Unions worry Labour’s plan for zero-hours contracts may break manifesto pledge

Zero-Hours Reform Faces Implementation Crisis as Unions Challenge Labour’s Narrowed Scope

Wanderstayfinder.com – The gap between what Labour promised voters in its manifesto and what its own consultation document appears to deliver has become the sharpest fault line in the government’s employment agenda. Trades unions have formally pressed Business Secretary Jonathan Reynolds to explain why the forthcoming guaranteed-hours contracts — the centrepiece of Labour’s plan to dismantle exploitative zero-hours arrangements — may exclude large swathes of the workforce the original pledge was meant to protect. With the consultation window closing within days, the dispute over eligibility thresholds and enforcement mechanics has moved from backroom policy debate to open political confrontation.

The Threshold Problem

At the heart of the union alarm sits a single mechanism: an upper hours threshold embedded in the consultation document. Under the proposal, workers whose existing contracts already guarantee them more than a set number of hours per week — a figure the document floats anywhere between eight and forty-eight — would be rendered ineligible for the new right to a contract matching the hours they actually work. In practical terms, this could strip the protection from part-time and even some full-time employees who, despite holding nominal guarantees, still face unpredictable scheduling and last-minute shift cancellations.

Joanne Thomas, general secretary of the shop workers’ union Usdaw, framed the issue in blunt terms:

“The right to a contract that guarantees the hours you normally work is a matter of basic fairness and security. It must be applied to everyone to deliver the government’s manifesto commitment.”

She pressed further, insisting the measure “must apply to everyone up to and including full-time workers” and warning that any carve-out would render the reform “meaningless.”

Unite’s Regularity Challenge

A second, distinct objection came from Unite, which flagged what it called a “regularity requirement” — a condition suggested by the government that would, in the union’s reading, bar a substantial cohort of workers from qualifying altogether. The union’s spokesperson was scathing:

“If the government was attempting to create a right which virtually no workers could qualify for or be able to enforce – they could not have done a better job.”

Ross Holden, head of policy and research at the GMB union, echoed the broader unease, cautioning that “without a major rethink there is a risk this policy is not matching what we said in the manifesto.” He added that unions fear their objections are not being weighted adequately in the ongoing deliberations, warning that “if the policy development is one-sided then we risk this being watered down.”

Business Pushback and the £2.9bn Question

The government’s own cost modelling, released last week, has given employers a focal point for opposition. The most expansive variant of the guaranteed-hours scheme could impose annual costs of up to £2.9 billion on companies. The British Chambers of Commerce described the prospect as “a further hammer blow for many firms struggling to keep their heads above water.”

Kate Bell, assistant general secretary of the Trades Union Congress, pushed back on the framing. She noted that forty per cent of that upper-bound figure represents compensation employers would owe for cancelling shifts at short notice — a cost that, in her assessment, “assumes no behavioural change by employers” and presumes they lack “the creativity and the experience to adapt their model.” The same government document, Bell pointed out, found that irregular and unpredictable shifts cost roughly one in three workers on zero-hours contracts around £3,000 per year in lost earnings and instability.

“We keep having to have the same argument time and time again about the real costs of insecurity for workers,” Bell said. “Most people don’t want to be on these contracts. They’ve been on these contracts for a long time and it has costs for their mental health and their financial security.”

The TUC separately condemned what it characterised as “scaremongering” from business groups, arguing that the cost figures were being deployed to manufacture doubt about a reform the government had already committed to in statute.

Political Context: A New Secretary, Old Debates

The timing sharpens the stakes. Jonathan Reynolds returned to the business secretary’s portfolio during Andy Burnham’s wholesale cabinet reshuffle last month, after having been displaced from the post by Keir Starmer earlier in the parliamentary cycle. The zero-hours consultation closing next week makes the issue one of the first substantive files on his desk. Reynolds now faces the task of reconciling union demands for universal coverage with employer resistance to cost exposure, all while the Employment Rights Act — which has already received royal assent — awaits its implementing regulations.

The Act itself is law, but the zero-hours provisions are not scheduled for implementation until next year, leaving a wide window in which eligibility criteria, enforcement mechanisms, and transition arrangements remain negotiable. That window is precisely where the current fight is taking place.

Government Position

A spokesperson for the government reaffirmed the commitment: “We are absolutely committed to ending exploitative zero-hours contracts, where workers bear all the financial risk when hours, shifts and earnings are unpredictable. These reforms will give workers in every postcode greater income security and predictability of hours.”

The spokesperson added: “While no final decisions have been made, we’re consulting with business and trade unions including GMB, Unite and Usdaw, to get the detail right and ensure this works in the real world.”

Why It Matters

Zero-hours contracts — arrangements in which employers offer no guaranteed minimum hours and workers must accept shifts as they arise — have been a defining feature of Britain’s labour market since their proliferation accelerated after the 2008 financial crisis. They concentrate scheduling risk entirely on the worker: no income floor, no advance notice, and in many cases no recourse when shifts are withdrawn at the last minute. Labour’s manifesto pledged to eliminate the “exploitative” variant of these contracts, and the Employment Rights Act codified that ambition into statute. What remains contested is not whether the reform will happen, but how broadly it will bite. If the final rules exclude the majority of workers currently trapped in unpredictable scheduling, the political and industrial-relations consequences will extend well beyond the next election cycle.
