There are several monster species that have overcome the “monsters=bad” stereotype and have a generally good reputation in the mythical community and don’t have much problem finding work. Harpies are one of these species. Other humanoid species like gorgons tend to be feared, but can make it work. Non-humanoid monsters, on the other hand, generally have a hard time at it. There are a couple manticores living in the Liverpool Avalon who eke out an existence through busking/begging. In order to help their image, many manticores will amputate or otherwise make their deadly tails safe.
