Navigating the Pregnant Workers Fairness Act (PWFA) brings a wave of new responsibilities for human resources departments. You already know that the law requires you to provide reasonable accommodations for known limitations related to pregnancy, childbirth, or related medical conditions. You also know that you must engage in a timely, good-faith interactive process with your employees.
But what happens when an employee asks for something you simply cannot provide?
Under the PWFA, the only lawful way to deny a reasonable accommodation request is by proving that it would cause an "undue hardship" on your business. However, the legal definition of undue hardship is a very high bar to clear. Claiming a hardship just because an accommodation is annoying, slightly expensive, or disruptive to your preferred schedule is a fast track to an Equal Employment Opportunity Commission (EEOC) violation.
If you manage HR compliance, employee relations, or benefits administration, you must understand exactly how the federal government defines, measures, and audits this concept. This comprehensive guide breaks down the rigorous legal standard of undue hardship under the PWFA. We will contrast it with the Americans with Disabilities Act (ADA), explore the specific factors the EEOC considers, clarify the difference between temporary and permanent limitations, and show you how to properly document a denial to withstand legal scrutiny.
To understand when you can legally deny an accommodation, you first need to understand the standard you are being judged against. The PWFA borrows its baseline definition of undue hardship from the ADA, but it applies that definition to an entirely different set of circumstances.
The statutory definition of undue hardship is an action requiring "significant difficulty or expense." It means you cannot deny a request simply because it requires administrative effort or a minor financial cost. The accommodation must pose a serious threat to the financial viability or core operational structure of your organization.
For decades, HR professionals relied on the ADA framework to handle medical accommodation requests. Under the ADA, an accommodation is often meant to be a permanent, long-term adjustment for an individual with a recognized disability. Because the adjustment is permanent, the cumulative cost and operational drag over years or decades factor heavily into the undue hardship analysis.
The PWFA flips this framework. Pregnancy is not a disability, and the limitations associated with it are inherently temporary. Because the need for the accommodation will naturally expire—usually within a few months—the EEOC expects employers to absorb a much higher degree of short-term disruption than they might under the ADA. A schedule change that might cause a significant difficulty if implemented permanently for five years might only be viewed as a minor inconvenience if it only lasts for four months.
The phrase "significant difficulty or expense" is intentionally broad, allowing the EEOC to evaluate each situation on a case-by-case basis. There is no magic dollar amount or specific percentage of your operating budget that automatically qualifies as a hardship.
Instead, the EEOC looks at the holistic picture of your organization. A $5,000 piece of lifting equipment might be a significant expense for a small family-owned business with ten employees, but it would not even register as a minor expense for a Fortune 500 manufacturing company. You must evaluate the request against the actual reality of your specific business.
When an employee files a complaint alleging that you unlawfully denied an accommodation, the EEOC does not just take your word that the request was too hard to fulfill. They look at a specific, statutory set of factors to determine if your claim of undue hardship is valid.
If you are considering denying a request, you must analyze the situation using these exact same factors.
The first factor is the actual, out-of-pocket cost of providing the accommodation. You must look at the net cost, which means you should subtract any available tax credits, deductions, or outside funding that could help pay for the adjustment.
For example, if an employee needs a specialized ergonomic chair that costs $800, you must determine if spending that $800 is a significant expense for your company. If you are simply adjusting a schedule or allowing extra break times, the direct financial cost is usually zero, meaning you cannot use financial expense as your defense.
The EEOC looks at the specific facility where the employee works. They examine the number of employees at that location and the effect the accommodation would have on the expenses and resources of that specific site.
If the accommodation requires hiring a temporary worker to cover certain duties, and the budget for that specific retail location cannot cover an additional salary without going into the red, that facility might face an undue hardship.
However, looking at the facility is not enough. The EEOC also looks at the overall financial resources of the parent company or the "covered entity."
If a local branch of a massive national retail chain claims they cannot afford a $200 stool for a pregnant cashier, the EEOC will look at the national corporation's billions of dollars in revenue and immediately reject the undue hardship claim. You cannot hide behind a strict local department budget if the broader company has vast resources.
The final and often most contested factor is the impact of the accommodation on the operation of the facility. This means looking at how the accommodation affects the ability of other employees to do their jobs, and whether it fundamentally alters the nature of the business.
If an accommodation severely disrupts the workflow to the point that the business cannot function, that is an operational hardship. For example, if a pregnant warehouse worker requests to never lift more than five pounds, but the entire function of that specific small warehouse involves team-lifting 100-pound crates constantly throughout the day, accommodating that request might force the entire operation to halt.
One of the most complex concepts for HR teams to grasp under the PWFA is the timeline of the hardship. Because pregnancy is a temporary state, the EEOC evaluates undue hardship through a temporary lens.
When you evaluate a request, you must ask yourself: "Can we survive this disruption for the next few months?"
If an employee asks to work a reduced schedule for her third trimester to manage severe fatigue, you cannot deny the request by arguing that a permanent part-time schedule would ruin your department's annual output. You must analyze the impact of a 12-week schedule reduction. In most cases, businesses can absorb short-term productivity dips, meaning the undue hardship defense will fail.
