Head of Department — UK Secondary School (Mid-to-Senior): The Head of Department still teaches 60-80% of their timetable -- the most AI-resistant work in the economy -- while managing one subject team. AI is transforming the administrative and analytical layer (exam data analysis, lesson planning, marking, department reporting) but cannot teach a classroom of teenagers, mentor a struggling colleague, or lead curriculum change. 50% of work is entirely beyond AI reach. Safe for 10+ years.

School Business Manager (NASBM) (Mid-Level): The SBM's operational core -- finance, payroll, HR admin, procurement, compliance reporting -- is heavily exposed to AI automation, with 75% of task time scoring 3+. Strategic advisory, estates oversight, and senior leadership contribution provide resistance, but the transactional operations layer that defines mid-level SBM work is being transformed by AI-powered MIS, payroll, and analytics platforms. Adapt within 3-5 years.
