There are two ways to write a nepotism provision. One is to have a
short, straightforward prohibition, and allow requests for a waiver
under special circumstances. The most frequent circumstance would be
a small town or school system where there are not a lot of prospective employees
to choose from.
The other way is the one chosen by Louisiana: three pages of
exceptions from the general rule (attached; see below).
There are two ways to define "family" in terms of a nepotism
provision: narrowly (parent, sibling, or child) or broadly.
Louisiana has chosen to define it somewhere in the middle.
