8. Discrimination (Employment and Occupation) Convention, 1958 (No. 111)

In accordance with the ILO fundamental conventions, and as set forth more fully below, Suppliers shall commit to uphold human rights of workers and treat workers with dignity and respect. This commitment applies to all workers including temporary, migrant, student, contract, direct employees or any other worker.

Corning is aware the use of recruitment and labor agencies increases the risk of forced labor.

All labor agents acting on behalf of Corning and its suppliers must have a clear policy that adheres to this Code. Labor agents acting on behalf of Corning must conduct due diligence with employment and recruitment agencies and sub-agents in relevant countries of operation to ensure compliance to Corning’s Supplier Code of Conduct.

1. Freely Chosen Employment

Suppliers shall not use forced, bonded or indentured labor or involuntary prison labor. All work will be voluntary, and workers should be free to leave work or terminate employment upon reasonable notice. Prohibited actions include transporting, harboring, recruiting, transferring or receiving persons by means of threat, force, coercion, abduction or fraud for labor or services. In the hiring process, Suppliers should provide workers with a written employment agreement in their native language that contains a description of terms and conditions of employment. No changes or substitutions to this agreement should be allowed unless these changes are to meet local law or provide equal/better terms. 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. Employers and agents may not hold or otherwise destroy, conceal, confiscate or deny access by employees to their identity or immigration documents, such as government-issued identification, passports or work permits, unless such holdings are required by law.  Workers should not be required to pay employers’ or agents’ recruitment fees or other related fees for employment. If such fees are found then these fees should be repaid to the worker.

Corning employees can be offered common courtesies normally associated with accepted business practices, so long as these are offered openly and not in a form that could be construed as a bribe, payoff or secret compensation. Except where another Corning policy may provide for stricter limits, individual gifts from Suppliers may not exceed $100.00 USD per gift in value, and the total value of all gifts in a calendar year that may be accepted from a single Supplier may not exceed $100.00 USD. Regardless of value, items deemed not acceptable include gifts or raffles or tickets to sporting events, discounts on personal purchases, gift certificates, payment for travel, or other expensive gifts. Business lunches or dinners are acceptable if not excessive and if Corning and the Supplier take turns paying for such events.
