Article 4(1): employers must have pay structures ensuring equal pay for equal work or work of equal value.
Article 4(2): Member States must make analytical tools and methodologies accessible to support gender-neutral job evaluation.
Article 4(4): pay structures must enable assessment of whether workers are in a comparable situation. Criteria must not be based on sex and must include skills, effort, responsibility, and working conditions. Relevant soft skills must not be undervalued.
REF™ is an eight-factor methodology engineered to satisfy Article 4(4). The four mandatory criteria are directly present:
- Skills: F-02 Knowledge Depth and F-07 Innovation Requirement.
- Effort: F-03 Problem Complexity.
- Responsibility: F-01 Organisational Impact, F-04 Decision Autonomy, F-05 People Leadership.
- Working conditions: F-08 Working Environment.
F-06 Influence and Communication is the "other factor relevant to the position" that Article 4(4) expressly permits. Every factor has documented gender-neutrality rationale.
REF™ Methodology Role Evaluator Compare RolesArticle 4(4) requires that the criteria be agreed with workers' representatives where such representatives exist. Vareqa produces the methodology documentation and the factor-by-factor rationale, but the consultation with works councils or union representatives is the employer's process and should be documented by HR. Where no representatives exist, this is a null requirement.
