“…There are other research approaches investigating this topic that are acknowledged but have not been considered in this study, such as the person-job-fit literature (Caldwell and O'Reilly 1990) and psychological contract theory (Scandura and Lankau 1997). This article is a small component of a larger project investigating the linkages between work arrangements, work outcomes, job satisfaction, sleep, and health (see Hazak et al 2016; and Virkebau 2017 for some of the initial results) as well as companies' sustainability and competitiveness in the European post-transition economic context at large (e.g., Männasoo, Maripuu, and Hazak 2017;Maripuu and Männasoo 2014;Avarmaa, Hazak, andMännasoo 2011, 2013;Hazak and Männasoo 2010;Männasoo 2008;Hazak 2008Hazak , 2009Männasoo and Maripuu 2015;Laidroo and Männasoo 2014). In that broader context, the results of this article help to better understand the existence and role of differences in working-time-related preferences and choices among different types of employees as well as the different effects that regulation can have in the context of different companies.…”
