The weekly limb is `employment.working_time.young_worker.max_weekly_hours`; a young worker's night work is prohibited outright by regulation 6A rather than limited.",

The evidence is the pair: the 1998 Regulations' current view and SI 2002/3128 as made, both hashed and recomputed at Gate 2. Nothing preceded this value: before 6 April 2003 the Regulations set no limit on a young worker's hours at all. The locator token is \"eight hours a day\" and not the host's run-together serialisation of paragraph (1), because a token has to satisfy the setter's document too.",
