Corporate bullying is also rampant especially in the BPO industry. I was the bullied before but I transformed that energy and negative criticism to better my performance. Sometimes, it is also the substance of the bullied not the circumstance.
They should learn to stand up to the bully and prove him/her wrong. We are born with different intelligences so the bully might excel in one aspect but is weak in the other. If it is the worse kind of bullying though, it would be better to report the incidents.
