I recently watched a CNCNY youtube video wherein he toured a machine shop in, iirc, L.A. They make vacuum table fixtures for use in VMCs and such...
They were talking about efficiency in the workplace and how clean the shop was, when the owner said that they didn't clean up, at all, at the end of the day: Instead, they worked until the end of the day, leaving everything as-is, and started each day by cleaning the entire shop.
His stated reasoning was that at the end of the day, everyone was often tired, and relatively inattentive, often having worked late, or very hard, to meet deadlines, etc, so if they cleaned up then they would not focus, would rush through cleaning so they could get home, would do a half-arsed job, etc.
By cleaning at the start of the day, everyone was fresh, attentive, and did a MUCH better job. Makes sense to me. That shop was immaculate.
Likewise, in my own home shop, I often work very late, trying to get something done before bed, so cleaning is, at best, not very thorough. I used to joke that I had to clean up before starting any project... now I do so intentionally. It's made a HUGE difference in my attitude and effectiveness.
