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, send the issue to a special committee following this year’s legislative session. The proposal faced opposition from some business groups, including the Indiana Chamber of Commerce and the Indiana Manufacturers Association.
