On 10 October 2024, the Government published the Employment Rights Bill (ERB) 2024-2025 , promised within the first 100 days of the new Parliament with reforms including measures on ‘exploitative’ zero-hours contracts and ‘fire and rehire’ practices, and establishing protection from unfair dismissal, as well as entitlement to sick pay and parental leave rights from day one of employment
The ERB completed the initial House of Commons stage and on 14 March and now before the House of Lords (stage 2). Detailed scrutinisation of the Bill by a Committee of the Lords began on 29 April 2025.
When introduced in the House of Commons in October 2024 the ERB was 158 pages long. Following numerous amendments from the House of Commons stage, by March the ERB has approximately doubled in size to 310 pages! The ERB as brought from the House of Commons (version 3) is one of the largest single pieces of purely new employment legislation ever introduced with 157 clauses and 12 schedules (while the Equality Act 2010 was larger with 218 clauses and 28 schedules the majority of the provisions were consolidating existing provisions). One thing for sure, is that extensive employment law changes are on their way!
Many of the March amendments are simply technical amendments to ensure that the provisions of the ERB actually do what is intended. However, some are more significant such as a watering down of the changes in relation to collective redundancy consultation thresholds - the 'at one establishment' has been saved, though a modified threshold will apply in some cases (detail awaited). We also have some very significant whole new provisions, such as the increase in the time limits for bringing an employment tribunal claim from three to six months and an extension of the zero ours/low hours guaranteed hours contract provisions to agency workers.
And more to come on 29 April the Government put forward 27 more amendments at the first sitting of the House of Lords Committee stage in relation to the guaranteed working hours provisions (see below).
The significance of the ERB should not be underestimated.
Issues of debate before the House of Lords include:
In November 2024, the Government published the 'Next Steps to Make Work Pay', outlining the time frame for the reforms set out in the Bill, as well as detailing additional reforms it will look to implement in the future, including:
On 18 March a consultation on the proposed mandatory ethnicity and disability pay gap reporting provisions to be included in the Equality (Race and Disability) Bill was published. We also have an update on other measures outside the ERB, such as the shelving of the proposed 'right to switch off' Code of Practice.

Before turning to the 'what?', we start with the 'when?'. The Bill itself is expected to be passed before the summer recess. However, as set out in the 'Next Steps to Make Work Pay', much of the detail on many of the policies in the Bill will be provided through implementing regulations, and in some cases codes of practice, which will need further consultation. The Government expects to begin consulting on these reforms in 2025. As for coming into force, a small number of the changes relating to trade union law reform, are to come into force two months after the Bill is passed. However, the majority of the changes will not be brought into force before 2026 with the changes to unfair dismissal qualifying periods not before autumn 2026
Policy
A ban on 'exploitative' zero-hour contracts ensuring workers have a right to a contract that reflects the number of hours they regularly work. The policy also includes giving workers "reasonable notice" of any shift changes and compensation for any cancelled or curtailed shifts.
Following consultation, the Government has amended the ERB to extend the rights in the ERB to guaranteed hours contracts, reasonable notice of shifts and compensation for short notice of cancelled, curtailed or moved shifts to agency workers (see Agency Workers below),
The Bill's provisions (zero-hour/low hour contracts)
The Bill when passed will insert new sections 27BA to 27BT into the Employment Rights Act 1996, resulting in complex provisions.
1. Right for qualifying workers to be offered guaranteed hours
Employers will be required to offer a guaranteed hours contract (GHC) to 'zero-hour' or 'low-hours' workers after the end of every reference period. Essentially, the new right will apply to a 'zero' or 'low' hours worker who, during a relevant reference period, worked a number of hours that satisfy certain conditions in respect of number, regularity or otherwise.
This right will apply to those employed by the same employer under one or more worker's contracts (whether or not continuously) in the relevant period.
For qualifying workers
Important detail being is left to implementing regulations includes:
2. Right to reasonable notice of a shift
The ERB also provides for employers to provide workers with reasonable notice of when they require them to work and also reasonable notice if they need to cancel, change or rearrange a shift. This will apply:
What is 'reasonable' will depend on all the circumstances of a case. It is to be presumed, unless the contrary is shown, that notice of a shift will not be reasonable notice if it is given less than a specified amount of time (to be set out in subsequent implementing regulations) before the shift is due to start.
