First off, I'd like to mention that, for the most part, I found my coworkers (and clients) to be compassionate and lovely people. That being said:
Toxic work environment - Program Director is extremely unprofessional, and operates on a basis of blatant favoritism. She is overtly petty, and regularly insults and mocks staff members when they leave the room. Job outcome and experience is directly determined by whether or not she "likes" someone. This extends to her treatment of the residents, which directly influences the quality of their care.
genuinely meaningful experiences with clients
hostility, one-sided demands, toxicity "tickling down" from upper management
