The "union advantage" is substantial.

Through unions, workers join together to win better wages, benefits and a voice on the job – and good union jobs mean stronger communities. Unions give workers a voice at work, to bargain as a group for benefits such as non-discrimination protections and domestic partner benefits. Union members earn better wages and benefits than workers who aren’t union members.

On average, union workers’ wages are 30 percent higher than their nonunion counterparts. While only 14 percent of nonunion workers have guaranteed pensions, fully 68 percent of union workers do. More than 97 percent of union workers have jobs that provide health insurance benefits, but only 85 percent of nonunion workers do. Unions help employers create a more stable, productive workforce—where workers have a say in improving their jobs.
