Call Center Ergonomics: Sit-to-Stand Workstations

Moving up and down for ergonomic effectiveness ...

"Who hasn’t at least at one time thought, “I can’t stand to sit at my desk any longer”? Call center employees spend the majority of the day sitting at their computer. A fresh look at Sit-to-Stand workstations provides a unique twist on the benefits of call center ergonomics for employees. This article discusses how frequent position changes can help to prevent work-related repetitive stress injuries and how to incorporate ergonomics into workstations.

To back up a little, what does ergonomics really mean? Essentially, ergonomics is designing the workplace to maximize productivity by reducing user fatigue and discomfort. Relative to a call center, ergonomics means designing computer workstations that allow employees to be comfortable, and thus productive, while spending the majority of the day at their computer. Since people vary greatly in size, and spend most of their day in a stationary sitting position, incorporating ergonomics into workstations that accommodate various sizes of employees can be a difficult task.

Previous thought on proper ergonomic positioning was that a static sitting position with the body in 90 degree angles was best. New studies show that any fixed position will increase muscle fatigue, and that one key component of proper ergonomics is movement. Some examples of healthy movements are adjusting a chair or backrest, stretching fingers, hands, arms, and torso, looking away from the monitor, periodically standing up to walk around for a few minutes, and switching between a sitting and standing position. Movements such as these promote circulation and reduce muscle fatigue. Frequent position changes can help to prevent work-related, repetitive stress injuries. The most ergonomically correct workstations are easy to adjust, and encourage individuals to change positions frequently.

So what is the easiest way to provide an ergonomic workstation solution? The best way to provide the most varied amount of position changes is with an adjustable height workstation that includes a monitor arm and keyboard mechanism. There is some misconceptions that the only way to provide an adjustable height workstation is to have the entire workstation move up and down with either a crank or push button power mechanism.

There are several problems with this solution. The first problem is that it is costly to have an entire workstation move up and down. Powered workstations are convenient, but also add significant cost on a per station basis. Second, it can be time consuming and difficult to adjust the height of a workstation, which means that the majority of people will not take the time to adjust it. Third, the entire worksurface having height adjustability by moving up and down in a singular motion is not necessarily the most ergonomic solution since the other components of the station may not have the capability of being adjusted independently of one another.

However, with the correct tools, standing is as simple as sitting. The easiest way to create workstations that transition from standing to sitting is to use a keyboard tray and monitor arm with enough adjustment to be used while in a sitting or standing position. This set-up, such as the one shown here, can accommodate 95 percent of the population."    (Continued via, Jennifer Way)    [Ergonomics Resources]
