In the old days people relied on muscle effort for most of their work in the fields, to defend themselves as well as to train for battle and to wage wars; then after the industrial revolution, all that changed, machines replaced muscles to do heavy lifting, to make efforts to have things done, in agriculture and in every other endeavor; the 6&&1 crumbled, work-life imbalances hit society very hard (people died in the great labor wars, the 8 hour 5&&2 was born, which is not actually working out nowadays as people are moving into intellectual service work; in order to keep in shape, people have to exercise regularly, one day-off one day-on, be physically active, otherwise obesity and illness set in, and the person dies prematurely. To survive people have to work most of their lives on earth while trying to have some R&&R; So we have to research and ask how to optimize better management of our time on the planet: optimum Work/Quality of Life/Balance, we formulate the operations research problem: (1) Maximize productivity levels, performance; and at the same time, (2) Maximize Rest and Relaxation R&&R, better quality of life, personal time; (3) A third worthwhile goal is to have more active, healthier children and adults, less sedentary life and less obesity, to explore optimizing muscle memory retention for the continuous improvement of exercise habits, with much higher probability of having longer life expectancy, longer life span. As a result: minimize stress levels, job and career failures, heart attacks and strokes; then the population becomes healthier, with less obese kids, teenagers and grownups; plus much better finances for the individual, taxes, GDP and society. Monetizing time wasted or lost, by improving productivity, reducing cost, improving relaxation and reducing high stress levels prevalent in society; and all that by better time management solutions, leading to reduced unemployment, boosting the economy and GDP; the Post Office budget and operational problems get a simple solution. Strengthening Social Security, etc. ... The solution is actually a natural convergence of the nurses and hospital staff: (3-1-3-1-4-2) schedule, as well as the police and firefighters' schedules; The Agile methodologies primary goals are: (1) Maximizing resource efforts, (2) Minimizing waste and (3) Maintain high quality throughout the process: THE GOALS MATCH A freshly hired employee could get up to 12 times * (1+3+1) = 5 days off in-a-row every calendar year, that is one 5 days-off in-a-row every month, or 6 times * 9-days-off in-a-row, 1+3+1+3+1 = 9 x (12/2), that is one 9 days-off in-a-row every 2 months. or other combinations, by arrangement with their managers/supervisors. There would be more employment: At any one time a large proportion of the population (up to 30%) have responsibilities for family members, mothers and fathers providing care for infant babies, for the elderly, sick, or disabled relatives, these care-givers might only have 2,3 or 4 days available to work every 7 or 8 days, but at the moment society/businesses offer mostly two categories: full time with benefits, or welfare; As employers do not offer much part/time work because of the rigid, inflexibility of the 5&&2 structure, plainly there are no incentives for the care givers but to go or stay on welfare. The 3&&1 schedule offers much more flexibility, mainly it has finer granularity of almost half the blocking factor at 4 days in-a-row, instead of the present 7-days in-a-row coarse blocking factor. That is in the 3&&1 we have much smaller blocks that people can mix and match more freely and more easily for work and/or for rest. Two (2) workers, each working half/time, part-timers, could work as one full time staff position, similar to: (3 + 1) + (3 + 1); one person works the first shift of 3 days in-a-row, a second person would work the second shift for 3 days in-a-row. There would be more available work in the category above."
