Should employers face stricter legal standards when defining essential functions for workers with disabilities?

A federal district court in Tennessee has denied a motion for summary judgment filed by SumiRiko Tennessee, Inc. The move allows a lawsuit concerning an Americans with Disabilities Act disability discrimination claim to proceed.

Why it matters
