ESRS S1-5 Collective Bargaining
ESRS S1-5 requires companies to disclose the percentage of employees covered by collective bargaining agreements and how the company engages with workers on sustainability topics. For European companies, collective bargaining coverage is often high through sector-wide agreements — but correctly calculating and disclosing coverage across multiple jurisdictions requires careful methodology.
ESRS S1-5 requires companies to disclose the percentage of employees covered by collective bargaining agreements and how the company engages with workers on sustainability topics. ESRS S1-5 requires disclosure of:.
What ESRS S1-5 requires
ESRS S1-5 requires disclosure of:
Collective bargaining coverage: The percentage of total employees whose terms and conditions of employment are determined by collective bargaining agreements — broken down by country where significant variation exists.
Social dialogue structures: A description of the governance structures for worker representation — works councils, trade union recognition, European Works Council (EWC) for groups with 1,000+ employees in two or more EU member states, and other collective representation mechanisms.
Sustainability information sharing with workers: How the company informs and consults workers on sustainability topics — specifically whether and how workers or their representatives are involved in the company's sustainability governance and decision-making processes.
Health and safety worker representation: Whether health and safety matters are addressed through formal worker representation — joint H&S committees, safety representatives with inspection rights, and consultation on H&S policy.
The disclosure connects two distinct obligations: the quantitative CBA coverage metric (what percentage of workers have collectively bargained terms); and the qualitative social dialogue description (how the company structures its relationship with worker representatives beyond formal CBA).
Calculating collective bargaining coverage accurately
Collective bargaining coverage calculation is more complex than it appears — particularly for multinational companies where CBA structures vary significantly between countries.
National vs company-level CBAs: In many European countries (Germany, France, Netherlands, Italy, Nordics), sector-wide collective agreements apply to all workers in a sector regardless of whether their employer has directly negotiated with unions. A German manufacturing company's workers may be covered by the metal workers' sector agreement (IG Metall Tarifvertrag) even without a company-level union agreement. Include workers covered by sector-wide CBAs in the covered percentage — not just company-level agreements.
Partial coverage within a workforce: Some employees may be in covered roles (production workers covered by manufacturing CBA) while others are not (management, professional staff not covered by the same CBA). Calculate coverage as: employees whose terms are determined by a CBA ÷ total employees × 100. Where a CBA covers all terms for some employees and only specific terms (minimum wages, working hours) for others, apply professional judgement on whether 'covered' is the right characterisation.
Geographic variation: CBA coverage varies dramatically between countries — Nordic countries (90%+), Germany and France (60–80%), Southern Europe (variable), and non-EU countries (often very low or zero). For multinational companies, provide country-level breakdown where variation is significant — a single global percentage is misleading when it averages 95% European coverage with 0% US coverage.
For the first disclosure: extract CBA information from your HR data for each country. Cross-reference with employment law counsel in each jurisdiction to identify which collective agreements apply. Aggregate to a total covered percentage and document the methodology.
European Works Councils — the pan-European social dialogue obligation
Companies with 1,000+ employees in EU member states, including at least 150 employees in each of two or more EU countries, are required to establish a European Works Council (EWC) under EU Directive 2009/38/EC.
EWC obligations: Consult and inform the EWC on transnational matters affecting the company's workforce — restructurings, major changes to production, collective redundancies, mergers, and sustainability topics affecting working conditions.
For ESRS S1-5 disclosure: describe your EWC structure — number of employee representatives, countries represented, meeting frequency, and topics discussed. Disclose whether sustainability topics are included in EWC information and consultation — this is increasingly expected as sustainability affects working conditions and long-term employment.
CSDDD interaction: CSDDD requires companies to consult with worker representatives in the design of their human rights due diligence programmes. For companies with EWCs, the EWC is the natural forum for this consultation — document EWC involvement in CSDDD due diligence design as evidence of both CSDDD compliance and ESRS S1-5 social dialogue disclosure.
For companies without an EWC: if you meet the threshold, the absence of an EWC is a legal violation in addition to a governance disclosure issue. Check with employment law counsel whether your company structure triggers EWC obligations.
Frequently asked questions
Do we include workers covered by sector agreements they are not aware of?
Yes — CBA coverage is an objective legal status, not a worker's subjective awareness. Workers whose minimum terms are legally determined by a sector collective agreement are covered by a CBA whether or not they know it. Include all workers whose minimum wage, working hours, or other key terms are set by any form of collective agreement — sector-wide, company-level, or establishment-level.
How do we handle countries where collective bargaining is legally restricted?
Some countries restrict or prohibit certain forms of collective bargaining. Disclose the legal context — note that CBA coverage is zero in specific countries due to legal restrictions, not due to employer policy. For countries where collective bargaining is permitted but not practised, disclose the reason — lack of union organisation, workforce preference for individual contracts, or other factors.
What if our employees are actively anti-union?
Freedom of association includes the right not to join a union. Where employees in countries with full freedom of association have not organised or have chosen not to be covered by CBAs, the zero coverage is a legitimate outcome. Disclose accurately — zero CBA coverage in a jurisdiction with full freedom of association is different from zero coverage due to legal restriction or employer interference.
