Nepotism

ˈnɛpəˌtɪzəm

noun

the practice among those with power or influence of favoring relatives or friends, especially by giving them jobs

Nepotism comes from the Italian word 'nipote', meaning nephew. It refers to the favoritism shown to family members, usually in granting jobs or employment opportunities, rather than based on merit or qualification.

Is there one among you who dares cry “nepotism”?
