What this is
What is a vulnerable worker register?
What is a vulnerable worker register?
It is a controlled-access log of every worker who currently has an adjustment in place — a young worker, a new or expectant mother, someone with a medical restriction or disability, a temporary or agency worker, or a worker with a language barrier. Each entry names the functional need and carries its own review date, rather than leaving the adjustment to live only in a manager's memory.
What is a 'functional need' as distinct from a medical diagnosis?
A functional need describes what changes at work — no overhead lifting, no night shifts, extra supervision during an induction period — without stating the underlying condition. The register is built to hold that operational detail only; the No Medical Detail Held control exists specifically to keep diagnoses out of a document line managers and shift planners can see.
What makes an entry 'still current' rather than needing review?
An entry is current when its adjustment has been checked against the review date and confirmed still needed and still applied, not merely when the paperwork was completed once. Still Current, Review Date and Overdue For Review work together so a lapsed check is visible at the register level, not buried inside one entry.
Scope
When is a vulnerable worker register required?
This register is one step in a larger programme. Using it for work that belongs to a neighbouring template produces records that are hard to report on later, and a register that holds the wrong kind of detail is harder to defend than one that holds too little.
Use this template when
- A worker needs an ongoing adjustment — young worker, new or expectant mother, medical restriction, disability, language barrier, or temporary or agency status — that must survive a change of supervisor or shift pattern
- HR needs one controlled-access place holding current adjustments and their review dates, separate from the personnel file and the roster
- A new entry is being added, an existing one is being reviewed and reconfirmed, or one is being retired because the need has ended
- A linked Workplace Adjustment Record has been created and needs to stay visible to whoever schedules or supervises that person
- Access needs to be limited to named individuals rather than shared on a general roster, whiteboard or spreadsheet
Do not use it for
- Young Worker Risk Assessment, which assesses the additional risk to workers under eighteen, covering inexperience, awareness and prohibited tasks.
- New and Expectant Mother Assessment, which assesses the workplace for a worker who is pregnant, has recently given birth or is breastfeeding.
- Temporary and Agency Worker Review, which reviews whether agency and short-term workers receive the same induction, training and supervision as permanent staff.
- Workplace Adjustment Record, which holds the content of the adjustment itself — this register only points to it by ID and tracks whether it is still current.
- Anything outside KnowSafe, which belongs in the workspace that owns that process.
Compliance mapping
Which ISO 45001 cl.5.4 requirements does this satisfy?
The clauses below are the ones this register actually implements, mapped to the section that carries them.
| Clause | Requirement | Where it lands |
|---|---|---|
| ISO 45001 cl.6.1.2.1 | Hazard identification must account for workers who are more vulnerable, including young, new, pregnant or disabled workers | Entries |
| ISO 45001 cl.5.4 | Workers must be consulted on decisions that affect their own health and safety information, not just informed of them | Register control |
| ISO 45001 cl.7.5.3 | Documented information containing personal welfare detail must be protected against unauthorised access and use | Register control |
| ISO 45001 cl.8.1.2 | Controls put in place to reduce risk to an individual worker must remain effective over time, not just be documented once | Entries |
| ISO 45001 cl.9.1.1 | The organization must monitor whether OH&S controls, including individual adjustments, continue to be applied | Register health |
| ISO 45001 cl.5.3 | A named role must carry responsibility for maintaining welfare and adjustment records | Header |
| ISO 45001 cl.10.2 | Where an adjustment is found not to be applied, a corrective action must be raised and tracked to closure | Register health |
What it does not cover
- An entry with no review date, which means nobody will ever be prompted to check whether the adjustment is still needed.
- A Functional Need field carrying medical detail, which breaches the No Medical Detail Held control the register exists to uphold.
- An entry marked Still Current with no matching count in Adjustments Verified In Place, which records a restriction nobody has actually confirmed is being applied.
- A register with Who Can View set to Widely available, which turns a confidential welfare list into a document anyone can browse.
- An overdue review left open across a supervisor handover, which is exactly the gap this register was built to close.
Global
Vulnerable Worker Register requirements by country
A vulnerable worker register sits across occupational health and safety law and data protection law at once, and the three instruments below carry more weight over its design than the country the company is incorporated in.
Management of Health and Safety at Work Regulations 1999, reg.16 and reg.19
Requires a specific risk assessment for new and expectant mothers and for young workers, not a generic register entry.
Category and Functional Need must trace back to an actual assessment for that worker, not a template answer copied across similar entries.
GDPR, Article 9
Classifies health-related data as a special category requiring explicit safeguards beyond ordinary personal data.
Access Restricted, Who Can View and No Medical Detail Held are not optional extras on top of the register — together they are the compliance mechanism GDPR requires.
Americans with Disabilities Act, reasonable accommodation provisions
Requires accommodations to be provided and medical information about them kept confidential and separate from ordinary personnel files.
The register's separation of functional need from diagnosis is the same separation the ADA requires between an accommodation and the medical file behind it.
How to complete it
How to complete a vulnerable worker register, step by step
Filling in every field is the mechanical part. The four calls below decide whether a completed register would survive being read by someone who was not in the room when it was written.
Enough detail has to reach a supervisor to change the roster, but not so much that Functional Need becomes a medical record. The call is worded specificity: 'no lifting over 10kg for six weeks' is a functional need; the condition that produced it is not.
Named individuals only is the strictest setting, but a supervisor who cannot see the entry cannot apply it. The call is whether Who Can View widens for a specific role, or stays narrow and pushes the adjustment out through a separate instruction instead.
A review that only checks the paperwork against the calendar is faster than one that re-engages the worker, but it also misses a need that has changed. The call is whether Still Current can ever be ticked administratively, or must always follow a conversation.
Self-reporting a control failure only works if it does not automatically become a disciplinary matter for the supervisor who admits it. The call is whether Action Required follows every honest 'Yes' the same way, or the response is calibrated to encourage the admission.
What auditors find
Most common vulnerable worker register findings
These are the patterns an auditor, or an internal reviewer doing the same job before an auditor arrives, finds on a register that looks complete at a glance.
| Finding | Clause | What fixes it |
|---|---|---|
| Entries carry a review date with no corresponding count in the register's overdue total | ISO 45001 cl.9.1.1 | Reconcile Reviews Overdue against every Entries row past its Review Date before each report, not just at audit time. |
| Functional Need text describes a diagnosis rather than a workplace adjustment | ISO 45001 cl.7.5.3 | Rewrite in adjustment terms — what changes at work, not the condition — and confirm No Medical Detail Held stays Confirmed. |
| Who Can View is set to Line managers on a register carrying pregnancy or disability entries | GDPR Art.9 | Restrict to Named individuals only for health-related categories, and record the narrower list against that entry. |
| An entry shows Still Current: Yes and Overdue For Review: Yes at the same time | ISO 45001 cl.10.2 | Treat the contradiction as its own finding, not just another line in the overdue count — an entry cannot be both current and unverified. |
| Category is Medical restriction but Adjustment Record ID is blank | ISO 45001 cl.6.1.2.1 | Do not mark the entry complete until it links to a Workplace Adjustment Record, or the blank field carries a documented reason. |
| Removal On Request Possible is answered No | GDPR Art.9 | Build a removal process before the next entry is added — a fixed 'No' should trigger its own action, not sit as a static answer. |
Case in point
Case in point: the adjustment that outlived the supervisor
A worker returning from surgery was entered on the register with a six-week no-overhead-lifting restriction, reviewed at week six and marked Still Current with a fresh review date set. Functional Need, Category and Supervisors Informed were all answered correctly, and the entry would have passed any check run against it in isolation.
Three weeks later the briefed supervisor went on parental leave and a cover supervisor took the shift without opening the register before building the roster. The worker was scheduled onto a task the adjustment excluded. The entry itself was never wrong — it simply was not read at the point the decision was made, which is the exact gap the register exists to close, and a completed-looking entry does nothing to prevent on its own.

