Regulation 7(5) ends it at a dismissal. SI 2002/2789 reg 8(b) substituted the words and came into force on 24 November 2002 (reg 1(1)), but its regulation 2(1) gives the maternity amendments effect \"only in relation to employees whose expected week of childbirth begins on or after 6th April 2003\" — which is the date this record carries.",

    "scope_note": "READ THIS BEFORE USING THE FIGURE: 26 weeks is the SECOND half of statutory maternity leave, not the whole of it. The first half is `employment.leave.maternity.ordinary_weeks` (regulation 7(1), also 26 weeks) and the 52-week total is the derived `employment.leave.maternity_weeks`. Maternity PAY runs 39 weeks (`employment.smp.paid_leave_weeks`), so roughly the last 13 weeks of this period are unpaid; the two compulsory weeks after childbirth are `employment.leave.compulsory_maternity_weeks`.",
    "notes": "An SI carry (ADR-0014): SI 2002/2789 reg 8(b) substituted the WORDS \"29 weeks beginning with the week of childbirth\" with \"26 weeks from the day on which it commenced\", and it is that substituted phrase which is the locator — verbatim in the setter's as-made text and, as it happens, unique in the host. That coincidence is exactly what its sibling lacks: reg 8(a) substituted only \"26 weeks\" into paragraph (1), three provisions of the host share those words, and a locator long enough to be unique there is longer than anything the setter wrote. `si_probe` uses ONE token set for the host's uniqueness test and the setter's presence test, so this row's sibling cannot be carried at all — it is authored instead as an NF-1 derivation from the same instrument's own substituted words (2026-09-14), which needs no host locator. Whether the probe should take a separate setter-side token set remains a design question, recorded rather than worked around.",
