Highland Council v TGWU Unison: Requiring Consistency in Comparator Specification for Equal Pay Claims

Introduction

The case of Highland Council v TGWU Unison First & Ors [2007] UKEAT 0020_07_1812 was adjudicated by the United Kingdom Employment Appeal Tribunal (EAT) on December 18, 2007. This pivotal case revolved around numerous equal pay claims lodged against Highland Council, a local authority entity. Represented by Stefan Cross, Solicitors, the claimants sought to assert that they were not receiving equal pay compared to their male counterparts performing equivalent or lower-rated jobs as defined under the Equal Pay Act 1970 (the 1970 Act). A critical issue in this case was the adherence to statutory grievance procedures stipulated under the Employment Act 2002 (the 2002 Act), particularly concerning the specification of comparators in grievance letters versus Employment Tribunal (ET1) forms.

Summary of the Judgment

The Employment Tribunal, presided over by Miss FCC Carmichael, initially upheld the claimants' submissions, recognizing that the grievances filed met the procedural requirements under the 2002 Act. However, the respondents (Highland Council and others) appealed this decision, contending that the Tribunal erred by not conducting a qualitative assessment of whether the comparators listed in grievance letters were materially consistent with those in ET1 forms. The EAT found merit in the respondents' arguments, concluding that for an equal pay claim to be valid, the comparators identified in grievance documents must not be materially different from those presented in ET1 forms. Consequently, the appeal was upheld, and the case was remitted back to the Employment Tribunal for reconsideration in light of this legal interpretation.

City of Edinburgh Council v Mrs C Marr & Ors; Amey Services v Mrs G Cardigan & Ors: Highlighted the necessity of a comparative exercise in equal pay claims.
Shergold v Fieldway Medical Centre [2006] IRLR 76, Canary Wharf Management v Edebi [2006] IRLR 416, and Alexander and another v Bridgen Enterprises Ltd [2006] IRLR 422: Explored the scope and flexibility of grievance procedures under the 2002 Act.

These cases collectively underscored the importance of precise and consistent comparator specification in grievance procedures to ensure fair and effective resolution of equal pay disputes.

Legal Reasoning

The EAT meticulously dissected the Employment Tribunal's approach, identifying a misalignment in understanding the application of section 32(2) of the 2002 Act. The core of the Tribunal's error lay in its failure to perform a qualitative assessment of comparators across grievance and ET1 documents. The EAT emphasized that:

**Comparator Specification is Fundamental:** In equal pay claims, specifying a comparator is not merely procedural but central to establishing the claim's validity.
**Consistency Between Documents:** For a grievance to align with subsequent tribunal claims, the comparators must be materially consistent to avoid procedural bars under the 2002 Act.
**Employer's Right to Fair Notice:** Employers are entitled to clear and specific information about grievances to effectively respond and engage in dispute resolution.
**Impact on Procedural Efficiency:** While recognizing potential increases in administrative burdens, the EAT maintained that compliance with statutory procedures is non-negotiable.

Ultimately, the EAT ruled that failing to maintain consistency in comparator specification could render an equal pay claim invalid under the prescribed statutory framework.

Impact

This judgment establishes a significant precedent in equal pay litigation, particularly concerning the procedural requirements of grievance documentation. The key impacts include:

Enhanced Scrutiny of Grievance Documentation: Employers can expect rigorous examination of grievance letters to ensure comparators are clearly and consistently specified.
Clarification of Procedural Barriers: The ruling delineates the boundaries of procedural compliance, reinforcing that failure to adhere can preclude valid claims.
Guidance for Legal Practitioners: Solicitors and legal advisors must ensure that grievance procedures are meticulously followed, with comparators adequately detailed to withstand judicial scrutiny.
Potential Increase in Litigation Complexity: The necessity for consistent comparator specification may lead to more complex and demanding litigation processes for claimants.

Overall, the decision fortifies the procedural integrity of equal pay claims, ensuring that both employers and employees engage with a clear and equitable framework for dispute resolution.

Complex Concepts Simplified

Comparator in Equal Pay Claims

A comparator is a male employee performing the same or equivalent job as the claimant. Identifying the correct comparator is crucial because the claim hinges on comparing the claimant's pay to that of the comparator to establish if there is a pay disparity.

Grievance Procedure under the Employment Act 2002

This is a mandated process that employees must follow before taking their complaint to an Employment Tribunal. It involves formally lodging a complaint (Stage 1 grievance) with the employer, who then has a chance to resolve the issue internally.

Section 32(2) of the Employment Act 2002

This section mandates that a claimant must formally present their grievance in writing to the employer before escalating it to an Employment Tribunal. Failure to comply can prevent the claim from being heard.

Qualitative Assessment

This refers to a detailed evaluation of whether the comparators listed in the grievance are sufficiently similar to those in the subsequent ET1 form. The assessment determines if any differences are significant enough to impact the validity of the claim.

Conclusion

The Highland Council v TGWU Unison judgment underscores the paramount importance of procedural compliance in equal pay claims. By mandating that comparators in grievance letters must be materially consistent with those in ET1 forms, the EAT ensures that equal pay disputes are grounded in clear, comparable evidence. This decision not only fortifies the procedural framework governing equal pay claims but also safeguards both employers' and employees' rights to engage in fair and informed dispute resolution. Legal practitioners must heed this precedent to effectively navigate the complexities of equal pay litigation, ensuring that all procedural requirements are meticulously satisfied to uphold the integrity of the legal process.
