Part Year & Irregular Hours workers' holiday entitlement from April 2024

8 January 2024


What are Part-Year and Irregular workers and how is their holiday entitlement calculated?



What are the changes?


Regulations have been introduced to address the absence of a statutory method for calculating holiday entitlement for irregular hour and part year workers.


What's the relevant Legislation?


Employment Rights (Amendment, Revocation and Transitional Provision) Regulations 2023


When does it start?


For holiday periods from April 2024. Companies whose holiday period start in January 2024 need to wait until January 2025.


What is a Part Year Worker?


Someone is a part-year worker if they are contractually required to work only part of a particular holiday year and there are periods within that year (during the term of the contract) of at least a week that they are not required to work and for which they are not paid. This will include some term-time workers, for example.


Melanie, a seasonal worker in the farming industry who only works and gets paid during spring and summer months. Melanie would qualify as a part-year worker if her contract reflects that there are periods of time that last more than a week when she is not contracted to work and does not receive pay.


What is an irregular hour worker?


Kevin, a hospitality worker who works a different number of hours each week. Kevin would qualify as an irregular hours worker if his contract says that the hours he works will be wholly or mostly variable in each pay period. Kevin’s contract could be a ‘casual’ contract, otherwise known as a zero-hours contract.


When so you calculate from?


For holiday years beginning on or after 1 April 2024, holiday entitlement will accrue on the last day of each pay period at the rate of 12.07% of the number of hours that they have worked during that pay period, rounded up to the nearest hour. For example, if a monthly paid worker works 100 hours in a month, they will have accrued 12 hours of annual leave. Where the amount of annual leave that has accrued in a particular case includes a fraction of an hour, where the annual leave accrued is less than 30 minutes it will be treated as zero and it will be treated as one hour if it is 30 minutes or more.


Multiply the total hours worked by 12.07% to give the worker's total annual statutory holiday entitlement in hours.


How much can be accrued?


No more than 28 days, per year.

Employment experts foresee an increase in employment tribunal cases brought by employees as a result of employers requiring employees back into the office, full time. Those who try to avoid days in the office may be faced with their employers using entry-gate data to track staff attendance. The Telegraph reports that a number of companies are now advocating a full five-day return to the office, with others enforcing a minimum number of days in the workplace. Administrative staff at Boots, who previously worked in the office three days a week, will be required to return to the office five days per week from September. Earlier this year, an Employment Tribunal rejected the case of a senior manager who claimed against her employer, the Financial Conduct Authority, because she wanted to work at home full-time. Judge R Richter ruled that the FCA was within its rights to reject the employee's request stating that there are “weaknesses with remote working.....which will no doubt be the subject of continued litigation.” Is working from home so bad? According to KPMG’s 2023, CEO Outlook Survey ( Current trends in remote working (kpmg.com) , attracting and retaining talent is a top operational priority for CEOs to achieving their 3-year growth objectives and believe that remote working can play an important role in supporting talent retention and accessing new talent markets. There will no doubt be an increased number of claims brought against employers as remote working dissipates and employer's start to change the working dynamics.

Menopause symptoms can have a significant impact on women at work. Research by the Chartered Institute of Personnel and Development found that two thirds of working women between the ages of 40 and 60 with experience of menopausal symptoms said they have had a mostly negative impact on them at work. Of those who were negatively affected at work: 79% said they were less able to concentrate. 68% said they experienced more stress. nearly half (49%) said they felt less patient with clients and colleagues, and 46% felt less physically able to carry out work tasks. Baroness Kishwer Falkner, chair of the EHRC, said: “As Britain’s equality watchdog, we are concerned both by how many women report being forced out of a role due to their menopause-related symptoms and how many don’t feel safe enough to request the workplace adjustments."

The EAT has held that an employee’s redundancy dismissal was unfair where the employer failed to carry out meaningful workforce consultation at a formative stage. The respondent company carried out a scoring exercise using a standard set of subjective criteria. The claimant scored lowest in out of three in his pool. The respondent then met with the claimant three times before dismissing for redundancy. No consultation took place with the workforce prior to the scoring exercise. The EAT held that there was a clear absence of consultation at the formative stage, which meant there was no opportunity to discuss different approaches to any aspect of the employer’s redundancy process. The decision underlines the importance of appropriate workforce consultation, even where collective consultation obligations are not triggered. De Bank Haycocks v ADP RPO UK Ltd [2023] EAT 129
