In years following the 2008 recession, many Americans are still scrambling to find enough work hours to make ends meet. One emerging trend is “clopening,” when an employee works the closing shift, then opens the same business a few hours later. Piled on top of commuting, trying to get some sleep, and attending to family duties, the few remaining precious hours between shifts are overbooked. That can have negative consequences on health. Sociologist Gerhard Bosch tells the New York Times about the European Union’s required 11-hour rest period between shifts: ““If a retail shop closes at midnight, the night-shift employees are not allowed to start before 11 o’clock the next morning.”

Even though some unions in the United States have negotiated similar required “between shifts” time, there is not yet a national labor law. However, several states have taken steps toward Right to Work laws some hope will alleviate the long, inconsistent hours many employees face.

Some business owners claim that some employees prefer “clopening” to working 9 to 5, pointing, for example, to students with busy daytime class schedules. However, one student worker told the Times that working on the clopening schedule meant quitting his pursuit of a master’s degree—he’d lost focus and developed chronic exhaustion.
