Returning to work after maternity leave in the US: what you get

Three separate federal laws, and none of them is about flexibility

Returning to work in the United States is governed by a patchwork rather than a single entitlement. The FMLA protects your job. The FLSA, as amended by the PUMP Act, protects your ability to express milk. The PWFA requires accommodations for limitations arising from childbirth. None of the three gives you a right to work reduced or flexible hours. That has to be asked for, and this page is about asking well.

Job restoration under the FMLA

The FMLA entitles eligible employees of covered employers to unpaid, job-protected leave and requires the continuation of group health benefits on the same terms as if leave had not been taken. The protection is restoration to the same or an equivalent job, not necessarily the identical desk and reporting line.

Equivalent is a meaningful standard: equivalent pay, benefits and other terms and conditions of employment. A return that comes with a pay cut, a demotion, the removal of a bonus scheme, or a shift to a materially worse schedule is not equivalent, and that is the point at which to seek advice.

Remember the eligibility tests are checked at the point leave begins: 12 months of service, 1,250 hours in the previous 12 months, and a worksite with at least 50 employees within 75 miles. If you did not qualify for FMLA leave in the first place, this restoration right is not what is protecting you.

Intermittent leave and a phased return

FMLA leave can be taken intermittently or on a reduced schedule when medically necessary for a serious health condition. For bonding with a newborn, intermittent or reduced-schedule leave is available only if the employer agrees. So a two-day-a-week return using remaining FMLA entitlement is possible, but it is a negotiation and not an entitlement.

Pumping at work: the PUMP Act

The Department of Labor's position is direct. The Fair Labor Standards Act requires employers to provide reasonable break time for an employee to express breast milk for her nursing child for one year after the child's birth, each time such employee has need to express the milk. Employees are entitled to a place to pump at work, other than a bathroom, that is shielded from view and free from intrusion from coworkers and the public.

Note what that gives you. Break time as often as you need it, for a full year, and a private space that is explicitly not a bathroom. It does not have to be a permanent dedicated room, but it has to be available when you need it and it has to be genuinely private.

The break time itself does not have to be paid, unless the employer already pays for breaks of that length or the employee is not completely relieved of duty. If you are answering email while pumping, that is working time.

Small employers can raise an undue hardship defence in limited circumstances, and some employees, notably certain transportation workers, have had different rules apply. If your employer tells you the law does not apply to them, ask them to say so in writing and check it against the Department of Labor's guidance rather than accepting it.

The PWFA reaches further down

The Pregnant Workers Fairness Act applies to employers with 15 or more employees, which is a far lower threshold than the FMLA's 50. It requires reasonable accommodation for known limitations related to, affected by, or arising out of pregnancy, childbirth or related medical conditions, unless that causes undue hardship.

The EEOC lists examples that matter on return: a changed work schedule, such as shorter hours, part-time work or a later start time; telework; temporary reassignment; additional, longer or more flexible breaks; and leave to recover from childbirth or related conditions. Lactation is expressly named as a related medical condition, and the EEOC states that where an employee is lactating and needs modifications to pump at work or nurse during work hours, it is not reasonable for the employer to demand documentation from a health care provider.

You do not need special words to trigger it. Telling your employer that you have a limitation arising from childbirth and need a change at work starts the interactive process, which is simply the two sides communicating about the limitation and the adjustment needed.

State law again does the heavy lifting

The Department of Labor advises checking with your state labor department for additional or greater protections, and more than 30 states and cities have laws requiring accommodations for pregnant workers. Several states go further than federal law on lactation breaks, requiring paid time or specifying room standards, and some give a right to request flexible or predictable scheduling. Those laws differ too much to summarise responsibly here, so look up your own state by name.

What to do, and in what order

Confirm your return date and job title in writing with HR before you come back, and ask them to confirm pay and benefits are unchanged. Write to them separately about pumping: say you will need break time and a private non-bathroom space, and ask them to identify the space before your first day. If you want reduced or flexible hours, frame it as a PWFA accommodation request if it relates to recovery or lactation, and as an ordinary business request otherwise. Keep every exchange in writing. And check your own state's lactation and accommodation laws, because they are frequently more generous than the federal floor.
