A report by Jane McAlevey and Abby Lawlor, illustrates best practices for building the power to win in today’s challenging union climate and features a series of case studies in collective bargaining during the four years under Trump. They cover four key employment sectors: teachers, nurses, hotel workers, and journalists. In each case, workers used high transparency and high participation approaches in contract campaigns to build worker power. Each victory points a path to raising workers’ expectations of what is possible to win at the negotiations table today.
