Human Rights and Labor

Print this page

Basic Philosophy

The NGK SPARK PLUG Group respects the Universal Declaration of Human Rights and other international norms, and has made respect for human rights a part of our corporate code of conduct and our human resource policy. In addition, the group rules that we share throughout the NGK SPARK PLUG Group forbid discrimination on the basis of nationality, race, ethnicity, religion, sex, marital status, pregnancy, ideology, sexual orientation (LGBT), disabilities, and participation in labor unions, as well as all forms of harassment, child labor, and forced labor. In hiring and employment, too, we stipulate the granting of equal opportunity without discrimination.
Principles concerning human rights and labor are incorporated in the ten principles of the United Nations Global Compact which we joined in November 2016.The Group supports these principles and will connect them to our further activities.

Education and Awareness-Raising of Human Rights

Our Compliance Guidebook, issued in 2012, establishes matters including respect for human rights and the prohibition of harassment. The guidebook has been disseminated to employees to raise awareness of these issues.
Drawing on the United Nations Global Compact, which we signed in 2016, we will increase opportunities to offer education and information on human rights to raise awareness among employees.
In our CSR Procurement Guidelines, we also require that business partners engage in respect for human rights.

Anti-harassment Measures

The company management and the labor union are working together to prevent any harassment and to protect the human rights of all employees.
Work Rules explicitly prohibit all sorts of behavior that constitute harassment, and we have an anti-harassment committee responsible for the prevention of such behavior by raising awareness through the company newsletter and provide level-specific training programs.
We have also prepared an environment that facilitates consultation, with consultation desks set up by labor and management in every factory, and have also enabled consultation through our Corporate Ethics Helpline.

Labor-management Relations

Labor-management relations should be oriented to the combined employer-employee effort to contribute to society through the provision of good products and services. At NGK SPARK PLUG CO., LTD., both labor and management understand their respective responsibilities and strive to improve the work environment through mutual trust and cooperation.
Labor-management conferences are held three to four times a year on individual workplace and companywide bases, providing communication opportunities. These are chances to discuss various topics including the company's situation and how to improve the labor environment, and opportunities for employees to have their opinions heard.

Reduction in Working Hours

We are working to reduce overtime in order to reduce total working hours. When pre-planned overtime is known about, the company management and the labor union confirm the situation in the workplace and engage in consultation designed to keep working hours within the target.
As a result of addressing the issues discussed in the “committee on labor-management working style”, we are promulgating no-overtime Wednesday and in-principle prohibition of late-night overtime in excess of five hours per day. The case failing to comply with the rules is expected to be subject of the labor-management consultation as a strategy for suppressing overtime work.

Greeting Campaign

We have been engaging in our "greeting campaign" continuously since September 2008, encouraging employees to greet with each other, motivating them for work in the positive environment.
Once a month, in the morning and after work, representatives of the labor union and the company’s officers and management stand on the sidewalks at the premises to greet arriving or leaving employees in an active manner.

Scene from the Greeting Campaign

Group Company Response to Compliance

Group companies as a whole have been addressing the issue of information sharing for company compliance with the latest applicable laws and regulations. In the quarterly exchange meeting where general managers of the group companies attend, the briefing is made with respect to the policy based on current trends in applicable laws and regulations. We have been working to develop the group-wide risk management system by sharing the problems raised by the individual group companies as those that they face, and presenting case examples. The entire group continues to join hands in compliance issue.
