The Equal Employment Opportunity Commission has filed disability discrimination lawsuits in recent weeks against a trio of employers with big retail operations, moves that may signal the agency under the Biden administration is taking a tougher stance on how far businesses must go to accommodate disabled workers.

The commission in July sued Hobby Lobby and last month sued Walmart and The Salvation Army, alleging the employers failed to meet their obligations under Title VII of the Civil Rights Act to provide reasonable accommodations to disabled workers unless doing so would pose an undue hardship.
