Internal reporting systems are crucial tools for compliance programs, but if companies do not ensure their employees know about and trust them, even the most technologically up-to-date system is of little use. Periodic trainings and reminders that boost the profile of the reporting system must augment a corporate culture that promotes ethical behavior and makes reporting a part of an ethical employee’s duties. In the second part of this two-part series, we explore how companies can encourage employees to use hotlines and how data collected from a hotline can be used to improve a compliance program. In the first part, we looked at the growing attention different jurisdictions are paying to whistleblower protection and internal reporting as well as how companies can ensure that their reporting mechanisms are up to date.
