Anyone who's worked in care with 'sleep-ins' where you're paid a flat rate rather than an hourly rate - has your holiday pay ever reflected the sleep-ins, or is it fine for employers to disregard this? I have asked ACAS and the advisor I spoke to wasn't sure about the law - but in practice, is including sleep-ins in holiday pay a thing? In support work doing 'sleeps' can increase your gross pay by literally hundreds a week, so if you take a holiday you'll have much less money coming in if the pay doesn't take into account sleep-ins.
