Complaint Investigations
Independent, confidential, and thorough fact-finding for public agencies and nonprofits.
When complaints arise, public sector organizations need an investigation process that is impartial, well-documented, and defensible. CPS HR provides independent workplace complaint investigations that help agencies address allegations of misconduct, protect employees, and meet obligations under internal policy and applicable laws.
We maintain strict confidentiality and deliver clear, factual findings to support informed decision making.
Why Use an External Investigator
Agencies often engage CPS HR when:
- Neutrality or independence is critical
- Complaints involve senior leadership or sensitive allegations
- Internal capacity or expertise is limited
- Additional credibility and risk mitigation are needed
As an independent investigator, CPS HR brings objectivity and public-sector expertise to help organizations move forward with confidence.
Our Workplace Investigation Approach
Our investigators follow a structured, policy-aligned process designed for fairness, clarity, and credibility in public sector environments:
- Plan – Clarify the scope of the investigation and review relevant policies, collective bargaining agreements, and applicable laws.
- Collect – Gather and review documents, digital records, and other evidence.
- Interview – Conduct impartial, well-documented interviews with complainants, respondents, and witnesses.
- Analyze – Evaluate credibility, corroborate facts, and synthesize findings against policy standards.
- Report – Deliver a clear, defensible report with factual findings and, when requested, recommendations.
CPS HR conducts investigations involving a wide range of workplace complaints, including:
- Harassment and sexual misconduct
- Discrimination (race, age, disability, and other protected classes)
- Retaliation and whistleblower claims
- Workplace violence, bullying, and hostile work environment concerns
- Fraud, embezzlement, and other policy violations
- Security breaches and other workplace conduct issues
Investigations may involve represented or unrepresented employees, sworn and non-sworn staff, and all organizational levels, including executive leadership.
