How the UK Employment Rights Bill Changes Worker Rights

How the UK Employment Rights Bill Changes Worker Rights

The Employment Rights Bill 2024 is the most significant overhaul of UK employment law since the Employment Relations Act 1999. Introduced to Parliament in October 2024 by the Labour government, the Bill runs to over 150 clauses and addresses a broad range of labour market conditions: the rights of day-one employees, the terms on which zero-hours workers are engaged, the recognition rights of trade unions, and the protections available to workers in the platform economy. Its scale reflects both a deliberate political choice to make the reform the centrepiece of a new employment settlement, and a decade of accumulated concerns about insecurity in the UK labour market.

Whether the Bill's specific provisions deliver on that ambition is a contested empirical question. The Resolution Foundation's analysis of the Bill, published in November 2024, concluded that its provisions would reduce precarity for a significant share of the UK's 4.8 million workers on zero-hours or minimum-hours contracts, but that the net employment effect depended critically on how employers restructured their workforce in response. The Institute for Fiscal Studies raised questions about the likely behavioural responses of small employers to the day-one unfair dismissal provision. Those debates are worth understanding before the compliance deadline arrives.

Day-One Unfair Dismissal Rights Under the Employment Rights Bill

Under existing law, employees must complete 2 years of continuous employment before they can bring an unfair dismissal claim, with limited exceptions for automatically unfair reasons. The Employment Rights Bill reduces the qualifying period to zero, giving most workers the right not to be unfairly dismissed from their first day of employment.

This is the most contested provision in the Bill. Employer groups, led by the Confederation of British Industry and the Federation of Small Businesses, have argued that removing the qualifying period will make employers more cautious about new hires, particularly for small businesses without the legal resources to manage contested dismissal cases. The government's response, supported by evidence from the Resolution Foundation, is that most OECD countries with stronger day-one dismissal protections do not exhibit lower employment rates, and that the qualifying period has historically functioned as a window in which some employers dismiss workers shortly before the 2-year point to avoid liability.

The Bill includes a statutory probationary period framework that allows employers to follow a lighter-touch procedure for dismissals during a defined initial employment period, expected to be 9 months under the government's consultation documents. Critics argue that 9 months is shorter than the typical hiring and onboarding cycle for many skilled roles, making the effective protection weaker than the headline change implies.

Zero Hours Contracts Reform in UK Employment Law

The Employment Rights Bill's zero-hours provisions respond to a specific pattern identified by the Low Pay Commission and the Resolution Foundation: workers on zero-hours contracts often face systematic instability in their hours that prevents financial planning, access to credit, and stable housing, without receiving any of the compensating benefits, such as flexibility or premium pay, that justify the arrangement from a labour market perspective.

The Bill gives workers with unpredictable hours the right to request a contract that reflects their average hours over a reference period. It does not ban zero-hours contracts outright, a concession to sectors where genuine flexibility is operationally necessary, including hospitality, social care, and agriculture. It also requires employers to give reasonable notice of shift changes and to compensate workers for late cancellations.

For employers relying heavily on flexible staffing, the practical effect is a significant increase in administrative burden and a new category of employment tribunal risk. Compliance requires employers to track average hours over reference periods, establish formal processes for handling requests for predictable contracts, and document the business reasons for any refusals. The ACAS code of practice on zero-hours contract requests, expected to accompany the Bill's implementation, will be the primary practical guidance document.

Trade Union and Collective Bargaining Reform

The Employment Rights Bill includes a substantial package of trade union reforms that reverse several provisions of the Trade Union Act 2016 and the Conduct of Employment Agencies and Employment Businesses (Amendment) Regulations 2022. The minimum support thresholds for industrial action ballots are being lowered. The requirement for a 10-day notice period before strike action is being reduced. The ban on employment agencies supplying workers to fill strike-affected roles is being reinstated.

These provisions are explicitly political as well as economic. The government's stated rationale is that the 2016 Act's restrictions on industrial action have suppressed legitimate collective bargaining and contributed to the wage stagnation that the Office for National Statistics has documented across much of the UK service sector. The Resolution Foundation's pre-distribution index, published in 2024, found that the UK's collective bargaining coverage had fallen to approximately 23% of the workforce, the second lowest in the OECD after the United States.

The business community's concern is that reinstating broader strike powers during a period of wage pressure and supply chain fragility creates operational risk for businesses in sectors with strong union presence, including the public sector, logistics, healthcare support services, and energy.

What Employers Need to Prepare for Under the Employment Rights Bill

Regardless of where any given employer stands on the policy arguments, the Employment Rights Bill creates specific compliance obligations with defined implementation timescales. The day-one unfair dismissal right requires a review of probationary period policies, documentation standards, and management training for early-stage dismissal procedures. The zero-hours provisions require an audit of flexible staffing arrangements and the development of processes for handling requests for predictable contracts.

The Bill also creates obligations in areas beyond the headline provisions. Enhanced protections for pregnant employees and new parents, mandatory equality action plans for large employers, and a new duty to take 'reasonable steps' to prevent sexual harassment, rather than merely to respond to it, each create distinct compliance programmes that HR and legal teams need to begin building now. The Equality and Human Rights Commission is expected to publish updated guidance on the sexual harassment provisions once the Bill completes its parliamentary passage.

The Employment Rights Bill is not a simple recalibration of existing rules. It is a structural reset of the bargain between employers and workers in the UK labour market, with provisions that interact with each other and with existing law in ways that will require specialist interpretation. The Employment Tribunals system, already under significant pressure from case backlogs documented by the Ministry of Justice in 2024, is the enforcement mechanism for most of the Bill's provisions.

Fun fact: The Employment Rights Bill 2024, at over 150 pages and 170 clauses, is one of the longest pieces of employment legislation in UK history. The last comparably broad employment law reform was the Employment Relations Act 1999, which introduced new rights on union recognition and parental leave in the early years of the Blair government.

The Bigger Picture of UK Employment Law Changes

The Employment Rights Bill is best understood alongside the wider package of UK labour market policy in 2025 and 2026, which includes the National Living Wage increases confirmed by the Low Pay Commission, the planned review of the apprenticeship levy, and the ongoing expansion of the national minimum wage to 18-to-20-year-olds. Together, these reforms represent the most active use of labour market legislation by a UK government since the 1990s. Whether the macroeconomic effect is net positive, through higher wages and reduced precarity, or net negative, through employment caution and reduced hours for some workers, will be a core debate for the OBR, the Resolution Foundation, and the IFS over the next 3 to 5 years.
