A former broker at Morgan Stanley has filed a class-action race-discrimination complaint against the company, accusing it of making “an end-run around the civil rights laws” with a new policy that bars employee participation in class actions and forces civil rights claims into private arbitration.

Kathy Frazier said in her complaint that African-Americans were underrepresented in the ranks of brokers at Morgan Stanley and were paid “substantially less” than their counterparts.

Ms. Frazier previously worked at Goldman Sachs and Merrill Lynch and has an economics degree from Amherst College and a master’s degree in business administration from the University of Pennsylvania’s Wharton School of Business.
