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

The Fair Labor Standards Act (FLSA), 29 U.S.C. § 207(r), requires employers to provide nursing mothers with reasonable break time to express breast milk and a private space for lactation that is not a bathroom. The law applies to employers covered by the FLSA, which includes most private employers with at least two employees working together on a regularly recurring basis. The frequency and duration of breaks are determined by what is 'reasonable' under the circumstances—typically 15 to 20 minutes per session, as often as the mother needs.

The FLSA does not require employers to pay for pumping breaks, though individual states or employers may choose to do so. Employers with fewer than 50 employees at a single worksite may claim undue hardship; however, this is a difficult standard to meet and requires proof that compliance would impose a substantial burden on the employer's business. The U.S. Department of Labor (DOL) enforces these protections through the Wage and Hour Division.

Retaliation against an employee for requesting break time or using the private space for lactation is prohibited. Nursing mothers who are denied these accommodations may file a complaint with the DOL or pursue a lawsuit for damages including back pay and liquidated damages.

Missouri Revised Statutes § 285.047 strengthens nursing mothers' protections beyond the federal baseline. The statute requires employers to 'make reasonable efforts' to accommodate nursing mothers by providing break time and a private space to express milk. This language is similar to federal law but is codified specifically in Missouri employment law, giving workers an additional avenue for enforcement at the state level.

Under Missouri law, the right to pump applies to all employees, regardless of whether the employer is covered by the FLSA. This is important for employees of very small businesses (fewer than two employees) or those in categories the FLSA might not technically cover. The private space requirement is the same as federal law: it must not be a bathroom and must be reasonably private.

Missouri does not define the length of breaks or the frequency in the statute, meaning courts and regulators apply the same 'reasonable' standard used federally—typically 15 to 20 minutes per session, as often as medically necessary. The statute does not require employers to pay for pumping breaks unless the break is considered work time under other state or federal wage laws.

Missouri employers have no explicit safe harbor against liability if they accommodate nursing mothers, meaning employers cannot be sued by other employees for providing these accommodations. The state has not created any broader definition of 'private space' than federal law; a curtained area in an office, a dedicated lactation room, or a temporary use of a private office all satisfy the requirement.

Remedies under Missouri law include filing a complaint with the Missouri Department of Labor and Industrial Relations, Division of Labor Standards, or pursuing a private civil action for damages, including compensatory damages for lost wages and emotional distress, and in some cases punitive damages if the violation is willful.

Employers with fewer than 50 employees may claim 'undue hardship' under the FLSA, but this requires proof that accommodation would impose a substantial burden on business operations. Undue hardship is not a simple exemption; it requires the employer to demonstrate that providing break time or space would significantly disrupt production, create substantial cost, or fundamentally alter the business model.

Bathroomspaces do not qualify as private space under either federal or Missouri law, even if the bathroom is clean and private by itself. Employers are not required to provide paid break time for pumping unless the break occurs during time the employee is otherwise compensated (such as if the pumping happens during an already-paid rest break).

Employees who refuse to use lactation accommodations or who stop nursing are not entitled to ongoing protections under the statute. However, an employer cannot condition employment, scheduling, or advancement on whether an employee uses pumping breaks.

The FLSA exception for 'independent contractors' applies in Missouri as well; true independent contractors are not covered by either the federal or state nursing mothers law. However, employers misclassifying employees as independent contractors to avoid providing accommodations face liability.

Union employees may have additional or alternative protections negotiated in their collective bargaining agreement; however, the agreement cannot take away rights granted by statute. At-will employment principles do not override the right to pump—an employer cannot fire an employee solely for using lactation break time, as this would violate public policy under Missouri law.

Step 1: Document Everything. Keep a detailed record of each time you requested break time or private space and what the employer said or did in response. Write down the date, time, what you asked for, who you spoke to, and what happened. Take screenshots of any emails or messages. Keep receipts for any additional expenses incurred (e.g., purchasing a personal pump or traveling to an offsite location to pump). Note any comments made by supervisors or coworkers about your pumping, breastfeeding, or your request for accommodations. This documentation is critical for proving the violation and damages.

Step 2: Make an Internal Complaint. Before filing outside, notify your employer in writing (email is acceptable) that you are requesting lactation break time and private space in accordance with Missouri law and federal law. Use clear language such as: 'I am requesting reasonable break time and a private, non-bathroom space to express breast milk as required by Missouri Revised Statutes § 285.047 and the Fair Labor Standards Act.' Request a written response. This creates a formal record and gives the employer a chance to comply. If the employer refuses, provides only a bathroom, or retaliates, document that response immediately.

Step 3: File a Complaint with the Missouri Department of Labor and Industrial Relations. Contact the Division of Labor Standards at the address or phone number listed below. You can file a complaint online or by mail. The complaint should include your name and contact information, your employer's name and address, a description of what happened, dates, witnesses, and copies of your documentation. There is no specific deadline to file, but do not delay—the statute of limitations for federal claims is generally two years (three if willful). The state agency will assign an investigator who will contact your employer and ask for their response.

Step 4: The Investigation Process. The Missouri Department of Labor will conduct an investigation, which typically takes 30 to 60 days, though it can take longer if the case is complex. The investigator will request documents from your employer, including your personnel file, schedule, policies, any written communications about pumping, and your employer's statement. You may be asked to provide additional information. The investigator does not make a final determination but will file a report. If the employer is found to have violated the law, the department may issue a citation and seek back wages or other remedies. You will be notified of the outcome.

Step 5: Consider Filing a Federal Complaint or Pursuing Private Legal Action. If the state investigation is unsatisfactory or slow, you can file a complaint with the U.S. Department of Labor Wage and Hour Division (federal FLSA claim). You can also consult an employment attorney who specializes in wage and hour or discrimination law. An attorney can help you assess whether to pursue a private lawsuit for damages, including unpaid wages, compensatory damages (for emotional distress, lost income, or cost of alternative pumping arrangements), and potentially punitive damages if the violation was willful. Many employment attorneys work on contingency, meaning they only collect a fee if you win or settle.
