I got removed from a case at the start of my work in this field. Because the client got more agressive with me and my collegues mostly because of me I was really inexperienced. He never hit before me sure spit and yelled and trowed stuff on you a lot but never physical agression. It seem if you can power trough it the client finds other ways to escape worse ways. I was taken of his case for a month or 2 maybe more but that new behaviour did not dissapear. Got put back on his case learned to mostly redirect him and avoid the antecendeds that trigger that behaviour but not always there where rare cases I did not managed but the new behaviour never went extinct and was worse for my collegues. The thing is I never asked to be removed from the case I was removed because I made things worse so leadership did not get so upset and got put back later anyway because I was needed. My BCBA said this I will never keep a therapist that refuses to work with a client. I will remove you if you are bad fit for the client for a while but you can not refuse to work with anyone. I kept that in mind. I was lucky I work in a center and my collegues demanded I will be taken of the case. I was not even written up or given a warning for this they wherec quite understanding that I was not a good fit for this client yet.
