Breeden: Retaliation Requires Protected Opposition and Evidence of Causation

By Aneeta Mishra and Timothy Chan

Published August 23, 2026

Clark County School District v. Breeden involved a supervisor’s isolated reading of a sexually explicit statement from a job-applicant file and a later transfer decision whose planning predated the employee’s lawsuit.

Opposition must rest on an objectively reasonable belief

The anti-retaliation rule protects opposition to conduct reasonably believed unlawful, but no reasonable person could view the isolated meeting incident described as severe or pervasive Title VII harassment.

Context mattered to the incident

The statement appeared in a work-related review of an applicant’s psychological file; the Court assessed the participants’ reactions and the single occurrence rather than treating offensive words alone as dispositive.

Knowledge must precede retaliatory action

An employer cannot retaliate based on activity unknown to the relevant decisionmaker, and evidence showed the transfer process was contemplated before notice of the suit.

Timing alone was too weak on this record

A substantial gap and preexisting planning did not establish causation. Other cases may involve different timing, knowledge, or intervening evidence.

Key takeaways

• Identify the precise protected complaint and why it was reasonable.
• Establish when each decisionmaker learned of it.
• Preserve planning records predating the complaint.
• Evaluate the full causal record rather than timing alone.
