One of the people I manage uses a cordless mouse on their work computer. While that shouldn't be a big deal under normal circumstances, we work for the federal government. So, when you switch out any computer components, they get their feathers a bit ruffled.
One of the tech people came by her cube a few weeks ago and noted that she was using a cordless mouse. At that time, they told her that she really wasn't supposed to be using that mouse without proper approval from a tech person.
This lady on my team is not the kind of person that backs down from any discussion. She's very set in her ways and has no apprehension about stating her mind. It's great in the sense that she's a very independent worker and very reliable. It's not so great when she disagrees with someone.
Fast forward to yesterday. She had requested to have a new monitor installed. A different tech guy than the previous visit came by with a new monitor. Unfortunately, this tech guy has a similar personality to her. He immediately noticed that cordless mouse is hooked up to her computer. He confronts her about the unapproved accessory on her computer. Long story short, they end up yelling at each other in the middle of the office. She eventually became so angry that she stormed out of the building and went home.
So I get to spend part of today calming her down while smoothing over any other issues. Management is bliss.
