Previous research on the problem of the influence of “new” workers, i.e. workers with little experience, showed
that the observed group of workers generates increased injury risks to a considerable extent. Levitt and Samelson [2]
determined that 25% of injured construction workers have less than 2 months of working experience, whereas 6% of
injured workers have between 2 and 3 months of working experience. According to the Health and Safety Executive
of Great Britain, “adequate experience makes a significant part of competence. It is more likely that the workers will
adopt a safe way of working if they are familiar with the reasons why it is necessary”. [3]The research carried out by
the National Safety Council of Nebraska which encompassed 143 national companies in the USA showed that the
occurrence of injuries among new workers is by 52% higher if they had not undergone the training process
compared to those workers who had been trained.
