The study responds to the need to deeply understand how HR practices, particularly high commitment work practices (HCWP), influence two well-being dimensions: burnout and work engagement of European employees. This research also explores the role of age and gender differences, with the purpose to obtain a more shaded framework of the effects of the HCWP and whether these practices have different effects on the well-being of younger, older, male and female employees. The importance of the research lies in the willingness to investigate the influence of demographic factors not only limited within the borders of a single country or for a particular position, but within a European context considering several kinds of jobs. The harmonisation and influence which European countries are experiencing in any field, make this research project of easier generalisation, especially for international enterprises and their HR managers (Bainbridge et al., 2017). Furthermore, the rapid ageing of the population leads to wonder how to manage older workers who may have different needs and priorities, hence which HR practices are more suitable to efficiently cope with this transition (Chand et al., 2019). In addition, gender role dynamics are in continuous evolution across years and need to be considered in the definition of a HR work system since responses to them may differ (Shin et al., 2020).
