I had a personnel record for lots of years. It was all perfect. I got into a verbal altercation with a superior one time and he said he was going to make an entry on my records. Well, I kept the personnel records for the department. I went and got my file and put it on his desk. He apologized for being a jerk and I accepted the apology as well as lunch. :)
I can do that all the time if I want and I don't really have to hack into them....I'm cute and live with who I work for and allowed to get in to anything I want when I want.....and only a fool would stop me..... :)D
