I have had a similar experience. A couple of years ago, I was employed in Human Resources at Target. Several months into my job, I began recieving complaints from management about one of their employees. Apparently, they had an employee who was a troublemaker. Management told me that this woman was constantly complaing about other employees, lying, skipping work, and just generally being a pain to deal with. Apparently, they had caught this employee in several lies before and were scared to deal with her themselves. Finally, we caught this employee stealing while on the job, so we were conveniently able to rid ourselves of this troublemaker. I have dealt with all types of people during my career, but there are no types I dread dealing with more than those I suspect to be either troubled or psycopaths. You don't want to cross these types, as they can be very sneaky and manipulative. They are capable of fooling many people and doing much damage, as they don't have a conscience.
