Missouri McDonald's Worker Sues Over Age Discrimination, Alleged Workplace Abuse

The ice was just the beginning. A civil complaint filed in Barton County Circuit Court alleges that assistant managers at a Lamar, Missouri McDonald's franchise spent months targeting Tammy Deherrera, 57, after she returned from medical leave, calling her "old" and "slow," cutting her hours, assigning demeaning tasks, and, in one cited incident, dumping ice on her head.

Deherrera's lawsuit, filed April 7, 2026, alleges age and disability discrimination, hostile work environment, and retaliation under Missouri state law. The complaint contends the harassment escalated to the point of causing an acute anxiety attack that required emergency medical care, adding a medical distress claim to what is already a multifaceted employment action against the franchise operation.

The alleged conduct follows a recognizable pattern in return-from-leave cases: an employee takes medically necessary time away, returns to find the working relationship fundamentally changed, and faces a sequence of managerial decisions including reduced hours, degrading assignments, and verbal hostility that individually might be explained away but collectively form the basis of a discrimination claim. Deherrera's complaint argues that cumulative pattern constitutes illegal treatment under Missouri state law.

The case is filed against the local franchise operator, not McDonald's corporate, a distinction with direct legal consequences. Employment claims against hourly restaurant workers are routinely litigated at the franchise level, where the employer of record is an independent operator. McDonald's maintains brand and system standards, but when managers at a franchise location are accused of discriminatory conduct, the franchise owner carries the exposure. If the allegations survive discovery, the Lamar location could face damages for emotional distress, lost wages, and statutory penalties under Missouri's discrimination statute.

For managers and franchise operators, the failure points this case identifies are operational. Returning-from-leave accommodations require documented engagement, not informal tolerance. When assistant managers begin commenting on a crew member's age or physical pace after a medical absence, that is the moment legal liability starts accumulating. Reduced hours following a medical event are one of the most legible retaliation signals in employment litigation, and Deherrera's complaint names exactly that sequence.

Most state-court employment complaints of this type proceed through discovery before settling; no trial date has been set in the Barton County case. Settlement carries its own costs, including legal fees, potential damages, and scheduling disruption that any franchise running on tight margins can ill afford.

What Deherrera's complaint illustrates is that the documentation strengthening a discrimination case has to be assembled before a lawyer gets involved: specific dates, direct quotes, witness names, and records of any medical treatment sought. Missouri's civil rights agencies and the federal EEOC accept complaints when internal franchise channels are unresponsive.
