Republican lawmakers on Monday threw a roadblock in front of a proposal that would require more Indiana businesses to allow pregnant women to take longer breaks, transfer to less physical work and take unpaid time off after childbirth.

The GOP-dominated Indiana Senate voted 34-15 to delete the requirement from the bill and, instead, chose to send the issue to a special committee following this year’s legislative session.

The action could stall the proposal that has been supported by Republican Gov. Eric Holcomb as a way of improving Indiana’s infant mortality rate, which was the country’s seventh-worst, and join 27 other states with similar laws. The new state law would’ve applied to businesses with more than 15 employees and would require them to provide workplace accommodations to pregnant women that do not cause what was called an “undue hardship” on the company.

Federal laws already require larger companies to provide pregnancy accommodations, but top Holcomb administration health officials joined several doctors and other health advocates last week in testifying in support of state requirements.

A few dozen activists gathered on Monday at the Statehouse calling on lawmakers to support the accommodations requirement as a way of helping pregnant women who do not face clear rules in the workplace.
