Figures are the total award recorded across cases that include a trade union claim and a published remedy — 33 of 473 trade union cases. Many tribunal judgments decide liability only, with compensation set at a later hearing, so they are not counted here. A judgment combining several claim types contributes its whole award. Nothing here is legal advice or a prediction of any individual outcome.

Methodology

Cases on this page are identified by first-pass extraction against the locked §4.4 claim-type taxonomy — a judgment enters the trade union caseload if trade unionis tagged in its classification output. A single judgment frequently combines multiple claim types, so the same case may appear on more than one claim-type page. Per-claim outcomes come from the second-pass (LLM-assisted) extraction and are recorded for each claim a judgment decides; the success rate counts only claims a tribunal decided on the merits (upheld or dismissed). Award figures are taken from the remedy section of each judgment where present; cases without a quantified award — because the tribunal only determined liability, or because the remedy hearing is pending — are excluded from the compensation figures. Regional splits follow the tribunal's jurisdiction as recorded on gov.uk. Nothing on this page is legal advice or a prediction of any outcome; for any specific matter the gov.uk judgment PDF linked from each case page is the authoritative source.
