Artificial Intelligence (AI) is reshaping the workplace, but its use may carry risks. In an experiment, we tested reactions to an email in which an employee requested a raise, varied by disability, gender, and how the message was created (using AI, a job coach, or self-written). Emails written personally were viewed as most trustworthy and persuasive, while AI use drew the harshest criticism, over and above the use of a job coach. Mental health disability led to greater stigma than a physical disability, particularly for women. The negative reactions to AI use were so strong that they overshadowed even the disability bias. As AI becomes routine, it’s important to consider when and how it should be used, especially for tasks where a personal touch may carry more weight.
