Managing Employment Investigations Best Practice for Compliance and Fairness

Handling internal investigations can be one of the most sensitive and high-risk aspects of managing people. Whether it’s a grievance, disciplinary issue, safeguarding concern or whistleblowing claim, how you approach the investigation process can make all the difference.

Done properly, investigations protect your business, demonstrate fairness, and reduce legal risk. Done poorly, they can lead to expensive tribunal claims, reputational damage, and a loss of trust across your team.

This webinar is designed to help SME leaders and HR professionals carry out robust, legally compliant investigations that follow best practice and align with the Acas Code of Practice.
