Students and early‑career professionals are increasingly using ChatGPT to rehearse salary negotiations, deliver difficult feedback, and simulate managerial conversations. The practice offers a low‑risk environment to build conversational skills and emotional readiness. Deloitte and other surveys cited in coverage indicate a notable share of younger workers use AI for communication‑skill development. Career centers and professional‑development teams should integrate AI‑based roleplaying into workshops while teaching prompt craft and ethical use. Universities can turn this behavior into curricular advantage by embedding structured AI rehearsal labs in career services and communication courses, teaching students to combine metacognitive reflection with AI prompts to improve negotiation and conflict‑management outcomes.
