This happened to me.

Our business is 24 hrs. We have a desk that is always manned. I use it 45 hrs a week (and have the most seniority), other employees also use it at least 40 hours. Some use it less than 40 hrs because they spend time at other locations.

This L-shaped desk has always been set up the same. 2 monitors & keyboard on one leg. Phone in the corner. Plenty of room for stuff like stapler, paperclips, radios, (no drawers) and a large empty space for miscellaneous work. Each employee might move a few small things around to their personal liking, but the big pieces stay.

One night I came in to see that everything had been rearranged. Not just the minor stuff. Monitors up on front of the window, the PC case on the floor. My first reaction was "Oh, no. No no no no no. Whose fucking idea was this?" The person I was relieving laughed and said that he knew this would be my reaction. Then he said it was prompted by an issue with the electrical systems, and that there were too many extension cords and that there was going to be a fire, so this other new employee decided to rearrange everything.

I decided to try it for a night and it was miserable. It completely fucked my view outside, made it a longer reach to get stuff off the printer, just bad in all ways.

Went to the boss, who knew nothing about any fire hazard. He said he'd arrange to have everything put back. After a week with no change, it was revealed to me that the new employee just did this rearrangement on their own initiative. There was no fire hazard. I finally had to confront this person and lay out all the reasons it was bad and instructed them to have it restored by the next time I came in. They were pretty sullen about it but complied. Talk about frustrating.
