I am looking for empirical evidence on the topic. Id generation Z globally sharing similar values, beliefs and perception of volunteering or national culutr still matters?
I don't know if this is the sort of thing you want, but wondered whether you had been this article, as it is what you are looking at:
Cho, M., Bonn, M. A., & Han, S. J. (2018). Generation Z’s sustainable volunteering: Motivations, attitudes and job performance. Sustainability, 10(5), 1400.
I published research in 2019 that used the Schwartz Theory of Basic Human Values and associated PVQ survey instrument to examine generational differences in the values preferences of emergency service volunteers in Australia.
