Our Commitment

We work in an energetic global industry where the pace is fast and change is constant. But, there are some things that don’t change at Ribbon Communications (also, “Ribbon”) - our commitment to doing business honestly, ethically, and with respect for others. It is to this end that Ribbon Communications has implemented this Supplier Code of Conduct (“Code”) which mirrors many of the principles set forth in Ribbon Communication’s Code of Conduct.

It has always been paramount to our way of doing business at Ribbon Communications to comply with applicable law and to act with the utmost integrity, honesty, and transparency. Ribbon Communications is committed to acting responsibly in all our business dealings to ensure that we comply with applicable national and international legislation, including laws regarding anti-corruption, anti-trust, anti-bribery and fair competition, and human rights. Ribbon Communications will forgo business opportunities rather than act in an unethical manner and/or in violation of applicable law. Preserving an ethical workplace is critical to our long-term success as a company.

At Ribbon Communications, the message for each Ribbon Communications’ Supplier is clear: any success that is not achieved lawfully and ethically is no success at all. At Ribbon Communications, we obey applicable law and strive to hold ourselves to the highest ethical standards, and we expect the same of all our Suppliers. 

Human Rights and Labor

Ribbon’s Suppliers must commit to respect the human rights of workers, and to treat them with dignity and respect. This applies to Ribbon’s direct and indirect Suppliers, as well as all workers including temporary, migrant, student, contract, direct employe, and any other type of worker. In light of these commitments, Ribbon Communications’ Suppliers will:

Support Freely Chosen Employment: Forced labor in any form, including but not limited to, bonded (including debt bondage) or indentured labor, involuntary or exploitative prison labor, slavery or trafficking of persons is not permitted. This includes transporting, harboring, recruiting, transferring, or receiving persons by means of threat, force, coercion, abduction, or fraud for labor or services. There shall be no unreasonable restrictions on workers’ freedom of movement in the facility in addition to unreasonable restrictions on entering or exiting company-provided facilities including, if applicable, workers’ dormitories or living quarters. As part of the hiring process, all workers must be provided with a written employment agreement in their native language, or in a language which the worker can understand, that contains a description of terms and conditions of employment. Foreign migrant workers must receive the employment agreement prior to the worker departing from his or her country of origin and there shall be no substitution or change(s) allowed in the employment agreement upon arrival in the receiving country unless these changes are made to meet local law and provide equal or better terms. All work shall be voluntary, and workers shall be free to leave work at any time or terminate their employment without penalty if reasonable notice is given, which shall be clearly stated in workers’ contracts. Supplier shall maintain documentation on all leaving workers. Employers, agents, and sub-agents may not hold or otherwise destroy, conceal, or confiscate identity or immigration documents, such as government-issued identification, passports, or work permits. Notwithstanding the foregoing, employers can only hold documentation if necessary to comply with the local law. In this case, at no time shall workers be denied access to their documents. Workers shall not be required to pay employers’, 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. See Ribbon's Anti-Slavery and Human Trafficking Statement.

Comply with Young Workers Regulations: Child labor shall not be used in any stage of manufacturing. The term “child” refers to any person under the age of 15, or under the age for completing compulsory education, or under the minimum age for employment in the country, whichever is greatest. Workers under the age of 18 (Young Workers) shall not perform work that is likely to jeopardize their health or safety, including night shifts and overtime. Supplier shall ensure proper management of student workers through proper maintenance of student records, rigorous due diligence of educational partners, and protection of students’ rights in accordance with applicable laws and regulations. Supplier shall implement an appropriate mechanism to verify the age of workers. The use of legitimate workplace learning programs, which comply with all laws and regulations, is supported. Supplier shall provide appropriate support and training to all student workers. In the absence of local law, the wage rate for student workers, interns and apprentices shall be at least the same wage rate as other entry-level workers performing equal or similar tasks. If child labor is identified, assistance/remediation shall be provided.

Maintain Appropriate Working Hours:  Working hours shall not exceed the maximum set by local law. Further, a workweek shall not be more than 60 hours per week, including overtime, except in emergency or unusual situations. All overtime shall be voluntary. Supplier shall ensure that workers take at least one day off every seven days.

Provide Appropriate Wages and Benefits: Compensation paid to workers shall comply with all applicable wage laws, including those relating to minimum wages, overtime hours and legally mandated benefits. All workers shall receive equal pay for equal work and qualifications. Workers shall be compensated for overtime at pay rates greater than regular hourly rates. Deductions from wages as a disciplinary measure shall not be permitted. For each pay period, workers shall be provided with a timely and understandable wage statement that includes sufficient information to verify accurate compensation for work performed. All use of temporary, dispatch and outsourced labor shall be within the limits of the local law.

Implement Non-Discrimination, Non-Harassment, and Humane Treatment Policies and Processes: Supplier shall commit to a workplace free of harassment and unlawful discrimination. There shall be no harsh or inhumane treatment including violence, gender-based violence, sexual harassment, sexual abuse, corporal punishment, mental or physical coercion, bullying, public shaming, or verbal abuse of workers; nor is there to be the threat of any such treatment. Supplier shall not engage in discrimination or harassment based on race, color, age, gender, sexual orientation, gender identity or expression, ethnicity or national origin, disability, pregnancy, religion, political affiliation, union membership, covered veteran status, protected genetic information, or marital status in hiring and employment practices such as wages, promotions, rewards, and access to training. Disciplinary policies and procedures in support of these requirements shall be clearly defined and communicated to workers. Workers shall be provided with reasonable accommodation for religious practices and disability. In addition, workers or potential workers should not be subjected to medical tests, including pregnancy or virginity tests, or physical exams that could be used in a discriminatory way.

Allow Freedom of Association and Collective Bargaining:  Open communication and direct engagement between workers and management are the most effective ways to resolve workplace and compensation issues. 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. In alignment with these principles, supplier 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. Where the right of freedom of association and collective bargaining is restricted by applicable laws and regulations, workers shall be allowed to elect and join alternate lawful forms of worker representations.

Ribbon’s Suppliers must recognize that in addition to minimizing the incidence of work-related injuries and illnesses, a safe and healthy working environment enhances the quality of products and services, consistency of production and worker retention and morale.  Suppliers must also recognize that ongoing worker input and education are essential to identifying and solving health and safety issues in the workplace.
