<p>Stop.&nbsp; Look at the person.&nbsp; How are they in other areas of their life.&nbsp; I am not sure that the job is the issue and possibly the behaviors are reflective of disfunction/stress from another source.&nbsp; Refer to HR for another form of intervention.&nbsp; Nothing makes a stressed out person more stressed than having a cheerleader in their face.&nbsp; You care and you want to help, but it's time for help from outside.&nbsp; Remain positive and approachable, not judgemental.&nbsp; You will find your answer.</p>
