Working Standing Up
Standing is a natural human posture and by itself poses no particular health hazard. However, working in a standing position for long periods of time and on a regular basis can cause sore feet, swelling of the legs, general muscular fatigue, lower back pain, stiffness in the neck and shoulders, all in a relatively short time. These are common complaints among salespeople, machine operators, assembly-line workers and many others whose jobs require prolonged standing.
There is no single, ideal body position for working. Constant sitting is not the safe alternative to constant standing, in fact prolonged sitting is a risk to health and safety as well (see Sedentary Work). For the best health and safety outcome, workers should be able to adopt a variety of positions – that is to have the option to sit, stand, move around and vary the nature of work tasks. It is important for the worker to be able to equally distribute loads on different parts of the body, with no physical strain.
