  "scope_note": "An average of eight hours per 24, for a NIGHT worker as regulation 2(1) defines one — not a limit on any individual shift, and not the 48-hour weekly limit in regulation 4(1), which is a separate figure. Unlike the 48-hour limit there is no individual opt-out: regulation 6 may be modified or excluded only by a collective or workforce agreement (reg 23) or by the Part 3 exceptions. A young worker's night work is prohibited outright by regulation 6A rather than limited, so this figure does not apply to one.",
