U.S. Labor Secretary Hilda Solis and Patricia Shiu, director of the labor department’s Office of Federal Contract Compliance Programs, will host a conference call Thursday morning to “announce the settlement of a significant case involving systemic hiring discrimination” that involves the ground delivery unit of FedEx.

FedEx on Wednesday acknowledged reaching a $3 million settlement with the Labor Dept. to settle allegations that the company discriminated against thousands of prospective employees at FedEx facilities across multiple states.

That number of job seekers allegedly discriminated against by FedEx tops 21,000, according to The New York Times.

Shiu told the NYT the settlement with FedEx is her office’s largest since 2004. She also told the paper her office first turned up evidence of bias 7 years ago during a normal review of the company. And that review found discrimination against several minority groups including blacks, Hispanics and Asian-Americans, in addition to women who were sometimes automatically passed over for jobs that required lifting heavy objects, according to the paper.
