Page 3 “Whistleblowing - Celestica’s Audit Committee has adopted a Whistleblower Policy to provide for the receipt, retention, and treatment of complaints received by Celestica regarding accounting, internal accounting controls, or auditing matters, and confidential, anonymous submissions by employees of Celestica of concerns regarding questionable accounting or auditing matters.”
Also Page 3:
"Reporting Issues
Celestica has implemented an Ethics program to maintain a workplace of high ethical standards. The Ethics program is communicated to employees in the BCG policy, on the internet, intranet and through the Ethics Awareness Centers which are posted at each of Celestica’s sites providing all of the details around the ethics program, including the local hotline number in each geography. Celestica's Ethics program is available to anyone who has dealings with a Celestica employee whether that be an employee, customer, supplier or external stakeholder.In addition, Celestica is open to receiving any feedback or concerns about its management of modern slavery and human rights risks in its operations. Any concerns can be reported to compliance@celestica.com."
The Whistleblowing Policy on page 3 doesn't seem to be tailored for reporting human rights abuses:
"Celestica’s Audit Committee has adopted a Whistleblower Policyto provide for the receipt, retention, and treatment of complaints received by Celestica regarding accounting, internal accounting controls, or auditing matters, and confidential, anonymous submissions by employees of Celestica of concerns regarding questionable accounting or auditing matters."
The Ethics program is "available to anyone who has dealings with a Celestica employee whether that be an employee, customer, supplier or external stakeholder" which sounds like the complaint mechanism is aimed at protecting Celestica's employees. There is an email to reporting any concerns, which could be used to flag issues with supply chain workers, even though it doesn't seem to be actively shared with them.
I selected "Hotline, Email.." for both employees and supply chain workers, even though the implementation re supply chain workers seems to be weak.
