It’s The Law
Federal legislation requires mandatory training on workplace harassment and violence be provided to all employees, including the employer and designated recipients of complaints.

Some provinces also have provisions recognizing that family violence can extend to the workplace. Employers in these provinces are required to take all reasonable precautions to protect workers from potential impacts in the workplace.

What is a workplace investigation?
A workplace investigation is a structured process used to examine allegations of misconduct, harassment, bullying, or other inappropriate behavior in the workplace. The goal is to gather facts, interview relevant parties, and evaluate evidence in a fair, impartial way. A professional workplace investigator ensures that the process remains unbiased, trauma-informed, and confidential. The outcome is a well-documented report with clear findings, helping organizations make informed decisions while maintaining trust and minimizing legal or reputational risks.
Why is impartiality important in workplace investigations?
Impartiality ensures that all parties involved in an investigation are treated fairly and without bias. When investigations are handled internally by managers or HR staff, there can sometimes be real or perceived conflicts of interest. By hiring an independent investigator, organizations demonstrate neutrality, protect employee trust, and reduce the risk of challenges to the findings. Impartial investigations also hold up better in legal or regulatory reviews, which is crucial for minimizing liability and ensuring compliance with workplace laws.
