When I worked for Major Bank, one of the biggest rules we had was that we were not allowed to look up our own accounts on "employee" systems (the mainframe and other systems that employees used to work with customer accounts). We were allowed to use the internet to go to the online banking site, like any other customer, but we were not to use employee systems as a customer (does that make any sense?). The whole reason was to avoid even the appearance of impropriety. We had the power to reverse transactions, move money around, do bank originated credits and debits and all that fun stuff, so to mess with your own accounts could look very, very bad. Also, every movement you make on the computers is tracked, so it would seem obvious that you would get caught in fairly short order. Anyway, one of my coworkers regularly broke this rule. He wasn't doing anything "bad", just balancing his checkbook and such, but still, we'd all been given dire warnings about the consequences of such actions (immediate termination). Of course, CW was caught and just couldn't understand why he was being let go.
