A "obrigação" (duty) refers to a responsibility or task that an individual is required to perform. It can arise from legal, moral, or social expectations. For example, citizens have a duty to obey the law, while parents have a duty to care for their children. In professional settings, employees have obligations to their employers, such as completing assigned tasks and adhering to company policies. Fulfilling these duties is essential for maintaining trust and cooperation within society and workplaces. Understanding one's obligations helps promote accountability and ethical behavior.
