More whistleblowers than ever before filed reports with their employers in 2022, with more than half doing so anonymously, according to the latest hotline benchmark report from NAVEX.

The “2023 Risk and Compliance Hotline and Incident Management Benchmark Report,” released Tuesday, analyzed whistleblowing trends among 52 million employees across 3,430 organizations that received 10 or more reports in 2022—a database of 1.52 million reports from across the globe.

The rise in total reports, which included the highest observed median level of reports per 100 employees (1.47), showed increasing numbers of employees knew about and used their companies’ internal reporting platforms.
