Discipline involves making people follow rules and correcting them when rules are broken. There are two types of discipline: organizational discipline, which is imposed by governing bodies, and self-discipline. Self-discipline is important for progress and involves controlling one's body and actions. In workplaces, discipline is necessary for employees to follow laws, rules and complete tasks, while organizations want obedience and conformity from employees. However, employees also want challenging roles allowing innovation. Maintaining discipline in organizations involves employment contracts, progressive disciplining systems, and investigations into issues.
