Hello, I need some advice when it comes to new clients. A bigger company has been in touch with me, asking if I would be interested in freelance work. I am currently freelancing for another company that is a direct competitor to the other company. I'm happy working for my existing client but obviously need to take on new clients too as I can't rely on just one source of income. Can a company demand that I tell them which other clients I am working for, if it is a direct competitor? Would appreciate your help on this matter! Thanks.
