First off let me say that I \[F35\] myself am bipolar, but I am managing it through medication, lifestyle choices (no drugs or alcohol, good sleep habits) and emotional support from my family.  I work in a busy deli in a grocery store and we have a new hire \[M39\] who is VERY unstable. He told me on his second shift that he is bipolar and struggles with manic episodes. He also drinks heavily, does hard drugs, and admits to being "an asshole" (his word not mine).  He has frequent outbursts where he yells and swears and throws things, pacing back and forth wildly, singing songs at the top of his lungs, and acting generally quite unhinged. He does this every time he works. The managers have been told and they will not discipline or fire him, since we are so short staffed. How do we handle this sort of behavior on shift? What would a psych nurse do? I feel like he should be in inpatient care, not working a job with people and knives.
