Interfaith Worker Justice (IWJ) was a nonprofit and nonpartisan interfaith advocacy network comprising more than 60 worker centers and faith and labor organizations that advanced the rights of working people through grassroots, worker-led campaigns and engagement with diverse faith communities and labor allies.

The group changed its name to Interfaith Worker Justice in 2005, by which time it had grown to 59 local affiliates and a full-time staff of 10.

It took a lead role in criticizing Wal-Mart for forcing employees to work off the clock, not providing affordable or comprehensive health insurance, and refusing to pay an adequate wage.

[7] In 2006, the group sued the United States Department of Labor to obtain the names of migrant agricultural workers who had been victims of unpaid overtime.

The organization recognized the accomplishments of unions such as the eight-hour workday, social security, anti–child labor laws and the minimum wage and seeks to advance their interests, as they have proven to be the best way for workers to get fair treatment.

More than 11 million undocumented people are living in this country, including children raised as Americans and workers who have become an integral part of the US economy.

Without legal status, immigrant workers are victims of every kind of labor abuse and cannot protect their rights without fear of deportation.

Interfaith Worker Justice was a major proponent of the Fight for 15 movement which calls on the government to raise the federal minimum wage to fifteen dollars an hour.

Research shows that raising the federal minimum wage would mean a financial lift for nearly 30 million working Americans, no effect on the unemployment rate, a more stimulated economy, and a boost in public health.

[17] IWJ was active in multiple campaigns targeting well known corporations that have standardized poor working conditions, low pay and stifling collective bargaining rights.

To become a Worker Justice Runner, athletes are asked to donate the funds raised in their next fun run, marathon or triathlon to IWJ.
