The last 35 years have been disastrous for American unions. The percentage of the workforce represented by unions has declined from about 30% to barely 10%. As the unionized island in the center of the workforce has shrunk, every element of labor relations affected by unions - job security, promotions and lay-off, job descriptions, wages and benefits (pensions, vacations, health care, etc.), grievance procedures, attention to safety - has slid away from workers. There has been a similar deterioration in union influence in electoral politics and public debate about key issues.
