Warning!
Ever since I placed this article on this website,
it has received more hits than any other page. However, I think it is the least important
page on the site.
To be sure, there is a time and place for job
rotation and under certain circumstances the system can work well. But
it is a mistake for you to only consider job
rotation as a solution to problems.
Job rotation alone does not change the risk factors present in a
facility. Moreover, it does little by itself to stimulate
innovation and efficiency.
Finally, job rotation might seem like an easy way to reduce the risk of
musculoskeletal disorders
(MSDs), but to do it right can take a lot of work.

Introduction
There are many reasons for
implementing a job rotation system, including the potential for
increased flexibility in production, increased employee satisfaction
and lower MSD rates. However, establishing a rotation system that
properly determines job rotations and monitors their safe use is not a
simple task. There are many issues to consider and no official
protocol or methodology to call upon. The successful implementation
of a program requires teamwork from all parts of the organization,
including management, union, medical providers, and especially the
employees themselves.
Many job rotation systems have failed because of
lack of planning and lack of foresight into the problems and
shortcomings of rotation. It can prove more difficult than it might
seem at first glance, since it involves changing the organizational
structure of an entire facility.
The following materials provide systematic guidance for setting up a
rotation system. This guidance should be viewed as a starting point
for further discussion by workplace personnel. Roadblocks
There are two major
categories of roadblocks that are often encountered in setting up a
job rotation system:
Cultural issues
The
first set of difficulties are associated with the challenge of
changing the work structure and not from the job rotation in and of
itself. Examples of problems include:
- Experienced workers not wanting to learn new types of
work.
- Employees not wanting to “lend” their equipment to
others.
- Pre-existing differences in wage levels among employees
whose jobs are to be rotated.
- High-seniority employees who have “paid their dues”
working at difficult jobs may believe that they have earned their
right to easier jobs and may resist going back to more difficult work.
- Practical problems of physically getting from one job to
the next.
Rotation
issues:
The other set of difficulties have to do with
issues surrounding the rotation schedule itself:
-
Difficulties in finding appropriate jobs to rotate to
(for the goal of reducing MSDs)
-
Difficulties for employees in learning the subtleties of
some tasks and thus end up increasing the physical demands.
-
Inability of some employees to be physically able to
perform the most difficult tasks
-
Education and training of workers for new jobs
-
Inconsistency of application
Basic Limitation
Job
rotation alone does not change the risk factors present in a
facility. It only distributes the risk factors more evenly across a
larger group of people. Thus, the risk for some individuals can be
reduced, while the risk for others can be increased. However, there
will be no net change in risk factors present. This can be shown in
the following graph.
When
employees rotate between two jobs the risk exposure can be thought of
as being “averaged.” Job rotation may drop the average to within a
safe level, or raise the whole group in excess of safe limits.
Unfortunately, it is not possible with current knowledge to determine
what the safe limit is. For this reason it is prudent to be cautious
about job rotation. Engineering changes should remain the goal of the
ergonomics program.

Limitations
If the jobs being rotated involve the same muscle-tendon groups then
the benefit of MSD risk reduction is lost. Thus, rotation among jobs
that are similar is not appropriate. Situations that are best able to
benefit from job rotation are those where, for example, a wrist
intensive task is adjacent to a back-intensive task.
Additionally, if the rotation is too infrequent, such as a daily
rotation, the benefit may also be lost. Typically, employees should
rotate every two hours. An hourly rotation is probably better and a
four-hour rotation probably the maximum that would provide any benefit
from an MSD perspective.
OSHA Guidelines
The following is excerpted from the OSHA Ergonomics Program Management Guidelines
for Meatpacking Plants:
Job rotation should be used with caution and as a preventive measure, not as a response
to symptoms. The principle of job rotation is to alleviate physical fatigue and stress of
a particular set of muscles and tendons by rotating employees among other jobs that use
different muscle-tendon groups. If rotation is utilized, the job analyses must be reviewed
by a qualified person to ensure that the same muscle-tendon groups are not used.
A "qualified person" is one who has thorough training and experience
sufficient to identify ergonomic hazards in the workplace and recommend an effective means
of correction; for example, a plant engineer fully trained in ergonomics - not necessarily
an ergonomist. In analyzing jobs for rotation, the qualified person must have sufficient
expertise to identify the ergonomic stresses each job presents and which muscles and
tendons are used.
