What Is a Rotating Shift?

Many shift work positions follow a fixed schedule with the same starting and ending times for each shift, as well as the same work days during the week.

The specific requirements of a rotating shift vary by employer. Some of the most common rotating schedules include:

• Continental: Workers rotate between day, evening, and night shifts for seven consecutive work days. Each shift lasts eight hours. After each block of seven work days, the employees receive two or three days off.
• Panama: The Panama schedule – also known as the 2-2-3 – follows a 14-day timetable. Employees work 12-hour shifts for two or three consecutive days, then receive two to three days off. This means they’ll work different days during the first and second weeks of the 14-day cycle.
• Dupont: A longer rotating schedule, the Dupont system spans four weeks in length. Workers typically rotate between day and night shifts every one to two weeks. They’ll work for three or four consecutive days, then receive one to three days off in a row. The four-week schedule culminates in seven consecutive days off for the worker.

Rotating shifts can be more difficult than fixed shifts because they require workers to readjust their schedule every week or month. That said, the circadian rhythms guiding your sleep-wake cycle can be adjusted more easily when you rotate forward from day to night to early morning shifts. Rotating backward or in a random pattern tends to be more disruptive to circadian cycles.

Some workers also struggle with rotating shifts because they’re forced to adjust their sleep-wake schedule every one to two weeks. For many people, rotating every five to seven days is most difficult. Rotating more frequently – every two to three days or so – causes fewer circadian disruptions, while rotating less frequently allows you to spend more time in one circadian cycle before you need to adjust again.

Pros and Cons of Shift Work

Benefits of shift work often include:

• Suited to night owls and morning people: People who feel more motivated and productive after the sun goes down may thrive during a night shift, whereas people who concentrate better in the pre-dawn hours may benefit from an early morning shift.
• Easier commuting: By avoiding roads and highways during peak traffic times, you’ll be able to get to work more quickly than many daytime commuters.
• Better wages than day shifts: While employers in the U.S. are not legally obligated Trusted Source U.S. Department of Labor The U.S. Department of labor aims to foster, promote, and develop the welfare of the wage earners, job seekers, and retirees of the United States; improve working conditions; advance opportunities for profitable employment; and assure work-related benefits and rights.

Disadvantages of shift work include:

• Sleep problems: Shift work disorder is a medical condition that affects people who work non-traditional schedules. The disorder is characterized by insomnia symptoms when the person tries to sleep and excessive sleepiness when they are awake. Even if their symptoms do not develop into a disorder, many shift workers struggle with falling or remaining asleep during the day when rest is needed and staying awake during their shifts. Hormonal disruptions of cortisol and testosterone levels can affect the quality of life and cause fatigue, low energy levels, and decreased libido.
• Life disruptions: Working at night and sleeping during the day can interfere with family life, as well as socializing with friends or colleagues.
• More hazardous driving conditions: While shift workers contend with less traffic, they are at higher risk Trusted Source National Highway Traffic Safety Administration (NHTSA) Through enforcing vehicle performance standards and partnerships with state and local governments, NHTSA reduces deaths, injuries and economic losses from motor vehicle crashes.