3. Right to reasonable notice of cancellation of or change to a shift
Employers must give workers reasonable notice if they cancel a shift or change the day or time.
It is to be presumed, unless the contrary is shown, that notice will not be reasonable notice if it is given less than a specified amount of time (to be set out in subsequent implementing regulations) before the shift would have started or on or after the start of the shift.
4. Right to payment for cancelled, moved and curtailed shifts
Employers will be under a duty to make a payment, of an amount to be specified in subsequent implementing regulations to a worker each time there is a cancellation, movement (i.e., a delay or bringing forward of a shift), or curtailment at short notice of a qualifying shift that the worker has agreed to work for the employer.
Curtailment of shifts can include hours being cut from the middle of a shift (in addition to the start and finish). The maximum amount of compensation for cancelled, moved and curtailed shifts is the amount that would have been earned save for the cancellation or curtailment and if moved what they would have earned for the original shift with such payments to be treated as 'wages'.
Important detail being left to implementing regulations includes:
5. Agency workers guaranteed hours and rights relating to shifts
Amendments to the Bill extend protection to agency workers intended to "ensure that agency work does not become a loophole in the plans to end exploitative zero hours contracts". See "Agency Workers" below.
6. Collective agreements contacting out
Following an amendment to the ERB, the rights to guaranteed hours, reasonable notice of shifts and compensation for cancelled, curtailed or moved shifts for zero hours, low hours and agency workers (see below) can be excluded by a relevant collective agreement. A relevant collective agreement is one which is in writing and made by, or on behalf of, one or more independent trade unions and the worker's employer. Contracting out on this basis can occur where the relevant terms of the collective agreement are incorporated into the contract, provided that the worker or agency worker has been notified in writing of the incorporation and effect of those terms.
This is a key change inserted into the ERB in March 2025 as it:
This potential option appears to be a pragmatic approach to address employers' concerns about the workability of these provisions but will require agreement with the relevant union. Allowing an employer and trade union to reach agreement on arrangements, will simplify compliance with the complex new provisions where agreement can be reached.
Under the current version of the ERB, this is the only basis upon which it would be possible to contract out of these provisions. Accordingly, there is no opt-out route for non-unionised workplaces.
7. Anti-avoidance measures
A new provision has been added to the ERB to prevent the manipulation of hours made available to a worker, with the intention of making a lower guaranteed hours offer, or to avoid the obligation altogether.
The amendment introduces the right to bring a claim in the employment tribunal in respect of a guaranteed hours offer made by the employer on terms requiring the employer to provide, and the worker to do, less work than would have been the case if the employer had not, for the sole or main purpose of being able to comply with the duty by making such a reduced offer, during the relevant reference period:
The employment tribunal may make a declaration and an award of compensation up to the "permitted maximum", which will be specified in regulations. There are equivalent rights for agency workers which can be brought against the hirer or work-finding agency, depending upon which party has limited the hours worked during the relevant reference period.
8. Existing predictable terms legislation
The ERB will repeal the existing Workers (Predictable Terms and Conditions) Act 2023.
Comment
The above provisions are intended to end one-sided flexibility, ensuring that jobs provide a baseline of financial security and contractual predictability so workers can better plan their lives and finances. We await the consultation on important elements such as what constitutes 'low hours' contracts and what will be the requirements of a 'guaranteed hours offer', the Government has stated it will also ensure that
The 'who' question - guaranteed hours
Just where the threshold will be set for those considered to be working on a 'low-hours' contracts will significantly shape the impact of the guaranteed hours contract provisions. If a low threshold is set, for example at two hours per week (as some Conservative MPs argue), then many employers would simply guarantee workers two hours of work. If the threshold were to be set at 16 hours per week (as others argue), then the provisions will have much greater impact. Many part-time workers would be in scope and employers would have to monitor any additional hours they worked very carefully.
The 'who' question - shift notification
The need to offer a guaranteed hours contract will apply in relation to 'zero-hour' or (yet to be defined) 'low-hours' workers. However, the rights to shift notification/cancelations/curtailment and the corresponding compensation provisions apply to zero-hour workers and to workers who work under a contract 'of a specified description' requiring them to be provided with some work but without specifying the times or pattern of days and times of that work. We do not currently know what "of a specified description" will mean, but it appears that is not limited to the yet to be defined 'low-hours' workers. As such this may be wider.
