Do agents and managers work together?
Yes. But it depends on the project. For commercial work because the agent has many more clients on their roster, the casting director will call them because the agent has a wider selection of children to choose from. That is why a manager will introduce them to commercial agents and forge working relationships with agents. There should be only ONE manager. A manager is at the top of totem pole. He/She ensures that the child has as many working relations with commercial agents as possible to ensure that the child is considered for whatever projects come along.
