A federal judge in Colorado has allowed a flight attendant’s negligent-retention claim against United Airlines to move forward, finding the airline may be liable for how long it waited to act after learning a pilot was under criminal investigation for distributing intimate images of her without her consent.
According to the amended complaint and the court’s order, the flight attendant learned in mid-2024 that another United employee had reported the pilot’s conduct to law enforcement earlier that year. United itself allegedly learned of the police investigation in April 2024, but the airline did not place the pilot on leave, open its own investigation or notify the flight attendant. He was terminated only in July 2024, after his arrest. The judge dismissed the flight attendant’s hostile work environment claim, finding the airline had no way to have discovered conduct that occurred outside the workplace and was never reported internally, but let the negligent-retention theory proceed specifically for the period after United had direct knowledge from police.
The original insight for HR and legal teams is the line the ruling draws: an employer’s liability exposure did not turn on whether the underlying misconduct happened at work, but on what the company did in the window between learning about a credible law-enforcement inquiry and taking action. Two to three months of inaction after direct notice from police was enough for a negligent-retention claim to survive dismissal, regardless of whether a formal internal complaint was ever filed.
The case adds to a pattern of 2026 rulings testing how far employer liability extends when serious misconduct originates outside company walls, following this year’s broader review of how contractors and employers are held to account when paperwork and process fail and echoing the documentation gaps seen in EEOC’s disability-related settlement against Pearson Education. In both, the trigger for liability was delay after notice, not the initial incident itself.
