Public service refers to activities and roles that aim to benefit the community and improve the quality of life for its members. This can include various sectors such as education, healthcare, and public safety, where individuals work to serve the needs of the public rather than for profit. Public servants, such as teachers, police officers, and healthcare workers, play crucial roles in maintaining societal functions. They often work for government agencies or non-profit organizations, focusing on delivering essential services and ensuring that the rights and needs of citizens are met.
