I have just began searching for agencies in order to find day to day primary teacher supply work (London). After having read up on the best way to go about it, it is clear that being paid through an umbrella company is not ideal due to all the extra fees they charge. A google search only seems to show me many articles warning against umbrella companies but no advice how to avoid them other than to ask the agency. However, every agency I have contacted (8 so far) has insisted that they only pay through umbrella companies. Does anyone know of a teaching agency that will pay me directly. Do they even exist?
