Reform UK has published proposals for a 'Women and Motherhood Protection Act' that would codify existing maternity rights and extend the window for filing pregnancy and maternity-related unfair dismissal claims from three months to 12 months. This procedural change matters because many pregnant workers and new mothers miss the current three-month deadline while managing leave and newborn care simultaneously.

The Trades Union Congress responded sharply. It characterised the proposals as a "shameless and deceptive" attempt to distract from what the TUC describes as Reform's broader policy platform that would reduce women's employment protections overall. The union federation did not enumerate which specific Reform policies it views as most damaging, but the underlying tension has been building for weeks.

In early June, leaders of the TUC, GMB, Unite, and Unison jointly declined Nigel Farage's invitation to affiliate with Reform UK—a collective rejection significant for a party positioning itself as a vehicle for working-class voters disappointed with Labour. That refusal cut off any institutional credibility Reform might have gained from labour movement backing before the motherhood proposals appeared.

The 12-month extension for filing claims is the most concrete part of the package. Under current Employment Tribunal rules, unfair dismissal claims must be lodged within three months of the action being challenged—a threshold that disproportionately affects pregnant workers and new mothers navigating dismissal, maternity leave, and a newborn at once. A 12-month window would align maternity claims with extended timelines seen in discrimination cases elsewhere, and it addresses a structural gap that employment lawyers and advocacy groups have flagged for years.

Where the package delivers less clarity is on everything else. Pledging to "protect existing maternity rights" commits to the status quo, not expansion. For an opposition party trying to build pro-worker credentials, that distinction carries weight. The TUC's 'deceptive' charge targets exactly this gap: the headline sounds broad, but the substance largely re-affirms what law already provides.

The political choreography is straightforward. Reform has been climbing in polls and is working to convert protest-vote momentum into a coalition that includes working-class women—a group that shifted substantially toward Labour in 2024 but remains politically contested. A 'Women and Motherhood Protection Act' signals an attempt to claim ground historically held by Labour and the union movement. The organised labour response—from the collective affiliation rebuff to the TUC's public condemnation—suggests unions view that encroachment as a genuine threat, not a hollow gesture.

The credibility problem for Reform is structural. UK maternity and employment law rests on statute, EU-derived rights retained after Brexit, and tribunal case law. A party without power cannot enact any of this; a party in government pursuing deregulatory labour policies faces an inherent contradiction. Unions have observed this pattern before: a party can champion specific rights in rhetoric while simultaneously pushing measures that weaken the enforcement tools, collective bargaining frameworks, and legal aid access that make those rights work in practice.

That tension will shape how employment lawyers, HR professionals, and union caseworkers—the practitioners who actually help workers navigate the system—receive this proposal. For them, a 12-month filing window for maternity claims is a genuine technical improvement if enacted. The surrounding political contest over who owns this cause is, for now, largely secondary to whether any of it becomes law.
