<prompt> Human: Dont know where to go for this.i thought pf might help .My co worker, who I have to partner up with, does not care about anything. He doesnt pull his weight and doesnt know anything. Hes just generally lazy too. He also was never held accountable for his actions. He just started on the same shift as me last year. He almost got us both fired by not bringing up a problem that could have became an emergency. He also is the type of guy to flip breakers on when I work, drop a heavy peices of equipment on me and not give any concern to safety. I am guilty of association when he messes up. Im not sure what to do. Im thinking about trying to move to a different shift or looking for another job.  <response>: Go to HR and document your concerns. This will be of major concern for them.
