Working with the mentally ill...No, not patients, other RN's

Perhaps it's because the ICU draws a *certain* type of personality (ie: An ADHD person's dreams-multiple flashing lights, alarms, people, tasks...its like XBOX 360 only far less enjoyable, or a type A/OCD person's heaven), or is it the environment that creates the psychopathology?? I'm not so sure ....

Either way, my question is: How do people deal with *difficult* personalities in the workplace? I would say overall everyone I work with is easy to get along with, but one or two nurses are really hard to predict. I don't know weather Suzie Q is having an "everyone walk on eggshells around me" day or "why isn't anyone talking to me?" day. I see my other teammates arguing over who has to hand off their patients to her, because no one wants to give her report...I'm wondering why we don't just tell her to stop being such a butt head? And then another teammate Jane D is a little heavy on the drama queen, bringing her personal life issues into the workplace and throwing little hissies over patient assignments she perceives to be unfair, or how unfair her schedule is, and so forth.

Don't get me wrong, I'm all for people with eccentric personalities-it keeps things interesting. But its a little bit lame for everyone to have to decipher weather a certain employee is in their manic phase all the time. Why does everyone have to adjust their roll so as not to set one or two people off on a General Hospital drama fest? I believe certain issues have already been taken to management with little resolve. So I guess I'm looking for some behavior modification techniques other than me slipping mood stabilizers into Suzie and Jane's leftover spaghetti.
