The broad aims of this study are to gain insight into employees' on-the-job learning activities to help them improve their on-the-job learning. The authors define on-the-job learning styles and operationalize the concept to include both mental and overt learning styles and both interpersonal and intrapersonal learning styles. Organizations and employees can benefit from an awareness of employees' on-the-job learning styles, by developing an adaptive flexibility in the use of on-the-job learning strategies.
