And, let me presume, you want each and every employer to make up their own "internal grievance resolution mechanism", and that you wouldn't want those to be challenged either....right?
Because when an employer takes a negative action against you (demotes, re-assigns with lesser pay, fires), you should definitely work within their own invented "mechanisms" instead of seeking redress, because that seems "fair".
"I am firing you for being gay, now if you'd like to contest this, you must have sex with females for the next 30 days". Brilliant.
You're just babbling at this point. Go read Faragher v. City of Boca Raton and get back to me.
