Hi I hope someone can give me a little advice. I am in the process of setting up my own self employed swimming school, teaching children and adults of all ages to to swim. occasionally I may require swimming lesson helpers and qualified lifeguards to help me. I am not able to guarantee any hours as my requirements will be minimal as I am just starting out. I have trained contacts in the industry who are prepared to help me out for 4-5 hours a week if an when needed. However I am not sure what is the best way to pay these people as they would not ahve a contract. Please help me
