Does Just Culture also apply to suppliers, contractors and volunteers?

Yes, if they can see or influence risks they should be able to report safely and be treated fairly.

Do not limit Just Culture to employees with a permanent contract. Suppliers, contractors, researchers, interns and volunteers can be the first to see a vulnerability, error or unsafe situation. Give them an understandable reporting route, explain what protection applies and make it clear in agreements who will investigate and provide feedback.

The organization cannot unilaterally control all employment law or contractual consequences at another party. Therefore, agree in advance how information will be protected, when it will be shared and how retaliation or conflicts of interest will be prevented. In addition to employees, European aviation rules also refer to hired personnel; the EU whistleblowing rules may also include, within their scope, volunteers, self-employed persons and contractors.