The 'reasonable notice' of shifts question
What 'reasonable notice' of shifts is going to be is currently unknown. A presumption will operate that unless the contrary is shown, notice is not reasonable unless it is of the specified length, which has not yet been defined. Clearly, the longer the notice that is required, the greater challenges that employers will face with the shift notification provisions. Likewise, it is unknown what factors will be relevant to rebut the presumption. The factors that a tribunal must have regard to when determining whether reasonable notice was given are to be set out in regulations but again are as yet unknown.
Another potential issue arises where an employer puts out a call to workers seeking shift cover. As currently drafted a worker is entitled to reasonable notice of cancellation where the employer has requested the worker to work a shift and they have agreed. This could include a scenario where the employer puts out a call to multiple workers to work a shift but only some of them are required. If, for example, the employer states that the first three to respond will be given the shift, will the reference to the first three to respond be sufficient to amount to a 'cancellation of the shift'. Will the employer need to expressly comply with the cancellation requirements for any volunteers after the first three?
The 'reference period' question
What the reference period will be, is also an important issue for consultation. While the Bill is silent on the definition of the 'reference period', in the "Next Steps to Make Work Pay" the Government favours a 12-week rolling reference period. The Bill states the initial reference period will be the period between the day when the worker is employed and "the specified day", for example the day at the end of 12 weeks as favoured by the Government. Subsequent reference period means "a period beginning and ending with the specified days". But note the use of the phrase "rolling reference period" differs from that used for calculating holiday pay for some irregular hours workers, but rather, there will be an initial reference period and then subsequent reference periods will start at the end of the initial period, with further reference periods only commencing after the end of the previous reference period adding to the administrative complexity.
While we await confirmation as to what the 'reference period' will be (likely 12 weeks), on 29 April 2025 the Government added an amendment to provide a method for the calculation of guaranteed hours for workers on annualised contracts. This is to ensure that workers on such contracts or other contracts where hours are guaranteed over a period longer than the yet to be defined 'reference period' are within scope of the right to guaranteed hours.
The hot topic reference period question is how to account to for seasonal variations in workloads? This will be an important part for the future consultation. It should be remembered that zero-hours contracts are not being banned altogether. While employers will be required to make a 'guaranteed hours offer', it can be for a limited term where reasonable. Having said that, the employer will need to rebut the presumption that it is not for a limited term. Will significant seasonal variation be sufficient to rebut the presumption?
In the response to the consultation on the application of zero hours contracts measures to agency worker, the Government recognised concerns regarding seasonal or temporary work. It recognises that it would be inappropriate to require hirers to provide qualifying zero-hour contract and agency workers in genuinely temporary work with a permanent contact. As such it intends to consult before setting out further detail about what constitutes a temporary need in future regulations. It is also keen to discuss other ways in which the legislation could cater for seasonal work.
Worker's choice only
The worker will not be obliged to accept the offer, thereby retaining full flexibility on the worker's part. The Government states that it appreciates that zero-hours contracts can work well for some individuals, such as students and those with caring responsibilities, so those who are offered guaranteed hours will be able to remain on zero-hours contracts should they wish. As for the employer, the duty to make an offer of guaranteed hours will keep applying until the worker no longer satisfies the definition of a qualifying worker, which will only be when their contract guarantees more than a minimum number of hours to be specified in regulations (in other words, when they are no longer considered to be working under a zero-hours or low-hours contract). There are equivalent provisions for qualifying agency workers.
As currently drafted these provision place on employers a rolling need to offer a GHC to workers including those who have confirmed they do not want a GHC, instead wishing to retain their existing flexible arrangement. This appears to be unnecessary bureaucracy. One obvious solution would be to provide an opt-out option similar the 48-hour working week opt-out which can last indefinitely subject cancelation by the worker at any time by serving seven days' notice. We wait to see if the Government will consider any such opt-out, beyond the collective agreement with a trade union route (see above).
Next steps
The one thing that is sure, is that the legislative provisions are extremely complex. How workable these provisions will be will largely depend on future consultations and the detailed implementing regulations. The definitions of "low hours" workers and the "relevant reference" will be crucial as will the promised future consultation on what will constitute a "temporary need"/"limiting event" exempting the need to offer a guaranteed hours contract.
