I'm sure someone else will have said something similar but I've not got time to read the thread, but I wanted to explain something about carers on holiday as not just a carer, but also the parent of a special needs child.
Taking a service user on holiday is absolutely shite, even if you adore your client.
You have to be on hyper alert, you don't know how the changes in environment will affect your client.
You don't know the local area, you're also unable to relax at all, imagine if something happens and you have to attend a local hospital?
What if your client acts out and you've no back up from other staff?
What if they abscond/drink too much/get food poisoning?
What if something gets stolen, and the carer is immediately suspected?
Going on holiday as paid staff also means you're not paid an hourly rate, it's usually 10 hours a day and a sleep in rate.
You miss your family. Your home, pets, friends, you get absolutely no break.
Dependant on your service users needs, you may struggle to even use the bathroom for a week.
It's actually a really crap part of the job but carers do it because they want their service user to enjoy their lives and have meaningful experiences, they'd get more money just doing overtime to what they'd get on holiday.
To begrudge paying for them really isn't showering you in glory.
Bare minimum not only should all travel and transport be paid, also 3 meals a day.
Carers are usually working on NMW, they shouldn't be out of pocket when giving their time away from their families to be in a stressful environment or begrudged anything.
When my own DC will be wanting to have independent holidays with his carers, I'd be happy to pay for an additional carer to ensure that the staff are all given a day to enjoy some holiday each at least and take decent breaks throughout the day.
I find your attitude towards your DGSs carers extremely disrespectful.
