Abstract

This paper concerns the problem of generation gap management resulting from personnel restructuring in foundries in Poland. Structural changes to steelworks led to a sharp decline in employment caused by decreased steelworks production. New hiring was limited as a part of employment rationalisation in the steelworks sector. Such personnel policy eventually led to a generation gap. Ratios between individual age groups of employees are imbalanced at steelworks: the numbers of young personnel are low and of those aged 50+ are high. This research forecasts changes in employment levels for the 2013-2019 period, aimed at closing the generation gap. The paper consists of three parts: (1) a descriptive analysis of labor market demographics in Poland’s steel industry; (2) proposed methodology for HR management model, and (3) econometric models forecasting labor demographics in Poland’s steel industry.
