CSC Computer Science Limited v CL Hampson
[2023] EAT 88
Equal pay legislation (Equality Act 2010, sections 64-70) requires comparison of like work and consideration of material factors justifying pay differences.
Equality Act 2010
A material factor defence is successful if the difference is due to a material factor that does not involve direct sex discrimination and is a proportionate means of achieving legitimate aims.
Equality Act 2010, section 69
For constructive dismissal, there must be a fundamental breach of contract.
Case law on constructive dismissal
Objective justification requires showing the measure is reasonably necessary and proportionate to achieve a legitimate aim; not that no other way was possible.
Bilka-Kaufhaus GmbH v Weber Von Hartz [1986] ICR 317, Bank Mellat v HM Treasury (No 2) [2013] UKSC 39
Appeal dismissed.
The tribunal did not err in finding that the material factor defence applied, even though comparators did not fully maintain operational competence during secondments. The tribunal’s consideration of the HOST exercise and its findings on proportionality were not erroneous.
Equal pay claim failed.
The tribunal found that while the claimant and her comparators performed like work, differences in pay and conditions were justified by material factors that were a proportionate means of achieving legitimate aims (maintaining an effective fire service and rewarding employees for on-call and operational readiness).
Constructive unfair dismissal claim failed.
The tribunal found no fundamental breach of contract, neither of an implied equality clause (because the equal pay claim failed) nor the implied duty of trust and confidence.
