Attaining work-life balance is one of most important needs or the 21st century global population. The work-life issues have been mostly treated from a sociologic perspective (see for exemple Nordenmark, 2004), a work psychological perspective (see for exemple, Sonnentag and Kruel, 2006; Jones, Burke, & Westman, 2006) and from a business perspective (see for example Kossek & Lambert, 2005). Whereas in the first one the roles of societal values and social structures have been related with individuals' work-life balance, in the second one the roles individuals is in the centre and in the third, the roles of the employing organisations in enabling individuals to reach a balance have been discussed. Even if not that visible on the research agenda, work-life issues also belong to "urban studies". This paper intent to connect lifestyle migration to work/non-work process discussing what could be named as "work/non-work lifestyle migration". Based on the accepted proactive view of the work/non-work process, this paper deems work/non-work lifestyle migration as a "rational" or "cognitive" choices where individuals knowing their work/non-work preferences, will search for a context enabling such preferences to be enacted in a better way for a better outcome. By "finding" the right urban context, individuals, couples and families may have an opportunity to experience a sustainable work/non-work process where the urban context is enabling them reach a sustainable work/non-work equilibrium. Following the reasoning above, cities may use the "work/non-work" argument to attract people while convincing them that their cities, in comparison to others, will represent the "ideal" or "idyllic" context for enacting their work/non-work preferences and reaching sustainable work/non-work equilibrium. By enabling individual's work/non-work process and enabling individuals to reach work/non-work equilibrium, cities may, as organisations, become sustainable economically, environmentally and socially. Such cities could be referred as "sustainable work/non-work friendly cities". However, to what extent are in fact cities aware of their role in enabling people to reach work/non-work equilibrium? To what extent do cities think, "work/non-work" and integrate "work/non-work" while planning and developing the urban context? If cities do so, they may use "work/non-work" arguments in their information to potential migrants. One evidence is the discourse on transport management in urban context that points out how cities aim at reducing commuting time which is an essential component of work-life balance via "time based strain" and participate to the definition of "temporal boundaries". But are their other arguments? The purpose of the paper is to explore the information presented to potential migrants in cities to identify if and to what extent cities include a "work/non-work perspective" into their approach to urban development enabling individuals to reach sustainable work/non-work equilibrium.
