Issue 3, 15/09/2026 — persons at risk corrected

Issue 2 described the office administrator post as currently vacant. That was wrong on both counts. Joanne Graham has been the Admin Assistant throughout, and Laura Walden joined on 8 June 2026 as Finance & Compliance Assistant — an additional role, not a replacement. The post was never vacant; the assessment described a vacancy that did not exist while omitting a second person who did. Both are now named as persons at risk. No control, score or action changed — the exposed population is the same and is now described accurately. The review anniversary is unchanged at 04/09/2027.

Task/Activity

Handling, storing and disposing of confidential information — employee and subcontractor personal data, right-to-work documents, training certificates, payroll records, and customer commercial information held under framework agreements.

Location

Northampton Office (Unit 1), Unit 2C Stour Road, home working locations and AMWS cloud storage.

SLRSLR
Employee or subcontractor personal data exposed — right-to-work documents, training certificates, payroll recordsHeld in the HR folder on Microsoft 365 with role-based access (POL_HSQE_30 Section 1); PROC_R2W_01 Right to Work procedure governs collection and retention; POL_HSQE_09 Data Protection326HR folder access limited to the Directors and confirmed at the September Management Review access review, so the restriction is evidenced rather than assumed212
Customer commercial information shared more widely than neededCustomer-system access by individual named credentials, never shared (POL_HSQE_30 Section 7); no bulk export of customer data to local storage326Sharing links set to named recipients rather than anyone-with-the-link, as under RA_HO_02212
Paper records containing personal data left accessible in the officePremises secured out of hours; the IMS portal is the master record, local copies are working copies only, and paper originals are limited to HR right-to-work and payroll files held in the locked HR cabinet236End-of-day habit of clearing anything containing personal data from desks. The confidential-waste route is not currently recorded — confirm and document it, whether an on-site cross-cut shredder or a confidential-waste collection (Leanne Mason, by 31/12/2026)224
Confidential conversation overheardSmall office with few visitors; HR, payroll and disciplinary conversations held privately or by phone from a closed room224None — proportionate to the premises and the number of people present224
Screen contents visible to a visitor or in a public placeLaptops locked when unattended (POL_HSQE_30 Section 5); very little desk working is done in public places or on customer premises224None. Privacy filters would be disproportionate to the amount of public working actually done224
Loss or theft of a device holding personal dataFull-disk encryption on company laptops via BitLocker / FileVault; screen locks on mobiles; devices never left in unattended vehicles overnight (POL_HSQE_30 Section 5)326Remote sign-out and device-wipe capability confirmed in the Microsoft 365 admin centre with the invoking authority recorded (Aaron Mason, by 31/12/2026)212
Personal data retained longer than it is neededPOL_HSQE_09 Data Protection sets the principle; right-to-work documents retained per PROC_R2W_01236Retention periods for HR, payroll and training records written down and held in the HR folder so the principle is applied consistently (Leanne Mason, by 31/03/2027)224

How this document is approved

This document is maintained under AMWS's continuous-compliance model. Substantive revisions are reviewed and signed off by the Directors at the standing weekly Director / HSQE compliance call (Sean Ashton, Onyx + Leanne Mason). Currency, cross-references and minor edits are checked at the monthly Onyx site visit. The annual Management Review (September) provides the strategic-level confirmation. Compliance is therefore continuous, not gated on a single annual meeting.
