Domestic staff and household contractors have legitimate access to the most sensitive areas of an executive's life (residence interior, family schedules, financial documents, communication patterns) and represent one of the highest-conviction insider-threat vectors when relationships sour or vetting is inadequate. This report sets out the household-insider framework in your chosen jurisdiction and industry: the documented insider-threat patterns from staff and contractors, the legal framework around employment-law-compliant vetting, monitoring and dismissal, the early indicators that warrant escalated attention, the operational mitigations that materially reduce exposure (vetting standards, employment contracts, NDAs, access compartmentalisation, exit protocols, ongoing-monitoring discipline), and the trigger points at which to engage a household-security or employment counsel.
