When attorney Robert Bonsignore filed his first class action against Wal-Mart Stores in 2004, wage-and-hour claims weren't all the rage like they are now, and few attorneys wanted in on the action. Now, a federal judge has granted final approval to a settlement under which Wal-Mart will pay between $65 million and $85 million to resolve 39 consolidated wage-and-hour class actions involving more than 3 million Wal-Mart employees -- the largest wage-and-hour class on record.