The PWFA includes a revolutionary provision that sets it apart from almost all other employment laws. Under the ADA, if an employee cannot perform the essential functions of their job, you generally do not have to keep them in that role. Under the PWFA, you may be required to temporarily suspend an essential job function.
The law states that an employee is still considered qualified even if they cannot perform an essential function, provided that the inability is temporary, the function can be performed "in the near future," and the inability can be reasonably accommodated.
The EEOC defines "in the near future" for a current pregnancy as generally up to 40 weeks. This means you must consider whether you can remove a core job duty from an employee for up to nine months. If you want to deny this, you must prove that suspending that specific function for 40 weeks would cause an undue hardship. This is an incredibly high risk area for employers, making specialized EEOC Training a vital investment for your HR team.
The most frequent cause of PWFA compliance failures is a frontline manager confusing a personal inconvenience with a legal undue hardship. Your leadership team must understand the difference, and they must understand it before an employee makes a request.
An inconvenience is anything that requires administrative effort, frustrates a manager, or requires a temporary change to the way you prefer to do things. You cannot legally deny an accommodation based on an inconvenience.
Examples include:
If your managers are denying these types of requests, your company is liable. Educating your management team through rigorous Supervisor Training ensures they know exactly what they must approve and when to escalate complex requests to HR.
A genuine undue hardship threatens the core function or financial stability of the business. While rare, these situations do happen.
Examples include:
When you engage in the interactive process to determine if an accommodation causes an undue hardship, you cannot view the situation in a vacuum. Adjusting an employee's schedule, duties, or pay has immediate ripple effects across your entire HR infrastructure.
Sometimes, an employer genuinely cannot find a way to keep an employee working without causing an undue hardship. In these rare cases, a leave of absence may be the only reasonable accommodation available.
When you use leave as an accommodation, you must coordinate it perfectly with the Family and Medical Leave Act (FMLA) and your internal short-term disability policies. You must track the leave correctly and ensure the employee's job is protected. Furthermore, the PWFA explicitly prohibits you from forcing an employee to take a leave of absence if another reasonable accommodation would allow them to keep working. Managing these concurrent leave laws is complex, and errors are costly. Comprehensive FMLA Training gives your team the framework to manage these overlaps flawlessly.
When an accommodation involves reducing an employee's hours from full-time to part-time, it immediately impacts their benefits. Do they lose their health insurance eligibility? How are their premiums collected if they take an unpaid leave of absence?
Pregnant workers rely heavily on pre-tax benefits like Flexible Spending Accounts and Health Savings Accounts to cover prenatal care, hospital deductibles, and new dependent expenses. If an accommodation changes their employment status, it can trigger qualified life events that affect these accounts.
Your benefits team must understand how PWFA accommodations interact with IRS regulations. Building internal expertise through the Cafeteria Plan Training & Certification Program and the HSA Training & Certification Program ensures that you do not accidentally create a tax compliance nightmare while trying to solve a civil rights issue.

If you make the decision to deny an accommodation based on undue hardship, you must assume that your decision will be audited by the EEOC. If it is not documented, it did not happen. You need a bulletproof paper trail that proves you acted in good faith, evaluated the request against statutory factors, and exhausted all other options.
Your documentation must tell a clear, objective story. A note that says "Request denied, too expensive" will guarantee a loss in court.
Your file should include:
The most critical part of your documentation is proving that you offered alternatives. If you determine that an employee's preferred accommodation causes an undue hardship, the interactive process does not end. You must offer another accommodation that is as effective as possible without causing a hardship.
If an employee asks to work from home, and you prove that causes an undue hardship, document that you pivoted and offered them a flexible start time, extra breaks, and a temporary transfer to a desk-based role in the office. If the employee rejects the reasonable alternative, you are highly protected against a retaliation or discrimination claim.
The PWFA has fundamentally changed the landscape of workplace compliance. Relying on outdated ADA mentalities or informal managerial discretion is no longer an option. The legal standard for undue hardship is strict, the requirement for good faith is absolute, and the penalties for getting it wrong are severe.
Your frontline supervisors are the first line of defense. They receive the vast majority of accommodation requests. If they do not know how to recognize a request, or if they deny a simple request out of annoyance, your company is liable.
Your HR staff is the second line of defense. They must manage the interactive process, coordinate with payroll and benefits, analyze the legal standard of undue hardship, and maintain flawless documentation.
You cannot rely on trial and error to build this expertise. Continuous, specialized education is the only way to safeguard your organization. By investing in HR Certifications and targeted topical training, you empower your team to navigate these complex scenarios with confidence and precision.
Understanding undue hardship under the PWFA requires a shift in how employers view workplace accommodations. You must move away from the rigid, permanent frameworks of the ADA and embrace the temporary, flexible, and highly supportive intent of the PWFA.
Remember that inconvenience is never an excuse to deny a pregnant worker the support they need to safely do their job. Save the undue hardship defense for situations that genuinely threaten the financial and operational stability of your organization. By engaging earnestly in the interactive process, offering creative alternatives, and maintaining rigorous documentation, you protect your business while fostering a culture that truly supports its workforce.
