A very good point you've made. I set pretty firm boundaries with my colleagues, clerical staff, and even my supervisor, but this is something I have not done much about because there is a backstory. Evidently, about two years ago, my department was struggling with "challenging" personalities and behaviors amongst the clinicians, peer support folks, and clerical staff, which escalated on several levels that ultimately led to most of the staff leaving and the supervisor being removed (or left on their own, I forget). Ether way, the few that remained were pretty bitter and jaded and they do not not want to feel like they are being condescended to, etc. by new clinicians, thus, they would prefer to be very relaxed in their professional demeanor with everybody, including our supervisor who is M.D./Ph.D. From what I was told by one of my colleagues, is that our supervisor initially introduced me by my first name to our clinic as to preemptively quell any potential bitterness/jadedness that may be evoked by the existing staff members - basically, to ensure they don't get "triggered" by my onboarding. In fact, I remember one of our peer support folks telling me "listen, you deal with veterans up there, and we deal with veterans on their level; you have to earn our respect."
I told my colleague I understand the "why," but I do not agree with it. I told my colleague that pandering to the rest of the group to appease them at my expense will only maintain their disdain towards others in "higher positions" (aka: doctors), and it makes me feel invalidated as a provider - someone who has literally earned the right and privilege to use the title "doctor." I don't go around treating people like crap, and I am very respectful and kind to my colleagues. I think that can be something we can do while also respecting professional titles and boundaries. By default, I will address my colleagues as "doctor" unless told otherwise, and I I will introduce my colleagues to patients and other staff members either by "doctor" or by "Mr./Ms." unless told otherwise.
IMO - we live in an era now where we are more vigilant about being mis-gendered and making sure others use our self-identified pronouns, but yet we can't address people as "doctor." It's frustrating.
So now, I basically acquiesce and give into their behaviors and all the while I stew in frustration. Not very healthy, but it is what it is for now.
