Unionized Southwest baggage handlers in Illinois do not wish to have their claims regarding biometric law violation be decided through the arbitration process. The workers claim that because Southwest keeps their work time through a fingerprint-based system, the Illinois biometric law has been violated. However, because their collective bargaining agreement does not mention the timekeeping system, the workers do not want this issue to go to arbitration.
