In recent years, in some firms and industries, unions have agreed to pay cuts and other concessions, while in some other firms and industries collective bargaining has continued as usual and produced an extension of traditional outcomes. Some of the concessionary agreements include only pay cuts or freezes while some others include union gains ("quid pro quos"). What factors explain the diverse form and scope of concession bargaining? What options do you believe to be the most beneficial to employees? Give examples where applicable.
