Workplace whistleblowing occurs when an individual reports wrongdoing in an organisation, such as financial misconduct or discrimination. This person is often an employee but can also be a third-party such as a supplier or customer.

Internal whistleblowing is when someone makes a report within an organisation. Often companies implement whistleblowing channels for this purpose so that employees and other stakeholders can speak up if they become aware of misconduct. Employees can also report to their line manager.

Occupational whistleblowing is different to raising a workplace grievance. A grievance is a matter of personal interest and does not impact on the wider public, whereas whistleblower revelations relate to more serious and widespread concerns as outlined above.
