How Pennsylvania Employers Should Conduct Internal Workplace Investigations 

Why Workplace Investigations Matter for Employers

When allegations of misconduct arise in the workplace—such as harassment, discrimination, retaliation, or policy violations—employers must respond promptly and carefully. Conducting an internal workplace investigation allows employers to gather facts, address concerns, and reduce the risk of legal exposure.

In Pennsylvania, poorly handled investigations can lead to employment litigation, agency complaints, and reputational damage. A structured investigation process helps organizations resolve issues fairly while protecting both employees and the business.

When Employers Should Conduct a Workplace Investigation

Not every workplace dispute requires a formal investigation, but certain situations should always trigger a review.

Common circumstances include:

  • allegations of discrimination or harassment
  • retaliation complaints
  • workplace safety concerns
  • policy violations
  • employee misconduct or ethical concerns

Even informal complaints should be evaluated carefully to determine whether further inquiry is necessary.

Key Steps in a Workplace Investigation

Review the Allegations

Before beginning interviews, employers should review the complaint carefully. Identify the specific allegations, individuals involved, and potential policy violations.

Identify the Investigator

Investigations should be conducted by an individual who can remain impartial. This may include:

  • human resources personnel
  • compliance officers
  • outside investigators
  • legal counsel

Maintaining neutrality is essential to ensuring credibility.

Preserve Evidence

Employers should secure relevant documents before conducting interviews. Evidence may include:

  • emails and internal communications
  • personnel records
  • policy documents
  • security footage
  • digital records

Preserving evidence early prevents the loss of important information.

Conduct Interviews

Investigators typically interview the complainant, the accused individual, and any witnesses.

Interviews should focus on:

  • gathering factual information
  • clarifying timelines
  • identifying additional evidence

Maintaining confidentiality helps encourage honest participation.

Evaluate the Findings

After reviewing evidence and interview notes, investigators determine whether the allegations are supported by the facts.

Findings should be documented clearly and objectively.

Take Appropriate Action

If misconduct occurred, the employer must determine appropriate corrective action. This may include disciplinary measures, policy updates, or additional training.

Consistency in enforcement is critical to maintaining credibility and reducing legal risk.

Common Mistakes Employers Should Avoid

Delaying the Investigation

Waiting too long to investigate complaints may worsen workplace conflict and increase legal exposure.

Failing to Document the Process

Investigations should include detailed records of interviews, evidence reviewed, and findings.

Allowing Bias to Influence the Investigation

Investigators must remain objective and avoid assumptions about the outcome.

Ignoring Retaliation Risks

Employers should monitor the workplace after an investigation to ensure that employees are not subject to retaliation.

How Legal Counsel Supports Workplace Investigations

Legal counsel can help employers conduct investigations that are fair, thorough, and compliant with employment laws.

Attorneys may assist with:

  • evaluating allegations
  • structuring the investigation process
  • reviewing interview questions
  • analyzing evidence
  • advising on disciplinary decisions

Early legal guidance can help organizations avoid procedural mistakes that could complicate future litigation.
