Fred Furth won a $172 million award two years ago for Wal-Mart employees who weren’t paid for meal breaks. But in a suit filed Tuesday, a lawyer who worked at his firm for five years accuses him of cheating her and others out of promised bonuses.

In the complaint, Carolyn Burton says she accepted a below-market salary because she was led to believe she’d be in line to earn bonuses amounting to 3 to 5 percent of the firm’s annual profits.