These provisions are not expected to come into force "earlier than 2026". Given the need for future consultation and extensive and significant substantive regulations with further consultation, 2026 may prove to be optimistic.
The Neonatal Care (Leave and Pay) Act 2023 provides for a statutory right to up to 12 weeks paid neonatal care leave for eligible employed parents whose new-born baby is admitted to neonatal care. This is in addition to other leave entitlements such as maternity and paternity leave. The 2023 Act is largely an enabling Act, with much of the detail of the rights left to further regulations.
On 20 January 2025, the Government published the draft substantive implementing regulations to come into force on 6 April 2025: The Neonatal Care Leave and Miscellaneous Amendments Regulations 2025 and The Statutory Neonatal Care Pay (General) Regulations 2025. Subsequently, the Statutory Neonatal Care Pay (Administration) Regulations 2025 were also published.
Neonatal Care Leave will apply:
Neonatal Care Leave Pay
The statutory Code of Practice on Dismissal and Re-engagement devised under the previous Conservative Government came into force on 18 July 2024. The new Code sets out how employers should act when:
Employers are expected to consult employees and explore alternative options, without raising the prospect of dismissal unreasonably early or using the threat of dismissal as a negotiating tactic to put undue pressure on employees.
Notably, the Code states that "the employer should contact Acas for advice before raising the prospect of dismissal and re-engagement". Failure to follow the Code could result in a 25% uplift to compensation awards in relevant cases including unfair dismissal and discrimination. A notable omission from the list of clams to which a 25% uplift can apply are protective awards for failure to collectively consult on collective redundancies. The pre-election proposed addition of protective awards unfortunately failed to gain House of Lords' approval before the general election.
On 2 December 2024, a new The Trade Union and Labour Relations (Consolidation) Act 1992 (Amendment of Schedule A2) Order 2024 was made providing for the 25% uplift to apply to protective awards for failure to collectively consult on collective redundancies from 20 January 2025. As transitional provisions have not been included, an uplift or reduction could potentially apply in any pending claims to which the Code applies, not just new claims brought since 20 January 2025. (Note: the Code does not apply where the prospect of fire and re-hire was raised with employees or their representatives before 18 July 2024.)
See above for future reform under the Employment Rights Bill to further strengthen the Code.

The 'Next Steps to Make Work Pay' confirms this Bill will:
Next steps - consultation
On 18 March 2025, the Government commenced a consultation seeks views on how to implement mandatory ethnicity and disability pay gap reporting for large employers in Great Britain for employers with 250 or more employees: Equality (Race and Disability) Bill: mandatory ethnicity and disability pay gap reporting. The consultation closes on 10 June 2025.
A separate call for evidence will be published at a later date to seek views on other parts of the Bill, including making the right to equal pay effective for ethnic minorities and disabled people.
The consultation states that the Government’s aim is to use a similar reporting framework for ethnicity and disability to that already in place for gender pay gap reporting, which was introduced for large employers in 2017. It proposes to:
The Equality and Human Rights Commission will be responsible for enforcing the new pay gap reporting requirements.
In contrast to gender pay gap reporting, employees would be asked to self-report their ethnicity and disability status, with an option to opt out. The Government proposes using standardised ethnicity groupings. Given data protection considerations, it proposes a minimum of ten employees in any ethnic group being analysed. Smaller groups may need to be aggregated. It is proposed that all employers should report, at a minimum, a binary comparison, preferably between White British employees and all other ethnic minority groups combined.
Similarly, with disability reporting, a minimum of ten employees must fall in each group being compared. To avoid the risk of individual identification and the complexities of multiple impairments, the Government proposes that disability reporting should take a binary approach of only reporting differences between disabled and non-disabled employees, rather than by type of impairment.
Comment
As regards pay gap reporting, finding a methodology resulting in meaningful data is no easy task. The proposed approach set out in the consultation attempts to address difficulties that arise due to small statistical group issues and issues around classification of those of differing ethnicities/disabilities, but does this leave any meaningful data? How comparisons for identifying pay gaps across a wide range of race-based identities and very different forms of disability is challenging.
We expect there to be more changes coming for employment law in the next few months as the new governmental policies and legislation take shape.
