[I] These studies show that not all hours are created equal. The research suggests that harm may occur past a certain point. A four-day week causes workers to squeeze more hours than usual into a day. For workers who are already prone to overwork, the additional burden of compressing five days into four could literally break the camel's—or worker's—back.Is the Stress Worth It?[J] Besides the health issues, employers and workers also need to consider the effect that compressing hours into a four-day period has on workers' mental health, stress levels and fatigue. Occupational psychologists realize that people do not function as effectively when tired or stressed. This may be even more of a concern for older persons. Moreover, just squeezing five days of 10-hour-a-day work into a compressed 40-hour schedule can create more rigidity and reduced flexibility for families and children. For example, if the two additional work hours per day are added onto a conventional day schedule that begins in the morning at approximately 8 or 9 a.m. and extends into the late afternoon hours at about 4 to 5 p.m., then many working parents will lose the ability to interact with their children just at the “prime time” of about 5 to 7 p.m. when kids otherwise would be most likely to be in the house and potentially available to socialize with their siblings and parents – before their bedtime arrives.[K] There are many obvious ways to address these concerns and make life easier for workers and their families. Don't overwork. Don't stay too long at work. Find a job with an employer that has flexible working hours. I don't know about you, but the prospect of a four-day week scares me. I already have a hard enough time getting my regular weekly work done over five days. And it's always so tempting to glance at my work email—just a couple more notes to jot down. Instead, why not just pull back at a certain point? Maybe it's time to take Friday off every so often. How about ending work at noon on Fridays, as is the practice of many Jews, to bring in the weekend in a gradual way? The trade-off, if necessary, would involve adding a small increase of one hour per day to the normal Monday through Friday schedule. That approach is actually my personal favorite.
