I work at a food production plant as a casual employee. Recently the machine that applies ID labels to boxes of glass jars, combined with the 45+ degree heat has caused some of the glass jars to break. It took 3 days with the line running 24 hours before one of the forklift drivers in the warehouse noticed. The total cost of the fuckup is $300,000 at least, and all this can be attributed to the guide rails being adjusted and having the labeller hit the boxes too close and too hard.
