OHS management-system worker coverage
Measurement answer
What this metric measures
Number and source-reported percentage of the named worker population covered by an occupational health and safety management system, with legal or recognized-standard basis and audit or certification states retained separately.

Reporting boundary
Preserve the named eligible population and headcount basis. Assurance states can overlap and are not additive. Parent and component populations are alternative views, not components to sum, and source-reported percentages are never averaged.

Unit meaning: This metric is reported as a structured table; each field carries the unit stated in the table fields below.
Table fields and units
- Covered workers — people headcount covered by the named system and assurance profile
- Eligible workers — people headcount in the explicitly named denominator population, when documented
- Coverage percentage — source-reported percent of the named eligible worker population using the declared headcount basis
- Worker population, legal or recognized-standard basis, audit or certification state, site scope, exclusions, and reporting date
Published dimensions
- System, internally audited, externally audited, or certified coverage state
- Employee, controlled non-employee, non-employee in own workforce, or combined population
- Legal requirement, recognized standard, named guideline, audit type, and audit date
- Eligible population, exclusions, site, activity, and workplace scope
- Reporting date, source profile, and assurance status

Variables
| Symbol | Variable | Definition | Unit |
|---|---|---|---|
N | qualifying numerator | Qualifying observations within the qualifying population and boundary defined for OHS management-system worker coverage. | Dimensionless |
D | declared denominator | Complete compatible denominator for the qualifying population and boundary defined for OHS management-system worker coverage. | Dimensionless |

Evidence and status sources
Sustopedia checked each record-specific claim directly against primary publisher material. Labels distinguish current measurement authority from future compatibility and corroborative, legal, edition, or method status context. Corroborative evidence can support a stated limitation but cannot establish the core measurement by itself.

Method disclosures required
Source-edition basis: Binding consolidated ESRS S1-14 and effective GRI 403: 2018 use different worker populations; adopted-pending ESRS remains compatibility context.
- Name the eligible worker population, covered and eligible headcounts, and headcount rather than FTE basis where required.
- State the legal or recognized-standard basis, named system, assurance state, audit type and date.
- Identify exclusions, reasons, sites, activities, workplaces, reporting date, source profile and edition.
- Do not add overlapping assurance states or parent and component populations, and do not average percentages.
Record-specific limitations
- Coverage does not demonstrate system effectiveness, legal compliance, low injury risk or equivalent assurance.
- ESRS and GRI worker-population boundaries differ.
- Excluded high-risk workers can distort a headline percentage.
Interpret this metric with the stated reporting boundary, period convention, value shape, and unit. Results prepared with different boundaries or conventions may not be directly comparable.
Measurement evidence supports the core record-specific claims described above. Corroborative evidence can support limitations, while compatibility and status sources provide their separately labelled context. None of these cards by itself determines an organisation's legal applicability, filing readiness, assurance status, or compliance conclusion.