Job rotation can mean that a worker performs two or more different tasks in different
parts of the day (i.e.. switching between task "A" and task "B" at
2-hour or 4-hour intervals). The important consideration is to ensure that the different
tasks do not present the same ergonomic stressors to the same parts of the body
(muscle-tendon groups). There is no single work-rest regimen that OSHA recommends; it must
be determined by the nature of the task.
These excerpts indicate the importance of establishing a formal, documented job
rotation system which carefully matches jobs. This matching system should ensure that
different muscle-tendon groups are emphasized.
Scoring System
For best results, it is
important to quantify or score the risk factors associated with each
of the tasks that are to be rotated. There is no established system
or protocol for these scores and you will need to select or develop a
system that is appropriate for your site and the tasks in question.
Typically, a score would be calculated for each job
for (1) the hand and wrist, (2) the arm and shoulder, (3) the lower
back, and (4) the overall job difficulty. However, other factors and
body parts may need to be taken into consideration depending upon the
tasks.
Whatever scoring system is used, it can be helpful to convert your
final results into “red,” “yellow,” and “green” to represent high,
medium, and low risk. Thus, a good rotation would a job with a red
score for the lower back and one with a green score for the lower
back.
Be Systematic
To
realize the beneficial aspects of job rotation it is necessary to
establish definitive internal guidelines that insure consistent
application and at the same time allow for restricting employees from
rotating into jobs they cannot perform. To ensure that all job
rotations meet basic ergonomics requirements a consistent and
systematic approach is required.
It is
probably best to start slowly at first, such as in a pilot work area
so that the program can be further refined before being implemented
elsewhere.
Steps for Implementation
Step 1:
Hold an employee meeting to
determine interest and gain involvement and input. During this
meeting it would be appropriate to have a short presentation on
ergonomics and job rotation. The purpose here is to build upon the
ergonomics training already received and further it by discussing the
relationship between it and job rotation. At this time it would be
appropriate to issue a Job Rotation Questionnaire (see below).
Step 2:
Calculate the scores for the jobs considered for rotation. Use these
scores to establish which jobs should be rotated with which. In
general, decisions about the suitability of a particular job rotation
should be based on the following:
Step 3:
Apply a common-sense review to ensure that the logistics of the
proposed rotation are suitable and that the job rotation seems
reasonable. Also, review the job rotation scheme with the affected
employees. The employee concerns and insights should be taken into
account. If necessary, changes to the list should be made, and final
approval for the list obtained.
Step 4: Provide employees with any
training that they may need to perform the tasks or handle the tools
and equipment. In general, experienced employees going to a new job
should receive the same training requirements and documentation that a
new hire must have before starting in that position.
Step 5: Provide employees with adequate
break-in time to ensure that they are fully qualified and physically
conditioned to perform their new tasks. Similar to training
requirements, the same guidelines for new hires starting out should
apply to experienced employees starting in a new job. Even if the
employees have performed the job previously, they should generally be
allowed the break-in period to become accustomed to the work again.
The training and break-in period enables the
employee to develop those subtle work techniques needed to perform the
task the easiest way and thus minimize the risk factors. This also
suggests that the number of jobs included in a particular rotation
should be kept to a minimum, perhaps two or three, allowing the
employees to become “experts” at each task.
Step 6: Begin job rotation.
Step 7:
Monitor the new rotation to ensure flexibility and consideration for
individuals that are having difficulty performing new tasks. Assess
if further training, break-in, and/or accommodations can be made for
these individuals.
Step 8: Hold follow-up meetings with
employees to evaluate the job rotation. Survey the employees using
the job rotation questionnaire again. Compare results to the initial
survey. If results are favorable then continue rotation. If results
indicate a problem then decide if corrective action is needed or if
rotation should be discontinued.
Step 9:
Track other measures such as injury rates, turnover, employee
satisfaction, or workers compensation to determine effects of the job
rotation.
Comments
These steps should be
viewed as options and starting points for further discussion by the
site ergonomics team and other interested personnel. This framework
was written with a particular company and industry (meatpacking) in
mind, and you may have different needs and applications. The
objective here is to show you one approach for developing a formal,
consistent, and systematic method of job rotations that are based on
the requirements of the jobs.
To
help you make sure that all of the steps of the process are completed
and documented, you may find it helpful to use the Job Rotation
Checklist found on the following page.
Role of Ergonomics Team
Anyone should be able to suggest job rotations, including supervisors,
production employees, or union officials. However, the job rotation
scheme should be approved by TeamErgo with input from the affected
employees before being implemented.
Job Rotation Checklist
The following must occur for each job rotation set-up.
Jobs proposed to be rotated are:
