A friend has a small care agency. Her accountant has advised her to make all her staff self employed and that she needs to send them all a letter telling them that as they decide each week what hours they will work, then rotas are drawn up, that they are casual staff who are self employed. They are therefore responsible for paying their own NI and tax. Have you any advice how this should be worded or what the staff should be told?

I have only ever come across this in IT with contractors

Thanks
