I work at Intel testing pre-production and engineering samples. I have to pass through a badged entry any time I pass between the 3 labs I work in, and that's after badging in at the front door. Not only are you not allowed to leave your own cell phone on your own desk if you walk away, you can't leave your laptop open if it's unlocked. You're required to use a privacy screen when you're away from your own cubicle. If you walk away from your laptop and someone wants to be really assholish, they could pick up the laptop, take it to security, and say they found it. Depending on what you're involved in, you might get a slap on the wrist from your super for leaving sensative data exposed. There's a 90 minute presentation on security that you have to take a test about before being given badge access to these labs.
The rules go on and on and on, believe me. It sucks.
However, I've had Engineers who think they're king shit and god's gift to the world come over and just pull the ethernet out of my workstation and plug it in to a different station controller because they want to run a quick test. Thanks assholes! Now my batch testing results (that just happen to be the highest priority) are gone, without the ability to save my work so I have to start over. That means my boss is going to come screaming at me why the batch isn't done yet. :roll:
Work is for work. Do your job and go the fuck home if you want to mess with other people. A simple, childish prank that would be AWESOME to play on your mother or someone else who doesn't know how to right-click would be hilarious to pull at home, but can very easily snowball into trouble at work. There's a time and a place for acting like a child and it's not on the clock
