Not for the first or last time, I both agree & disagree with Cyndy.
The starting point is that there is an
ECJ judgment that says rolled-up holiday pay is not allowed. Member states were required to take measures to ensure such practices were not continued. (To date (10 years after the judgment), the UK government has not made any relevant amendments to the law; I think there might have been consultations, but no changes to the law.)
But there are two issues that need to be considered when acknowledging that rolled-up holiday pay is not permissible:
1. The ECJ judgment effectively said employers shouldn’t use rolled-up holiday pay, but could if they make it clear they are on a payslip.
(Given the wider judgment, this is not recommended for most contracts – I’d certainly agree with Cyndy in this regard.)
2. (Genuine) Zero-hour contracts are stand-alone contracts: they can be extremely short in their nature, and therefore the contract would end within a week or so – or whenever the terms of the hours offered, accepted, & worked are completed. If a new period of work is offered & accepted, a new contract term is entered.
(Most “zero-hours” contracts are not that at all, they simply have fluctuating weekly hours; I believe I heard a politician today mention this was an average of 20 hours (no idea where the stats to support this are from). But the employment relationship in these instances, whether as worker or employee, has a continuation, there is no break in the contractual relationship – and genuinely, these are (certainly arguably) not “zero-hours” contracts.
If an employer offers to a casual worker they know & have worked with before some hours, and those hours (or even some of them) are accepted, that’s a zero-hours contract, and when the agreed hours are done, the contract is terminated. Holiday pay is still due, so no other option but to roll this up – it has to be paid on
termination of the contract.)
For the reasons above, I would suggest the OP get professional advice on drafting the terms. And White Collar Legal does too, if they are using these terms for “staff” rather than genuinely casual workers – someone you might call upon from time-to-time, on zero-hours terms.
