Job control may include control over work tasks, control over the work pace and physical movement, control over the social and technical environment, and freedom from supervision. Workplace autonomy has been seen as a specialized form of the more general concept of control. Workplace autonomy is the freedom of a person to determine what he or she does at work, and how.
