My question involves labor and employment law for the state of: Federal.
1. Why does ADEA require at least 20 employees while most other similar major laws require at least 15? Is it arbitrary or is there a rationale?
2. Is I-9 not needed if one has only 3 employees? So it is OK to employ a couple of individuals unauthorized to work in the US?
As mentioned, my interests are academic in nature. The questions were raised in class by my students.
Thanks in advance,
