By now, most employers required to file an Employer Information Report EEO-1 (known as the EEO-1 Report) with the U.S. Equal Employment Opportunity Commission should have received 2015 EEO-1 filing materials in the mail. Letters are typically mailed beginning in mid-July, as the deadline for filing the survey is September 30, 2015. The EEO-1 Report is a compliance survey report that is mandated by federal statute and requires company employment data to be categorized by race or ethnicity, gender, and job category.
