But, "contract negotiation" is a term used mostly during the initial hiring process. It's also a term that is used in relation to high profile positions like HBD or Athletic Director. I've never heard of an AD contract being negotiated upwards in any significant amount, but I've only taught in rural-ish areas. Perhaps it happens in larger programs. The attraction for negotiating high profile positions is that the district believes the person can (or already has) delivered results. That's hard to prove or justify as an assistant. It's not that your accomplishments wouldn't be recognized internally by the HD/parents/principal, but that ultimately those results are publicly attributed to the person at the top . . . one of the many hazards of working as an assistant.
