Siemon Supplier Code of Conduct

Effective July 28, 2023

Siemon and its affiliates worldwide (“Siemon”) are committed to respecting labor and human rights in all its operations. We believe that all people are entitled to the same fundamental rights and freedoms, regardless of their race, religion, gender, nationality, or any other characteristic. We are committed to this policy and to working with others to promote human rights and environmental sustainability around the world. Specifically, we are committed to providing a safe and healthy work environment for all employees, and we believe that all workers have the right to be treated with dignity and respect. Siemon is committed to ethical business practices which means dealing honestly, respectfully, and being mindful of our obligations to our employees, customers, suppliers, and to the community and environment. Siemon fully embraces Environmental, Social and Governance (ESG) principles and is fully committed to the Responsible Business Alliance Code of Conduct (RBA), United Nations Global Compact (UNGC) and Science Based Targets initiative (SBTi). We strongly encourage our Suppliers to do the same.

We regard ESG as a total supply chain initiative that requires our Suppliers to acknowledge and implement policies and systems that have a meaningful positive impact on environmental and social wellbeing within their control and influence. We strive to work with Suppliers who share our values, lead by example, and continually improve.

Labor and Human Rights

We expect Suppliers to commit to working with others to promote human rights around the world. A Supplier’s policy when recruiting, hiring, training, promoting, and terminating employees shall not discriminate based on race, color, religion, sexual orientation, veteran status, pregnancy, age, national/regional origin, marital status, ancestry, gender, mental or physical disability, or any other characteristic as protected by federal or local law. Suppliers shall reasonably accommodate all applicants and employees so long as doing so does not create an undue hardship. We expect our Suppliers to adhere to the Responsible Business Alliance code of conduct (RBA) as well as the United Nations Global Compact (UNGC), and to share our commitment to upholding the human rights of all employees and treating them with dignity and respect in the following ways.

Freely Chosen Employment

Suppliers shall not use forced, bonded (including debt bondage) or indentured labor, involuntary or exploitative prison labor, slavery or human trafficking. This includes transporting, harboring, recruiting, transferring, or receiving persons by means of threat, force, coercion, abduction or fraud for labor or services. As part of the hiring process, all workers must be provided with a written employment agreement in their native language that contains a description of terms and conditions of employment. All work must be voluntary, and workers shall be free to leave work at any time or terminate their employment without penalty if reasonable notice is given. Suppliers can only hold documentation if such holdings are required by law. In this case, at no time should workers be denied access to their documents. Workers shall not be required to pay Supplier’s agents or sub-agents’ recruitment fees or other related fees for their employment. If any such fees are found to have been paid by workers, such fees shall be repaid to the worker.

Young Workers

Child labor shall not to be used. Suppliers must not employ anyone under the age of sixteen (16). Workers under the age of 18 must not perform work that is likely to jeopardize their health or safety, including night shifts and overtime.

Working Hours

Workers should not labor more than the maximum hours of daily work set by local and national laws and regulations. Any overtime work should be voluntary and paid in accordance with existing local and national laws and regulations. Workers should not work more than 60 hours in a single work week, including overtime, except in emergency or unusual situations. Every effort will be made to ensure workers have at least one day off per seven-day week.

Wages and Benefits

Suppliers must compensate their employees for all overtime worked at the legal payment rate and provide their employees with a pay stub or similar documentation. Wages and benefits paid for a standard working week must meet local and national legal standards, including those relating to minimum wages, overtime hours and legally mandated benefits.

Humane Treatment

Suppliers shall establish disciplinary policies and procedures in support of the humane treatment of workers and the requirements shall be clearly defined and communicated to workers. There shall be no harsh or inhumane treatment including violence of any sort, sexual harassment, sexual abuse, corporal punishment, mental or physical coercion, bullying, public shaming, verbal abuse or any other conditions that contribute to a hostile work environment; nor is there to be the threat of any such treatment. Disciplinary policies and procedures in support of these requirements shall be clearly defined and communicated to all employees.


Suppliers must abide by local laws and regulations regarding workers’ contracts. Workers shall be granted any annual leave, sick leave and maternity/paternity leave as legally required without any negative repercussions and shall maintain employee records as required by local and national laws and regulations. Suppliers shall maintain and utilize employment policies and practices that do not discriminate based on race, religion, sexual orientation, veteran status, pregnancy, age, national/regional origin, marital status, ancestry, gender or mental or physical disability or any other characteristic as protected by all applicable laws and regulations. Workers shall be provided with reasonable accommodation for religious practices. In addition, workers or potential workers should not be subjected to medical tests or physical exams that could be used in a discriminatory way.

Freedom of Association

In conformance with local law, Suppliers shall respect the right of all workers to form and join trade unions of their own choosing, to bargain collectively, and to engage in peaceful assembly as well as respect the right of workers to refrain from such activities. Workers and/or their representatives shall be able to openly communicate and share ideas and concerns with management regarding working conditions and management practices without fear of discrimination, reprisal, intimidation, or harassment.
