“…Though NWW has been defined during the past two decades in many ways, the term is still used as an "umbrella term," and a comprehensive definition is still lacking. As shown in Table 1, authors who investigated NWW issues differ in their use of the terms "NWW," "flexible working," "flexible work practices" (Kingma, 2019), and "flexible work arrangements" (Blok et al, 2012;Brandl et al, 2019;Schmoll & Süß, 2019;Van Steenbergen et al, 2017). An examination of these definitions demonstrated their diversity, commonalities, and differences (see Appendix B for details regarding the different definitions).…”
