The Obama administration is expected soon to decide whether to increase the number of salaried workers eligible for overtime pay. The move could mean more money in workers' pockets. But some policy experts say the change will have negative effects on businesses. Most workers who are paid on a salary basis - instead of by the hour - do not receive overtime pay for the extra hours they put in. They're called "exempt" employees. They're "exempt" because of their executive, administrative or professional status. They're supervisors, company decision-makers, experts of their field.
