oh goodness gracious, I know you dont fully understand AA/EO but do you not know how it works and what it does at all?
In the US AA refers to equal opportunity employment measures. This measures help prevent discriminating against employees on the basis of race, sex, creed, religion, color, or national origin. ALso five more recent statutes have listed other traits as "protected classes:
The Age Discrimination Act has protected those aged 40 and over
The Americans with Disabilities Act of 1990 protects individuals who possess, or are thought to possess, a wide range of disabilities, ranging from paraplegia to Down Syndrome to autism.
The Genetic Information Nondiscrimination Act of 2008 forbids discrimination on the basis of family history and genetic information.[5]
The Vietnam Era Veterans Readjustment Assistance Act of 1974 forbids discrimination on the grounds of a worker's military history, including any effects that the battlefield might have had on the worker's psyche.
Twelve states, over one hundred local governments, and the District of Columbia[6] have passed statutes that forbid discrimination on the basis of sexual orientation; also, the Employment Non-Discrimination Act would allegedly make sexuality a protected class, but this bill has yet to pass Congress.
