Background

  • Mary Herkert, a disabled employee at the Social Security Administration (SSA), served as a supervisory Branch Chief (GS-13).
  • She requested a formal scheduled telework accommodation due to her medical conditions; her request was denied, and she notified supervisors of her intent to seek EEO remedies.
  • Shortly after, Herkert was reassigned to a non-supervisory management analyst position, which allowed telework but allegedly offered less prestige and advancement.
  • Herkert filed suit, alleging disability discrimination, retaliation, and failure to reasonably accommodate under the Rehabilitation Act.
  • The district court granted summary judgment to the SSA, holding Herkert suffered no actionable adverse employment action because the reassignment was not significantly detrimental and was voluntary.
  • On appeal, the Supreme Court's intervening decision in Muldrow v. City of St. Louis lowered the threshold for what constitutes an adverse employment action.

Issues

Issue Plaintiff's Argument Defendant's Argument Held
Was the reassignment an adverse employment action? Herkert: Loss of supervisory duties was a disadvantageous change. SSA: No change in pay/benefits; reassignment was lateral. Jury must decide if Herkert's reassignment was "disadvantageous" under Muldrow standard.
Was the reassignment voluntary? Herkert: Given no choice; it was a demotion imposed due to performance. SSA: Herkert gratefully accepted the new position offered. Genuine dispute exists; jury must decide if reassignment was truly voluntary.
Did the reassignment constitute a reasonable accommodation? Herkert: Involuntary transfer to a less desirable position is not reasonable. SSA: She received requested telework in new position. District court must reconsider, as voluntariness and adversity are in dispute.
Standard for adverse action under discrimination/retaliation Herkert: No significance threshold post-Muldrow; standard is "disadvantage." SSA: Old standard required significant harm still applicable. Post-Muldrow, only "some disadvantageous change" is required for discrimination claims.
