Montana has no general law regarding meal and rest period but does require employers in certain professions to provide a specified number of hours off before an employee can return to work. The rights of breastfeeding mothers are also protected in Title 50, Chapter 19 of the Montana Code Annotated.

50-19-501. Nursing mother and infant protection.

(1) The Montana legislature finds that breastfeeding a baby is an important and basic act of nurturing that must be protected in the interests of maternal and child health and family values. A mother has a right to breastfeed the mother's child in any location, public or private, where the mother and child are otherwise authorized to be present, irrespective of whether or not the mother's breast is covered during or incidental to the breastfeeding.

(2) A unit of local government may not prohibit breastfeeding in public by local ordinance.

(3) The act of breastfeeding may not be considered:

(a) a nuisance as provided in Title 27, chapter 30;

(b) indecent exposure as provided for in 45-5-504;

(c) sexual conduct as defined in 45-5-620(1)(f); or

(d) obscenity as provided for in 45-8-201.
