Montana: Lactation Break and Space Requirements

Ordinary private employment uses the federal floor

Montana's express workplace-lactation provisions, §§ 39-2-215 through
39-2-217, name state and county governments, municipalities, school districts,
and the university system. They do not create a general rule for an ordinary
private employer.

For covered private employment, federal § 218d(a) supplies reasonable break
time each time needed for one year after birth and a place other than a
bathroom that is shielded from view and intrusion. Section 218d(b) allows
unpaid time unless another law requires pay, but treats the entire period as
hours worked when the employee is not completely relieved from duty. Federal
§ 218d(g) also contains a separate pre-suit notice rule for certain
pumping-space claims.

The Montana public-employer rules are narrower in coverage but add several
details. Section 39-2-217 requires reasonable unpaid break time each day when
breaks are already allowed. If they are not, the employer must consider the
individual case and accommodate as possible. The time should run concurrently
with an existing break if possible, and the employer need not provide it when
doing so would unduly disrupt operations. The statute states no fixed
post-birth cutoff.

Sections 39-2-215 and 39-2-216 require a written support policy and reasonable
efforts toward a room or other location close to the work area, other than a
toilet stall. The policy must address privacy, lighting, and electricity. The
space may be temporary or not fully enclosed, but must be readily available
during the period the employee needs it. The statute does not require a chair,
surface, water, refrigeration, cleanliness standard, or lactation-use priority;
facilities for milk storage are encouraged rather than mandatory.

Section 39-2-215 also bars a public employer from refusing to hire, barring,
discharging, or discriminating in compensation or other employment terms
because an employee expresses milk, subject to its bona fide occupational
qualification clause. Sections 39-2-215 through 39-2-217 do not state a
lactation-specific administrative complaint route, private action, penalty,
damages measure, fee award, or cure rule.

What trips people up

The state break duty depends on the public employer's existing break
practice. If breaks are already allowed, reasonable unpaid time each day is
required. If not, the statute uses case-by-case consideration and
accommodation-as-possible language, plus the undue-disruption limit.

The space may be temporary, but availability is mandatory. A public
employer need not dedicate a permanently enclosed room. Its policy must still
identify suitable space with privacy, lighting, and electricity that is
readily available while needed.

Milk storage is not on the mandatory equipment list. Section 39-2-216(2)
encourages facilities for milk storage. It does not convert refrigeration into
a required state-law feature.

Common questions

Does Montana require a private employer to follow the public-sector policy rule?

No. The named Montana provisions cover listed government employers. Federal
§ 218d remains the main pumping-time and space rule for covered private
employment.

Must a Montana public employer pay for the additional break?

Section 39-2-217 calls the break unpaid and says it should overlap an existing
break if possible. Federal law separately treats the time as hours worked when
the employee is not completely relieved from duty.

Is a toilet stall acceptable for a public employee?

No. Section 39-2-216 requires reasonable efforts toward a room or other nearby
location “other than a toilet stall.” The federal rule applicable to covered
employment separately excludes any bathroom.
