Working ad-hoc - holiday pay

[juneybean]

I am intending to lower my hours to ad hoc in a few months and the whole situation with my employers has been handled completely haphazardly and I was just hoping to get some advice.

If I work as and when required, whether this is 1 hour one week and 20 the next, what holiday entitlement should I be due and how should this be worked out?

For the record, I am paid an hourly rate on a monthly basis :D

Thanks to anyone who can help!

Normally one hour for every 13 hrs worked equates to 4 weeks leave

not an expert but I think your holiday pay would normally be worked from your contracted hours so if you have a nil hours contract ie they can't make you work any hours if you don't want to, then you would not be entitled to paid holiday. if you have an agreement to work x amount of hours per week/ month /year then your holiday entitlement would be pro rata to that.
Try the ACAS website.

juneybean you should accrue holiday literally as hours are worked. Entitlement is 4.8 weeks now, which is 10.2% of time worked, so you should accrue paid holiday time at the rate of 10.2% of the hours you work. Or just over 6 minutes accrued time off for each hour you work.

Does your employer not have anyone else on a zero hours or flexible hours contract?

I agree with what Flowery said....

I've worked in places where we've agreed with individuals that they'd be paid an enhancement for annual leave, where they are flexible contracts.

Oh, and just to add to what I said, statutory entitlement is 4.8 weeks and the calculation is on that basis, but if your employer usually pays more than the basic holiday entitlement, you should get the same as anyone else on a pro rata basis worked out in a similar way.

I agree with heavy that acas would be a good place to look, or else maybe if you are in a union they would be able to help if your employers are being awkward (or even just uncertain of the rules)?
If it helps me & dh run a (very small) business and often have people to help us for a few weeks and with varying hours per week. We just work out how long they've worked at the end, and pay holiday pay pro rata for that, minus any days off in the meantime.
I think that even casual (zero hour contract) and piece work workers are entitled to holiday pay now legally (and if they aren't then they ought to be IMO!)
