Fair Treatment and Evaluation

Human Resource System for Group S/M/J Employees

NGK’s human resource system for Group S/M/J employees is one which enables all employees, from the young to the experienced, to work with enjoyment and fulfillment. As NGK develops its businesses globally and promotes the creation of new products and businesses, it is essential to motivate young and middle-level employees who will take on future key roles and encourage them to demonstrate their full potential. We are aiming to create an environment that makes these possible.

Key Points of the Revised System

Qualification Definitions

In order to ensure that educational background and age are not limiting factors for employees’ careers, NGK maintains a merit-based qualification system for job promotion and grade transfer. Qualification-specific role differences are made clear, so employees are aware of what is required for higher level qualifications and can more readily attempt higher level job duties. The aim of this system is to reward the efforts of those with the will and ambition to move to a higher grade, as well as to facilitate each employee’s journey along his or her career path.

Evaluation System

NGK uses the following evaluation systems when determining individual compensation to maintain fairness in treatment, to thoroughly evaluate each individual’s efforts and achievements each time, and to allow employees to feel their own growth.

Evaluation System Content Ratio of Applicable Employees
Performance evaluations We evaluate the level of achievement and process of targets set at the beginning of the term as results. We evaluate to what extent employees have tackled work other than the targets they have been set. 100%
Role evaluations
(group S/M/J employees only)
We evaluate to what extent employees have fulfilled the roles expected of them (qualification definition) with the elements stipulated for each qualification. 100%
Evaluation interviews Employees have an interview with their supervisors about the setting of targets at the beginning of the term, improvement in the persuasiveness of the evaluation results with feedback at the end of the term, results in the applicable fiscal year, issues for the following fiscal year, and medium- to long-term career plans. 100%

Fair and Equitable Compensation

NGK and the Labor Union have signed an agreement that sets out original in-house minimum wages, which are fixed at a rate above the minimum wages by region and industry stipulated by the Minimum Wage Act. Through this agreement, we strive to improve employees’ working conditions and avoid violation of relevant laws.
We also apply a system that provides the same wages for the same qualifications, irrespective of sex.

Communication with Employees

Employee Engagement

Every year, NGK carries out an engagement survey. (Conducted biannually until FY2022)
For the survey carried out in FY2023, a total of 5,036 people took part (men: 4,410; women: 626). 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.
These survey results will be utilized as basic data for use in developing human resource measures focused on creating an organization that is more worker-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 vitality, thereby contributing to improvement in the daily workplace environment.

Protecting the Right to Collective Bargaining

NGK and the Labor Union have signed a labor agreement as equal partners. The agreement specifies that both parties shall respect each other’s rights and take responsibility for the exercising of their own rights. The two sides regularly hold Labor-Management Advisory Board meetings to exchange information and promote mutual understanding. They also maintain healthy labor-management relations by exchanging opinions on issues such as management policies, financial conditions, and activities of the Labor Union.
Collective bargaining sessions are held in an orderly manner, with both parties striving in good faith to resolve issues peacefully and promptly.

Communication Between Labor and Management

NGK makes an effort to build labor-management relations founded on mutual trust through communication with various consultative bodies, such as the Labor-Management Advisory Board, the Worksite Advisory Board, and the Regular Labor-Management Council.
NGK and the Labor Union hold Labor-Management Advisory Board meetings to talk about business conditions and performance, and Worksite Advisory Board meetings to share issues pertaining to manufacturing, work systems, and workplace environments from each worksite. In addition, labor and management also proactively exchange opinions at Regular Labor-Management Council meetings.

Notification of Transfers due to Business Necessity

NGK stipulates in the labor agreement we have entered into with the NGK Labor Union to determine any transfers due to business necessity upon considering the abilities, health and family circumstances of the employees in question. In addition, we have adopted rules to inform the individuals to be transferred at least three weeks in advance in principle.
In particular, we have stipulated in the labor agreement that we will consult with the union in advance when collectively transferring employees or other matters judged to have a major impact on union activities.
