I once had a job where my job time shifted earlier during the course of a week. I was losing a sense of time and always felt tired. We've learned more about human constraints with work and time since then. But my daughter experienced a similar shift in schedule this past year. It would be nice if guidance and suggestions could be offered to help bosses do the right thing, but unfortunately laws are needed for those deniers who are willing to risk the health of their employees as well as the profits of their companies to do the right thing.
