In the current rapidly changing economic environment, there has been an increasing tendency since the 1990s for US employers, trade unions and workers to come together to create non-traditional structures aimed at meeting their various interests at work. More progressive companies and unions have used the collective bargaining process as a means to tackle the competitive pressures resulting from globalisation. Some have created partnerships based on new methods of communication and conflict resolution, joint decision-making in many areas, new work processes involving greater creative freedom for workers, and continuous training.
