There was a place by me. Big factory might have even been government owned back in the day, but it was unionised. It used to be 9-5 or maybe double shifts. They wanted to change it to 24 hour production, 12 hour shifts. The workers fought it hard but the option was change the shift pattern or the factory will have to close due to not being profitable.
Anyway they changed and everyone that fought the shift ended up loving it. Turns out people really like the extra days off with those shifts.
Same as another business I worked for. I asked the factory manager (who came up from that shift pattern) about changing some people over for a few weeks onto days to get some work done. He said you'd have to pay them extra to move to days. People love the shift pattern.
It seemed to me preferable to change the pattern every two weeks but apparently the reports said every 1 is better because people get too sad that they miss a lot of things in a row.
