A federal judge has dealt a blow to women who have accused Microsoft of systematic discrimination against female employees, refusing to certify their class-action lawsuit against the company. The three named plaintiffs in the lawsuit will be able to proceed with their case. But they won't be proceeding as representatives of the broader group of women who—according to the lawsuit—have suffered from unequal pay and degrading treatment in the workplace.
