“…For our research specifically, one relevant aspect of nationality might be how culture changes the way heavy work investors perceive and evaluate their experiences in terms of, for example, being devoted to or obsessed by one's job, working intensely or feeling energetic at work. For instance, factors such as having a Protestant work ethic (Furnham, 1984) might be involved, given that work-related ideologies are seen as responsible for cross-national differences in attitudes towards work and productivity (Czerw & Grabowski, 2015;Hofstede et al, 2010;Kaasa, 2016). Similarly, one might hypothesize that workers from Protestant countries, like the United States, Germany, or the Netherlands (Snir & Harpaz, 2004), are more likely to show higher correlations between workaholism and work engagement components compared with workers from countries with a different cultural background, because we expect these variables to overlap in cultures that strongly and positively emphasize investment in work.…”
