what you are referring to, is a cultural event, and not a professional one.
don't get me wrong:
this back-biting indeed, occurs amongst the females...new and experienced.
do not let anyone tell you differently.
recognizing the facetiousness that we are prone to, i have mostly had male friends all my life.
when i had my dtr, i raised her hoping she would grow up to be tolerant, respectful, assertive and open-minded.
(other desirable qualities, cannot be taught, ie, warmth, intelligence, integrity)
same with my boys:
i raised them all the same.
as teenagers, they're up to the normal pranks that come w/adolescence.
but as human beings, i couldn't be prouder.
they will all be aware of workplace b.s. and know how to deal with it, competently.
one step further, i profess they will all instinctively run to the underdog's defense.
this female phenomena is pervasive.
and i maintain, it's mostly about upbringing and what we as parents, can do to turn it around.
