I would like to suggest a Safety category.
There we could post accidents that we find in the news, or heven forbid, or own stories.
Actually, I did injure myself recently in a saw. Also I have a friend that tore a big slab of skin off of his arm in a saw last year.
Safety sounds like a boring topic, but when we share true stories it awakes our senses the next day while on the job.
Here's our priorities
Safety is 1st, Quality is 2nd, and production is 3rd.
There is nothing so pressing or important that should cause us to leave at the end of the day injured.
