The concept of human rights empowers people and tells them that they deserve dignity from society, whether it's the government or their work environment. When they don't receive it, they can stand up.
Human rights ensures people have basic needs met, protects vulnerable groups from abuse, allows people to stand up to societal corruption, encourages freedom of speech and expression, gives people the freedom to practice their religion, encourages equal work opportunities, and generally provides a universal standard that holds governments accountable.
