Decades-old time off given women for pregnancy leave cannot be counted when deciding pension eligibility, the Supreme Court decided Monday. The ruling is a setback for a relatively small class of women, many in or approaching retirement, who took maternity leave before a federal law went into effect prohibiting workplace discrimination. That 1979 statute, the Pregnancy Discrimination Act, said companies had to treat such time off just like any disability, and it would be credited toward retirement.