From a document you fill in to a programme that runs itself
Filling in an entry is the easy part. Making sure the right supervisor reads it before the next roster goes out is the part that actually protects the worker.
Holds the vulnerable worker register against your actual roster, flags entries approaching their review date, and keeps the adjustment record linked rather than duplicated.
Where a medical restriction or return-to-work adjustment is assessed in the first place, feeding this register the functional need without exposing the underlying diagnosis.
Tracks which entries belong to agency or temporary labour, so a worker's adjustment travels with them across placements instead of resetting at every new assignment.

Coordinates the crew, rolls completion and exceptions into one view, and holds every write for your approval before it touches a record.
This template lives in KnowSafe — safety and compliance. Incidents, hazards, permits, inspections and the critical controls behind them.

Vulnerable Worker Register definitions and key terms
- Functional need
- The description of what changes at work for a specific worker — reduced hours, no overhead lifting, extra supervision — expressed without reference to the underlying medical condition.
- Vulnerable worker
- A worker who, because of age, a temporary or permanent condition, employment status or language, needs a specific adjustment applied and checked more often than the general workforce.
- Named individuals only
- An access setting that limits who can open a register entry to specific named people rather than a role or team — the tightest of the Who Can View options.
- Register (architecture)
- A Knowella form type that holds ongoing, currently-true records — who needs what, right now — rather than a one-off event; entries are added, reviewed and retired instead of closed once.
- Reasonable adjustment
- A change to a role, workplace or schedule that removes a disadvantage a worker would otherwise face, without imposing an undue burden on the employer — the concept most Functional Need entries are describing in practice.
FAQ
Frequently asked questions about vulnerable worker register
What is a vulnerable worker register?+
It is a register used in KnowSafe that holds the workers who currently need additional consideration, with the adjustment in place and its review date. It is built against ISO 45001 cl.5.4 and forms part of the Vulnerable and Temporary Workers programme.
Why does the register hold no medical detail?+
Access Restricted, Who Can View and No Medical Detail Held work together so the document a supervisor actually sees only ever carries a functional need, never a diagnosis. That combination keeps the register lawful under special-category data rules and usable at the same time.
How often is an entry reviewed?+
Each entry carries its own Review Date, and Still Current and Overdue For Review are set against it at the next check. Register health rolls every overdue entry up into a single workspace count, so a lapsed review is visible in a report even if nobody opens that entry directly.
Which programme does the vulnerable worker register belong to?+
It is part of Vulnerable and Temporary Workers, alongside the Young Worker Risk Assessment, New and Expectant Mother Assessment and the Workplace Adjustment Record. The outcome the programme is built for is restrictions that survive a change of supervisor, and a register that makes them visible.
Can a worker ask to be removed from the register?+
Workers Consent To Being Listed and Removal On Request Possible exist specifically to answer that. A register that answers No to removal on request has a gap that should be closed before the next entry is added, not treated as a fixed setting.
Can the template be changed?+
Yes. Every field, option, score and conditional rule is editable, and the links to other templates come with it. Most teams install it as it is, run it for a cycle, then adjust.
