Eight Years of Public Data From adidas Is the Clearest Answer Available to CSDDD
CSDDD doesn't ask for evidence of existence — it asks for evidence of effectiveness. Most brands fall short: channels exist, policies are written, boxes are ticked. But the data that would show whether workers are using those channels, whether complaints resolve, and whether trust is building over time is rarely collected or disclosed. Since 2017, adidas has done exactly that — making it one of the most concrete answers available to the question CSDDD is asking.
CSDDD Doesn't Ask If You Have a Grievance Mechanism — It Asks If Workers Actually Use It
CSDDD requires mechanisms that are accessible (including anonymously), trusted (workers believe raising a concern leads to a real outcome), effective (complaints resolved in a timely manner), and demonstrable through monitoring and disclosure. These requirements describe a program with measurable inputs, outputs, and outcomes — not a policy document.
One Platform, Three Systems, 400,000+ Workers, One Integrated Due Diligence System
Since 2017, adidas has deployed WOVO across 100% of its strategic Tier 1 manufacturing partners — reaching 400,000+ workers across up to 17 countries annually. Three CSDDD-relevant components: the WOVO grievance mechanism, the Worker Pulse survey (biannual, rights-focused), and targeted surveys on specific rights issues including gender equality. All three feed into adidas' human rights due diligence systems and supplier S-KPI ratings.
The Full Record: Grievances, Resolution Rates, and Satisfaction From 2019 to 2025
100% Tier 1 Coverage, Every Year — Coverage Has Never Been the Gap
adidas has maintained 100% Tier 1 coverage every year with access consistently above 400,000 workers across multiple countries — even as its value chain consolidated. Coverage has never been the gap. What the data shows is whether the mechanisms behind that coverage are working.
99% Resolution Rate, Held at Scale: The Floor, Not the Ceiling
Resolution rate has held at 99% every year since 2021. This is the most basic measure of whether a grievance mechanism functions at all — and it is also the floor. A 99% resolution rate tells you complaints are being processed. Satisfaction and response time tell you whether they are being processed well.
39% to 79% in Six Years: Satisfaction Gains at This Scale Don't Happen by Accident
Worker satisfaction with complaint resolution has risen 40 points over six years, with gains in almost every year. This is the metric CSDDD cares about most and that most brands have the least data on. A mechanism that resolves complaints on paper but leaves workers dissatisfied is not providing meaningful access to remedy.
Response Times Fell 80%: Workers Now Hear Back in Under Half a Business Day
Average response time fell from 49 hours in 2020 to under 11 hours in 2025 — a reduction of nearly 80%. Workers are not just getting responses; they are getting them fast enough to matter.
Volume Dropped, Then Jumped 32%: What the Rebound Actually Measures
Volume reflects both program maturity and value chain size. As adidas consolidated its supplier base, fewer facilities produced fewer absolute grievances. The 32% rebound to 47,200 in 2025 — against further facility reduction — is the meaningful signal: more workers per facility chose to use the system. That is the clearest evidence of growing trust.
Reactive Isn't Enough: How Worker Pulse Meets CSDDD's Stakeholder Engagement Requirement
The Worker Pulse now runs across 96 facilities in 13 countries, with favorable responses rising from 78% to 91% since 2020. CSDDD's stakeholder engagement requirements go beyond reactive grievance handling — brands must proactively engage workers to understand their experiences and risks. The Gender Equality survey (51,000 workers, 87/100 in 2025) demonstrates the same infrastructure can target specific rights categories.
Three Things Eight Years of adidas Data Proves — That Most Brands Haven't Learned Yet
Effectiveness is built, not installed. The improvement from 58% satisfaction in 2020 to 79% in 2025 happened because adidas invested consistently in supplier capability, KPI tracking, and worker communication over years — not because the platform was deployed.
The metrics that matter most are the ones most brands don't collect. Resolution rate is table stakes; satisfaction, response time, and sentiment trends are what regulators will ask for.
Coverage and integration are separate problems. 100% Tier 1 coverage is a coverage achievement. WOVO data feeding into S-KPI ratings and due diligence priorities is an integration achievement. CSDDD requires both.
CSDDD Compliance Isn't Built at Deadline. It's Built Over Years.
Eight years of publicly disclosed data makes a clear case: technology-enabled worker engagement, consistently governed and properly integrated into due diligence systems, produces measurable, compounding improvements in the outcomes CSDDD demands. Satisfaction doubles. Response times fall 80%. Coverage scales to hundreds of thousands of workers without quality erosion. The brands that will find CSDDD compliance straightforward are not the ones with the simplest value chains — they are the ones that started building their evidence base early.
