Recently I was told that I was not being hired because the MD wanted a female RN for "stand-bys"
Hey H60, there's no question that is discrimination. I'm an administrative resident in healthcare and I've spent significant time in Human Resources dealing with legal aspects. According to the Equal Employment Opportunity Commission (EEOC), when interviewing you cannot even ask questions that deal with gender, age, race, country of origin, etc., only questions that deal with specifically with the job (i.e. can you lift 30 lbs, can you work weekends). Obviously, discrimination happens, and if the MD wants a female, s/he is going to get one, but that office could get in a bunch of trouble if someone took the time to file a complaint. They shouldn't be admitting to looking for a female.
That said, I'm sure it sucks being 'hated' on like that:angryfire . Glad it worked out for you.
