We have just arranged for our usual babysitter, that our DS loves, to pick him up once a week from school, bring him home, give him tea etc when he starts in September.
We only employ her irregularly at the moment and she has other jobs - she has another school run job (mornings) and some cleaning jobs as well. I doubt her hours add up to full time in any week, given she doesn't work many hours on the other school run job, and she doesn't do cleaning all day every day. As it's irregular we currently pay her cash but I think we will ask about monthly cheque/bank transfer for the school run job.
Do we need to do anything about her tax and NI, given that she has other job(s)? Or is that all up to her?
I've looked up the criteria for self-employment and she meets some of them (she has various clients, she could in an emergency get someone else to pick him up - though if she let us know she had to do that we'd probably just do it ourselves; but she can't decide to pick him up at a different time. If she decided to take him for a walk/to the park instead of straight home that would be fine and we wouldn't ask her to notify us in advance, her decision, but she has to start/finish her work at school/our house).
And if you have this kind of arrangement, do you have a contract?
