Final answer:
U.S. unions offer both positive and negative outcomes for workers.
Step-by-step explanation:
In terms of pay, benefits, and hiring, U.S. unions offer a good news/bad news story. The good news for unions and their members is that their members earn about 20% more than nonunion workers, even after adjusting for factors such as years of work experience and education level. The bad news for unions is that the share of U.S. workers who belong to a labor union has been steadily declining for 50 years. In the mid-1950s, about one-quarter of all U.S. workers belonged to a union, but now only about 11.1% of U.S. workers are union members today, and if you leave out government workers, only 6.6% of the workers employed by private firms now work for a union.
