees regarding job satisfaction and sense of relative importance tended to be higher. Also, job satisfaction scores were higher than those from the previous survey conducted in fiscal 2018.
These survey results will be utilized as basic data for use in developing human resource measures focused on creating an organization that is more work-friendly and offers employees a sense of challenge. The workplace-specific results will also be provided as feedback to supervisors and used for workshops intended to enhance division vitality, thereby contributing to improvement in the daily workplace environment.
In the future, divisions needing to improve their scores will be visited individually and provided with organizational development support.
