Expert Witness & Litigation Support

Evidence-based analysis of employee impairment, performance, and workplace safety disputes. Supporting employers, employees, and counsel nationwide.

Key Questions Courts and Juries Must Resolve

  • Evidence of Impairment

    • Do on-the-job behavior, performance issues, or supervisor observations support a conclusion of impairment?
    • Is the available evidence sufficient to justify disciplinary action?
    • Are conclusions based on impairment, rather than mere drug presence?
  • Drug Testing & Interpretation

    • Can an employer discipline an employee when a standard drug test is negative?
    • Does a positive drug screen equate to impaired job performance?
    • What are the scientific and legal limitations of workplace drug testing?
  • Performance, Safety & Causation

    • Was termination or discipline based on sound evidence of impairment?
    • Do certain drugs or medications preclude specific job functions or safety-sensitive duties?
    • Are off-duty drug test results relevant to on-duty performance or workplace incidents?

How 7 Arrow Supports Workplace Impairment Matters

When Impairment Evidence Drives Workplace Disputes, Expertise Matters

Drug impairment in the workplace cannot be evaluated through test results alone. Scientific credibility, real-world experience, and careful interpretation are essential when employee performance, safety, and legal liability are at issue.
