Trying to identify a short story. I recall it was quite short, shorter than a novella. I read it within the last few years, but my impression is that it's from the second half of the twentieth century, maybe the sixties. I can't recall if I read it online, in an anthology, or collection.
Set in America, a middle-aged man stumbles on a team (maybe like dwarves or gnomes) whose job it is to set up the world for the next day by removing all the previous day's "stuff", like street furniture? (I know that makes no sense). He disrupts this process and somehow prevents progressing to the next day. I also remember the story was quite lighthearted with the team behaving in a very grumpy way like interrupted workmen.
I thought the title was something like "What happened to Tuesday" or similar. For some reason, I thought it was by Keith Laumer, but a search doesn't reveal anything.
The trope was similar to "The Tunnel Under the World" by Pohl, and "The Adjustment Team" by Dick, in that reality was constantly changed and controlled by an organisation of some kind.
