Nancy is a self-employed hairdresser. She runs a salon with the assistance of one untrained employee who takes bookings, tidies and sweeps up, and makes tea and coffee for the clients. Nancy would like to expand the business; this would involve employing a fully trained stylist. There is sufficient space in Nancy's existing premises for another person to work.
