As an employee, I have had a boss use a one on one meeting to seriously go off at something that was not even factual. From this experience & many others like it, I personally will not enter meetings one on one anymore, there is too much of what he said vs what I said if anything goes wrong. I have even over heard two boss's discussing how to get people to do what they want, which included pulling a employee in to a room for a one on one meeting, berating them & saying what ever they want, knowing it was the employee vs them when it came to who said what. In one instance I had a problem with a team leader, his boss just backed him & HR backed them both instead of listening to anything I had to say - how should one deal with these situations?
