In 2015, Łukasz Wirkus’s monograph titled ‘Stress in the work of a probation officer. That is why it needs to be emphasized that Łukasz Wirkus’s book is the first thorough Polish study of the issue of probation officers’ job stress, even more valuable if we consider the fact that it is an empirical study. The author stresses that the relation between a probation officer and their subject is a very peculiar one, often fortified by enormous individual costs. It is connected with the nature of a probation officers’ work but their personality construct, which evaluates the effectiveness of the undertaken tasks, is also extremely important in this context.
