Work seniority as a determinant of employment intensity
The purpose of this article is to analyse the intensity of unemployment leaving in relation to the length of an unemployed person’s work seniority. A hypothesis was made that its intensity changes depending of that person’s employment history and on its gender as well as education. The research material consisted of individual data of 21,398 unemployed people registered by the Poviat Labour Office (PUP) in Szczecin in 2012 and observed throughout 2013. The author used the event history analysis, which was conducted in three steps. First, the author assessed the likelihood of remaining unemployed depending on the unemployment period. Secondly, she divided the registered unemployed into groups according to their employment history and determined the relationship between the employment intensity and the span of time when the members of those groups remained registered in PUP. In the third step, she used the average hazard rates to compare the intensities of unemployment leaving in individual groups.
