Sometime you worked in a place few key people pretending running it you are not fit, the truth hurts because I did all my best and a sign being promotable it seems not for them caused jealousy and bad mouths to management liked you don't belong there, in light sometime hard experience pays off for a better opportunity to make someone liked you or me did the best, what matters not what other negative peer in the work place think, mind and your quality & personality will be the same, just find the right place and people to share deservingly no matter what because we are naturally the best and does not changed!
