This paper focuses on the reality of very small and small enterprises (VSSEs) in Brazil, concerning health and safety management of their workers. These companies tend to operate in a few administrative levels. The owners' health and safety culture is fundamental for the implementation of preventive measures. The VSSEs end up adopting merely reactive and under-the-law actions. In order to understand such reality, a questionnaire was elaborated especially for the research made. Fifty-five very small and small enterprises of the industrial, commercial and service sectors were selected. The research confirmed the reactive attitude shown by the VSSEs, thus demonstrating that none of the companies involved presented policies of safety and health. Even though not holding policies, programs or scopes of their activities, 22% of them revealed to have a clear definition of the responsibilities of their high level administration. Nevertheless, 10% had financial resources allocated to this sector. Such companies do not count on a frequent safety and health support. The ignorance on it leads them to take a reactive action. This study reaches its objective on contributing to the debate, besides indicating that the way to improvement is on the strict cooperation between governments, companies, workers and society.
