Shift operation is a system that allows
employers to schedule work around the clock by using the right work
organization, supervisory coverage, and pay policies. Shift schedules
work best where employees understand and buy in to the operation.
While shift operations always involve having employees working outside
the normal workday, devising the best shift schedule requires looking
beyond the obvious issues of shift duration and time-off scheduling.
An economic analysis of the business to determine the best way to
deploy resources is the first step when starting or reorganizing shift
operations. Management should define its business needs for instituting
or reorganizing shift operations. These may include decreasing costs,
increasing production, increasing safety, and improving the deployment
of skilled personnel across shifts. Various schedule models can then
be devised. Employees can give valuable input on features such as
start times, shift lengths, and day-off patterns. In addition to better
compensation, shiftworkers desire better days off, better alertness
and health, and more predictability in the work schedule. The ideal
goal is a schedule that best blends business needs and employee desires.
Shift differentials. Extra pay for working weekends or nights is a matter of agreement
between the employer and the employee (or the employee's representative).
The FLSA does not require extra pay for weekend or night work. However,
the FLSA does require that covered, nonexempt workers be paid not
less than time and one-half the employee's regular rate for time worked
over 40 hours in a workweek. To make up for the significant interference
with their personal lives, shiftworkers are usually rewarded with
premium pay (known as shift differentials), reduced hours, or both.
Any established premium is considered part of the regular wage and
must be included in computing overtime under the FLSA. A 10 percent
premium to employees who work second or third shift is not unusual.
Figuring shift pay in percentages can be a nuisance, so many companies
pay a flat cents-per-hour wage premium.
Scheduling. The simplest shift schedule divides the day into three relatively
equal parts. First shift might run from 7 a.m. to 4 p.m.; second shift
might run from 3 or 4 p.m. to 11 p.m. or midnight; third shift usually
begins at 11 p.m. or midnight and ends at 7 a.m. or later. It is important
in any system that there be a clear definition of when the workday
and workweek begin and end to prevent confusion as to when premium
rates apply. Employers should analyze their workload to determine
the number and types of workers needed on a particular shift. An unbalanced
schedule may work because more technical, maintenance, and product
changes take place during the day shift. Other scheduling issues to
consider include assigning work in teams that would require consistent
scheduling among many employees, using temporary or part-time workers
to fill in gaps when work levels increase and, in contrast, ensuring
that shifts aren't too sparse.
Variations. There are numerous variations on the three-shift system. One common
system has shiftworkers working 12 hours per day for 3 or 4 days in
a row, then having 3 or 4 days off. Businesses that operate on a continuous
basis may divide the total 168 hours in a week between four shifts
that work an average of 42 hours per week plus an additional multipurpose
crew to cover gaps and special tasks.
Customer service issues. Analysis of workload is crucial in customer service industries,
as shiftworkers with telephone responsibilities interact directly
with customers in different time zones and possibly 24 hours a day/7
days a week for those with Internet responsibilities. Therefore, the
number of employees needed during each hour of the day and each week
of the year should be determined. The average workload, plus possible
high and low variations, also should be calculated by taking into
account holidays, weekends, and vacations. The goal should be to minimize
both idle time and overtime.
Time off. A schedule that includes time off, such as extended vacations or
long “weekends,” can make shift work an attractive alternative to
regular day work. Shift differentials are typically included in holiday
and vacation (or other leave) pay.
Health and safety. Shiftworkers not only work at unusual hours but also work out of
sync with the human body's natural waking and sleeping rhythms. Because
of this disruption, shiftworkers have been found to be less productive,
be more likely to suffer from a variety of health problems--including
ulcers and gastrointestinal disorders, have higher turnover and absenteeism
rates, and have more accidents while working and commuting. There
are few tools for finding employees who are best suited for shiftwork.
While information is now available about how shiftwork affects individuals’
health, care must be taken in applying this information to avoid violating
the American with Disabilities Act (ADA). Employers
may not ask disability-related questions or conduct medical exams
before making a job offer. However, after an offer is made, employees
may be tested as long as all employees in a particular category are
tested. According to the Equal Employment Opportunity Commission,
an employee may be rejected from a particular job, including shiftwork,
for disability- or health-related safety reasons, if he or she “poses
a significant risk of substantial harm to him/herself or others and
the risk cannot be reduced below the direct threat level through reasonable
accommodation.” In other words, if an employer cannot reduce the risk
through an accommodation, the applicant may be rejected. Individuals
supervising shiftworkers should be aware of medical conditions that
are likely to be aggravated by shiftwork. While it might be illegal
to make hiring and other employment-related decisions based on these
conditions, relevant health information can be used for working out
the best schedules for particular workers to improve the overall health
and safety of the workforce. Medical conditions that have been identified
to be worsened by working night shifts include seizure disorders,
chronic depression, insulin-related diabetes, severe gastrointestinal
disease, and chronic heart disease. Other problem conditions include
non-insulin-dependent diabetes, severe thyroid problems, asthma, chronic
bronchitis, chronic sleep disorders, cardiac risk factors, depression,
midlevel digestive disorders, and alcoholism or drug addiction.
Improving communication. Fixed schedules limit contact between employees who only work nights
and managers/supervisors and technical/support staff who only work
daytime hours. If communication between shifts is a problem, your
organization should establish a policy that all managers must work
1 or 2 nights per week. On those nights, their hours need not mirror
the night shift. Rather, they can come in 4 hours earlier or work
4 hours later--just long enough for them to see how things are going
and to deliver news of changes in policies and practices. Don't rely
solely on the nightshift supervisor to disseminate information to
night workers. Instead, put up a bulletin board in a centralized location
that serves as the plant's daily "State of the Union" address. To
avoid information overload, post only important items--key production
and performance numbers, major policy changes, important company news,
etc. Save less significant news--such as minor policy changes and
social event announcements--for a separate site. Meetings with workers
should be held before work, even though it means managers have to
come in at night. After the night shift, workers are likely to be
so exhausted they will miss half of what the manager is telling them.
Studies have shown that employers with shift operations can operate
more profitably by providing assistance to their shift employees.
Shiftworkers are apt to have problems sleeping, difficulty finding
child care at nontraditional times, less training and supervisory
support, and limited access to support departments, including the
Human Resources department. Employers that address these issues can
experience lower absenteeism rates, better safety records, and reduced
errors at work.
Skill imbalance. Seniority-based schedules can leave young, inexperienced workers
on the night shift, which may lead to safety and productivity problems.
The following approaches may balance the team. With fixed shifts,
the importance of front-end training increases. Employers need to
make sure new hires receive the training they need to do their jobs,
as well as information about coping with the physical and social challenges
of working evening and night shifts. Some companies have "pay-for-knowledge"
programs in which salaries are based in part on how many jobs an individual
can perform. This is a highly effective way to encourage employees
to broaden their skills. If skill imbalance is still a problem, an
employer will not be able to use a straight seniority-based system
in which experienced employees work their way onto the day shift.
One alternative approach is to designate certain key positions as
"non-seniority-based." With these jobs, make it part of the institutional
policy that working at night is part of the job and that transferring
to days is not an option. With such a policy, people won't apply for
this job if their goal is to eventually switch to days. Another possibility
is to require day shiftworkers to spend time on the night shift. Depending
on the situation, talented, experienced workers might spend a couple
of days a month or several weeks a year training less experienced
nightshift employees. Just make sure to map out the dates for these
sessions well in advance so veteran employees can plan accordingly.
A related option is to actually rotate a job slot through the different
shifts. Such a system might put an experienced worker on the night
shift for a month or 2 each year.
