1. Introduction
There was a time, not so long ago, when asking to work from home two days a week felt like asking for a favor. That time has more or less passed. Flexible working arrangements (FWAs) — variation in when, where, and sometimes how work gets done — have moved from the margins of organizational policy to somewhere near its center, driven by a mix of technological change, shifting worker expectations, and, more recently, a pandemic that made remote work a default rather than a request (Almeida, Santos, & Monteiro, 2020; Burchardt & Maisch, 2019; Hunter, 2019). What is interesting, though, is that this shift has not been accompanied by a correspondingly clear answer to a fairly basic question: does flexibility actually make people more productive, or does it just make them feel better while quietly costing them something else?
Part of the difficulty is that flexibility does not act alone. It interacts with something harder to pin down — employee experience (EE) — which is less about satisfaction scores and more about the cumulative, often unspoken sense employees form of whether an organization actually supports them, from the moment they are hired to the moment they leave (Farndale & Kelliher, 2013; Plaskoff, 2017; Panneerselvam & Balaraman, 2022). This lens matters especially in flexible settings, where the usual signals of supervision and presence are weakened or absent altogether, and where an organization's care (or lack of it) has to be communicated through other, subtler means.
The Job Demands–Resources (JD-R) model offers a reasonably tidy way to think through this. Originally developed to explain burnout and engagement, the model treats every feature of a job as falling, more or less, into one of two buckets: a demand, which costs energy, or a resource, which replenishes or channels it (Bakker & Demerouti, 2007, 2017; Demerouti, Bakker, Nachreiner, & Schaufeli, 2001). Cognitive overload and unclear boundaries between work and non-work are demands, and left unaddressed they tend toward exhaustion (Crawford, LePine, & Rich, 2010; Schaufeli & Bakker, 2004). Autonomy, constructive feedback, and social support function as resources — the kind of thing that lets people meet high demands without being ground down by them (Bakker, Demerouti, & Schaufeli, 2003; Bakker, van Veldhoven, & Xanthopoulou, 2010; Caesens, Marique, Hanin, & Stinglhamber, 2016).
What makes FWAs a genuinely interesting case for this framework — rather than just another convenient application of it — is that flexibility seems to intensify both sides at once. Autonomy over one's schedule can deepen a sense of ownership and connection to organizational purpose (Bakker, Hakanen, Demerouti, & Xanthopoulou, 2007; de Leede & Heuver, 2016). But that same loosening of structure can just as easily blur the line between a workday and the rest of a person's life, and the interruptions that follow are not trivial (Evanoff et al., 2020; Majumdar, Biswas, & Sanyal, 2020). It is this duality — flexibility as both gift and burden, sometimes within the same week for the same employee — that makes FWAs worth examining specifically through a demands-and-resources lens rather than treating them as a uniformly positive policy lever.
The empirical record, for what it is worth, reflects this ambivalence rather than resolving it. Broad reviews tend to associate FWAs with higher satisfaction, engagement, and perceived productivity (Allen, Golden, & Shockley, 2015; Bilotta, Cheng, Davenport, & King, 2021), yet closer inspection reveals a persistent undercurrent of strain — difficulty disengaging, a creeping sense of always being available (Hunter, 2019; Messenger, 2017). The COVID-19 period made this especially visible: many workers welcomed the loss of a commute and the gain of autonomy, while others described a workday that no longer had edges (Green, Tappin, & Bentley, 2020; Huws, Spencer, & Syrdal, 2017). Taken together, these findings suggest that flexibility's mere presence guarantees very little; it is the quality of the experience surrounding it — the demands-versus-resources balance — that seems to determine the outcome.
Management strategies (MS) appear, across this literature, as something close to the deciding variable. Structured check-ins, clear communication, and genuine (not performative) feedback can amplify existing resources while dampening the weight of demands (de Leede & Heuver, 2016; Lautsch, Kossek, & Eaton, 2009; Shipman, Swanepoel, & Maynard, 2021); their absence, conversely, tends to breed ambiguity and, eventually, disengagement (Richardson & McKenna, 2014; Mann & Holdsworth, 2003). This is consistent with the JD-R model's broader claim that resources do not just enable performance directly — they also buffer the cost of demands when those demands are high (Bakker & Demerouti, 2017; Demerouti & Bakker, 2011).
This review, then, does not attempt to settle the question of whether FWAs "work." It attempts something more modest and, arguably, more useful: to trace how opportunities and challenges within flexible work map onto the JD-R framework, how management strategies moderate that relationship, and what an illustrative empirical case can tell us about the shape of these effects in practice. In doing so, it aims to move the conversation past the flat question of whether flexibility helps, toward the more productive question of under what conditions, and through what mechanisms, it actually does.
