you have bewitched me, body and soul

The hierarchical structure in these environments is to create a chain of command. The higher the individual is in the chain, the more responsibilities and liability they gain.

Robby in Season 1 is considered to be the chief of the department; by Season 2, Robby is indicated to have received an official title as chair (S2e8). Robby is in two of the highest positions on the department floor. His position is above everyone else in the structured working hierarchy. Everything then should go through him, as he would be the one who directly coordinates with upper management.

In S2E7-E8, it makes sense to discuss with Al-Hashimi as she has training in the area, but Norris intentionally removes Robby from his hierarchical roles in the department.

Upon arrival, Norris calls Robby a playcating, almost mockingly kind, nickname to ease into conversation ("Rockstar"). Robby asks if it's something he needs to know before they announce it to everyone. Norris replies "no".

Not only did upper management fail to forewarn the ED so they could get everything in order, thus supporting everyone in that department and the patients, but when asked why it wasn't also discussed with Robby, who is directly in charge of the floor, Norris replies that he consulted with Al-Hashimi, his "fellow attending".

Norris intentionally removes Robby from two higher up positions he holds, verbally to his face and in front of the ED that has been called together. It also places Al-Hashimi in an awkward position, as she is used to disrespect a fellow employee.

Whether you agree with the job structure, or with him holding the highest positions or if you think he's right or wrong doesn't really matter. It...just is.

But I dunno about anyone else but it is not uncommon in care fields refer to their work with possession. "My Work" "My Class" "My School" "My practice" etc.

For Robby his identity is so tied in to the ED and that is the reality of how he sees himself, but also that is the reality of being the consistent leadership of the department for five years and it is constantly reaffirmed time and time again that he is apart of it as much as it is apart of him.
