  "scope_note": "48 hours as a 17-week AVERAGE, so a 60-hour week breaks nothing on its own. It is the one working-time limit with an INDIVIDUAL opt-out: since SI 1999/3372 the paragraph applies unless the employer has the worker's written agreement to work beyond it, and regulation 4(2) then requires up-to-date records of who has agreed. Regulation 25A(1) substitutes 52 hours for the 48 in the doctors-in-training modification it describes, which is a different figure and a spent one. The night worker's separate eight-hour average is `employment.working_time.night_work_limit_hours`, and a young worker's hard 40-hour week is `employment.working_time.young_worker.max_weekly_hours`.",
