This question has been addressed in 1 Texas court opinion:
COA12 — January 30, 2026
John Campbell, a radiologist, sued his former employer for breaching a non-disparagement clause in their separation agreement after he was passed over for a job at a different medical group. Campbell alleged that a negative comment regarding his "personality issues" from a former partner caused him to lose the position. The Twelfth Court of Appeals affirmed a no-evidence summary judgment against Campbell, ruling that he failed to prove causation. The court found that Campbell's theory relied on "inference stacking"—the speculative assumption that he would have successfully completed a multi-step interview process and received a unanimous hiring vote but for the alleged disparagement.
Litigation Takeaway
“To recover damages for the breach of a non-disparagement clause, it is not enough to prove a negative comment was made; you must provide direct evidence that the disparagement was the 'but-for' cause of a lost job or contract, rather than relying on a chain of speculative inferences about a third party's hiring process.”
