who collected my 3 kids from school 3 days per week at 3pm and was in my house til 5.30pm, (7.5 hrs perweek) am i still technically their employer and responsible for NI etc or can I just pay them their hourly rate? Sorry to seem a bit thick. Managed to work out how to advertise for someone but I'm not clear as to what mylegal responsibilities are for such few hours? I'd really appreciate any advice. I'm going back to work after a 9 yr career break and am finding my way. Thanks.
