An employee is the starting point from which all degrees of relationship are calculated. Individuals are related by consanguinity if one is a descendant of the other, or if they share a common ancestor. An adopted child is considered to be the child of an adoptive parent for this purpose.  Individuals are related to each other by affinity if they are married to each other, or the spouse of one of the individuals is related by consanguinity to the other individual.

Approval must be obtained if the relationship is within the third degree by consanguinity (blood) or within the second degree by affinity (marriage). Refer to UPPS 04.04.07 Nepotism and Related Employment for more information.
