One of the workers in our office was using our 2nd network for personal use during a break, we have a break room computer which we use for personal things during our lunch time / break time however we also have a wifi network if someone wants to bring in their computer to use during breaks.
This employee would unplug the LAN line from the back of our joint use computer and plug it into her MAC laptop because quote "I dont have time"
So its faster for you to root around the back of a desktop, find the LAN cord, sit on the ground next to it to work on your laptop rather than simply type in the wifi password ONCE? Time saving my ass
After she had done this a few times and interrupted several transfers and updates to that computer in doing so I logged onto her mac and input the wifi password for her.
