Nandidiri sila nung nalaman nila na nagwowork na ako sa BPO

Hi guys, just curious why people seems to look down upon a BPO employee? The context is, while waiting for my US deployment, naghanap muna ako ng work for a while, and i got landed in a healthcare BPO field (Im a doctorate in Physical therapy in US), nung nalaman ng mga kaibigan ng tatay at nanay ko and some of my college friends, they seem to feel unease, may comments pa na ''bakit ayan ang napili mo, may iba naman na work while waiting?'', '' bakit yan kinuha mo?'' . I dont get the hate on this job. May nagcomment pa na kaklase ko nung college sabe ''eww BPO life na ba yan"". Jeez.
