Nursing Mothers Rights at Work in Washington: Pumping & Lactation Laws

The federal Fair Labor Standards Act (FLSA), 29 U.S.C. § 207(r), requires employers with 50 or more employees to provide break time and a private space for nursing mothers to express breast milk. The federal requirement covers employers for one year after the child's birth and applies to non-exempt (hourly) employees. Break time is not required to be paid under federal law, though many states require paid breaks. The U.S. Department of Labor (DOL) enforces the FLSA nursing mother provisions through the Wage and Hour Division. Violations may result in back pay and wage claims. However, the FLSA exempts employers with fewer than 50 employees within 75 miles of the work site, and small employers are not required to comply with the federal standard.

Under the federal standard, employers must make reasonable efforts to provide a private space that is not a bathroom. The law requires that break time be provided as frequently as needed during the workday. Remedies under federal law are limited to wage claims for unpaid break time if the employer fails to provide it, enforced through DOL wage and hour complaints or private lawsuits.

Washington's nursing mother law, codified in Revised Code sections 49.86.010 through 49.86.030, is significantly stronger than federal law and applies to all employers in Washington, regardless of size. Washington's law has no employee count threshold, meaning it covers employers with even one employee, whereas federal law only covers employers with 50 or more employees.

Under Washington law, employers must provide reasonable paid break time for nursing mothers to express breast milk. The law specifies that this break time must be in addition to any existing break periods and does not reduce the employee's regular compensation. Washington requires employers to provide a private space other than a bathroom for expressing breast milk, and the space must have electrical outlets if the mother needs to use an electric pump. The law applies during the first year after the child's birth or longer if mutually agreed.

Washington law differs from federal law in several critical ways: first, break time must be paid in Washington, while federal law does not require paid breaks; second, Washington's law applies to all employers regardless of size; third, Washington law explicitly requires an electrical outlet and a non-bathroom private space. Additionally, Washington law provides stronger remedies than federal law. Under RCW 49.86.030, violations constitute unfair or deceptive acts under the state's Consumer Protection Act (RCW 19.86), meaning employers face civil penalties of up to $2,000 per violation, treble damages, and attorney fees. This is far more punitive than federal wage claims alone.

Washington's law also protects nursing mothers from retaliation or discipline for taking break time to pump, and employers cannot reduce compensation or benefits as a result of the employee taking nursing breaks. The law is intentionally broader than federal law to ensure all Washington workers, including those at small employers, have access to nursing accommodations.

Washington's nursing mother law applies broadly, but certain narrow exceptions exist. First, the law applies during the first year after childbirth or until nursing ends, whichever is earlier; however, the parties may mutually agree to extend this period. Second, the law does not apply if providing break time would cause undue hardship to the employer due to the nature of the business, though this exception is interpreted very narrowly and the employer bears the burden of proof.

The undue hardship exception requires the employer to demonstrate substantial and significant difficulty or expense in providing break time and a private space. This is a high bar—mere inconvenience is insufficient. Courts have interpreted this narrowly, and it is rarely successful in litigation. The employer must make a documented effort to accommodate the nursing mother before claiming undue hardship.

Another potential exception applies to employees who work in customer-facing roles or in highly specialized positions; however, Washington law still requires the employer to make reasonable efforts to accommodate even these employees. Employers cannot simply deny pumping rights because the employee works in a visible or specialized role.

The law does not apply to the extent that federal law preempts it, but since Washington's law is stronger than federal law, preemption rarely applies. Self-employed individuals and independent contractors are generally not covered, as the law applies to employer-employee relationships. Additionally, if an employee is pumping during unpaid breaks (outside of paid break times), the employer has less obligation to provide a private space, though most employers should do so to avoid liability.

Step 1 — Document Everything: Keep a detailed log of every time you requested break time to pump and whether it was granted or denied. Record the date, time requested, duration needed, whether you were allowed to take the break, and what the employer said. Save all written communications (emails, texts, messages) with your supervisor or HR about pumping accommodations. Photograph the space offered for pumping if it is a bathroom or otherwise unsuitable. Take photos of the lack of electrical outlets, lack of privacy, or poor conditions. Keep records of your job performance to show that taking pumping breaks did not affect your work.

Step 2 — Internal Complaint Process: Notify your supervisor or HR in writing (email is best to create a paper trail) that you need break time and a private space to pump. Be specific: "I need 15-20 minutes, twice daily, to express breast milk." Request a meeting to discuss reasonable accommodations. In the meeting, explain your needs clearly and ask for confirmation in writing of what the employer will provide. If the employer refuses or fails to respond, follow up in writing within 48 hours. Do not rely solely on verbal agreements. Keep copies of all written requests and responses. The internal complaint process is important because it puts the employer on notice and creates evidence of the violation if you later file a complaint.

Step 3 — File a Complaint with the Correct Agency: You have two options in Washington. Option A: File a complaint with the Washington Department of Labor & Industries (L&I), which enforces wage and hour laws including RCW 49.86. File online at lni.wa.gov/workers-rights or call 1-800-4-US-WAGE (1-800-487-9243). You will need: your name, contact information, employer name and address, dates of violations, description of what happened, and names of witnesses if applicable. There is no filing fee. Option B: File a civil claim directly in court under the Washington Consumer Protection Act (RCW 19.86) alleging unfair or deceptive practices, which allows you to seek treble damages and attorney fees. Many employees do this through a private attorney.

Step 4 — Investigation Process and Timeline: If you file with L&I, the agency will assign an investigator to your case. The investigator will contact you for more details, review documents you provide, and then contact the employer for their version of events. The investigation typically takes 30-90 days, though complex cases may take longer. The investigator will ask the employer to produce records of break time policies, any accommodations offered, and communications with you. L&I has the authority to conduct interviews and inspect the workplace to verify the private space exists. Once the investigation is complete, L&I will issue a determination of whether a violation occurred and, if so, order the employer to pay back wages (the cost of break time denied) and correct the violation going forward. If you file a civil claim in court instead, discovery will be more extensive and the timeline longer, typically 6-18 months to resolution.

Step 5 — Consult an Attorney: Contact a Washington employment attorney if: (1) the employer retaliates against you for filing a complaint or requesting pumping breaks, (2) L&I's investigation does not resolve the issue satisfactorily, or (3) you want to pursue maximum damages (treble damages and attorney fees under the Consumer Protection Act). Many Washington employment attorneys work on contingency (no upfront cost) and take pumping rights cases because the damages and penalties can be significant. A lawyer can also send a demand letter to the employer before filing a formal complaint, which often prompts faster resolution.
