|Abstract: ||Statistics provided by the Department of Social Security in Great Britain show that the number
of days of certified incapacity because of musculo-skeletal diseases rose from 34.2 million days in
1971/2 to 78.2 million in 1986/7. This alarming rise is costly both to the employee and the employer.
This paper describes how one large-supermarket store examined the extent of the problem
experienced by their staff and what measures the management took to alleviate the situation.
The great majority of studies concerning supermarket workers have examined only the cashiers'
workstations (e.g. Wilson and Grey, 1984; Thorne and Russell, 1987, Krueger et al, 1988; Strasser
1990) often because of the introduction of laser scanning systems. The cashiers were typically found
to report discomfort in the neck, shoulders, arms and back. A recent study by Ryan (1989) examined
supermarket employees in a range of job areas and concluded that the cashiers experienced an excess
prevalence of musculo-skeletal symptoms compared to other employees, particularly in the lower
back and lower limbs. The discomfort in the lower limbs was associated with standing (whereas the
other studies cited examined seated cashiers) and there appeared to be a threshold effect of about
50% of time spent standing for lower limb symptoms to appear. Earlier work by Buckle et al (1986)
compared the incidence of musculo-skeletal disorders within female occupational groups including
supermarket workers in general. It was pointed out that the supermarket workers showed only
slightly lower prevalence rates of back pain than nurses who are known to be a group particularly at
