Regardless of their specific business, white collar workers have some factors in common: they work seated without moving for a long time, they use certain arm and hand muscles excessively, and they tend to keep a poor body posture. The resulting Musculoskeletal Disorders (MSDs) produce discomfort, and even pain. This study aimed at an ergonomic assessment of white collars of a Portuguese company – to identify the most critical points in old furniture designs and working posture habits. An evaluation was done in the administrative department using a random sample; the anthropometric and furniture measurements were taken and compared. The RULA method was used to evaluate the risk arising from adoption of a poor posture at the workplace. The results obtained show a prevalence of symptoms of MSDs. The furniture is oversized in most cases. Adoption of a poor posture at the workplace requires a short-term intervention. There is a significant association between MSDs and wrong-dimensioned furniture, besides habit to adopt wrong postures. This company (as many other SME’s) must change the old style office furniture by one with dimensions matching workers’ anthropometry, and provide training on best practices to maintain good posture at work
