I don't see any reason to get a lawyer involved. They've paid him everything they owed him for the work he's done so far. They've made him a bad offer for the future (crap salary plus crap working conditions) that he would be very unwise to take, but there's nothing illegal about making a bad offer, any more than it would be illegal for him to offer to work for a million dollars an hour. He just needs to make it clear that he's not willing to work for them unless he gets either good pay or good working conditions.
