Not Sure About That.......?
I am not sure if you are right about that one 404. Federal laws have laws that prohibit discrimination on the basis of very specific criteria such as:
Race, Age, Gender, Religious belief and (excluding the military) sexual preference.
I do not have the time to hunt it up right now but there are some things that are quite legal to discriminate against and depending on relevant state and federal laws which naturally vary a little I think you may find that candidate selection based on marital status my well be discrimination but also legal.
I stand to be corrected, anyone else.............?
