Employment Expert Witness

We provide expert witness testimony in employment cases.

If you’re involved in an employment dispute, many elements of the case could require the services of an expert employment witness. At The Knowles Group, we’ve testified as a forensic economist in many employment-related cases and can help perform complex wage loss, pension loss and other economic damage assessments.

From sexual harassment to discrimination and hostile work environments, we can help you or your clients determine past and future income losses as well as complicated economic damages. Over the past 30 years, we’ve testified in federal and multiple state courts throughout the U.S.

Types of Employment Expert Witnesses

An employment expert witness is someone who is credentialed and licensed to provide an expert opinion in matters pertaining to employment law. From wrongful termination to workplace discrimination, these experts can help bolster the case of either plaintiff or defendant.

Some types of expert employment witnesses can include:

Forensic Economist Expert Witness

A forensic economist is responsible for determining income losses, economic damages, wage loss, wage loss valuation, and other damages associated with the case. They will accomplish this through a thorough records review as well as a comprehensive search of both public and private records such as:

  • Earnings History
  • W2 statements
  • Social Security Administration
  • State unemployment
  • Payroll records
  • Federal/State tax returns
  • HR Expert Witness

HR Expert Witness

An HR witness is an employment expert in matters that pertain to all aspects of Human Resources (HR). This can include hiring, firing, company policy, and state/federal laws. HR expert witnesses usually also have knowledge of complex regulations and labor laws, compliance, and employee assessment.

Americans with Disabilities Act (ADA) Expert Witness

The ADA prohibits discrimination against Americans with disabilities. It’s part of their civil rights and ensures that individuals who are disabled are treated fairly and given the same reasonable opportunities as non-disabled people. ADA expert witnesses have an innate knowledge of the complex ADA codes and requirements that businesses are required to abide by.

Mental Health Expert Witness

A mental health expert can provide testimony regarding the duress and mental stress that a plaintiff suffered while employed at a company. They take complex psychiatric diagnoses and explain them at a level that the average layman can understand. In some cases, a mental health expert may be currently treating the patient and can help shed light on what the patient is suffering from using a psychiatric perspective.

Vocational Rehabilitation Expert Witness

A vocational rehab expert can offer their expert opinion as to whether or not the worker can return to the same or similar line of work. They can also provide expert advice on whether or not the plaintiff has made a reasonable attempt at finding new employment.

Types of Employment Law Cases

There are many different kinds of employment law cases that can occur when an employer and employee are at odds with one another. Many of these cases can result in litigation or other employment disputes. Some of the more common types of employment law cases can include:

Wrongful Termination

While many states have what’s known as “at-will” employment, employers can still run afoul of the law if they terminate an employee for reasons that violate state or federal law such as discrimination or violations of the ADA act.

Hostile Work Environment

Hostile work environments can include offices, construction job sites, or anywhere an employee is expected to perform his or her job.

Sexual harassment is a common type of lawsuit that’s based on a hostile work environment. The worker alleges that he or she is being harassed sexually or expected to perform sexual favors in exchange for preferential treatment or promotions.


Workplace discrimination can be based upon one of many different things, such as:

  • Age
  • Sex
  • Religion
  • Disability
  • Sexual preference
  • National origin

Discrimination can happen anywhere in the workplace. Hiring, firing, promotions, pay, and job training are just a few of the areas where employees can face discrimination.


Retaliation cases can occur if a worker was laid off, fired, or otherwise had their hours or wages cut based upon them exercising a legal right (such as maternity leave), or because they stood up for themselves and opposed discriminatory treatment.

What is the EEOC?

The Equal Employment Opportunity Commission (EEOC) is a federal agency that’s designed to help protect the federal rights of workers in the U.S. The organization files lawsuits and pursues financial compensation for workers who have experienced discrimination, harassment, or wage-related issues stemming from the companies they work for.

The EEOC Helps Protect American Workers By:

  • Enforcing an equal pay standard for both men and women.
  • Defending workers under the Civil Rights Act of 1964. This includes discrimination against sex, race, religion, or national origin.
  • Defending women against pregnancy discrimination. It also helps ensure that employers do not discriminate against women who are suffering from medical or other ill effects due to pregnancy or childbirth.
  • Enforcing the Age Discrimination in Employment Act of 1967, which helps protect workers 40 years and older.

Wage and Benefit Loss Calculation Expert

Forensic economists are often called upon to testify about wage and benefits loss as well as other pertinent economic damages. In more complex cases, they may be required to determine the amount of financial damage the employee sustained from a particular action such as wrongful termination.

If they are testifying in a worker’s compensation case, a forensic economist might need to determine how much money the injured worker has lost due to the work-related accident. They can also calculate and testify regarding the present value of lost future income as well.
