A private-equity-owned national retailer referred a complaint alleging harassment by a senior executive against multiple subordinates. The investigation involved eight witness interviews across three states, forensic analysis of GPS and payroll data to verify travel schedules and expense claims, and review of electronic communications spanning 18 months. The challenge was structural: the private equity sponsor, the board, the executive leadership team, and the complaining employees each had different interests and different access to information. The investigation report included individualized credibility assessments for each witness (incorporating demeanor observations, internal consistency analysis, and corroboration mapping), organizational recommendations addressing both the specific complaint and systemic culture issues identified during the investigation, and a facilitated mediation plan for workplace relationships disrupted by the investigation process. The report was delivered directly to the board of directors.
