The new boundary problem: why employees need psychological detachment, not just flexibility

Purpose This paper aims to argue that many organizations are naming employee exhaustion too narrowly. Workload and flexibility still matter, but many employees are also struggling with a boundary problem: work is too easy to reenter and too hard to leave behind. Design/methodology/approach This study develops a practitioner-focused viewpoint using research on psychological detachment, boundary management, electronic communication and work intensification, alongside observations from hybrid, on-site and technology-enabled work. Findings Flexible work has solved real problems, but flexibility alone does not create recovery. Employees can remain tethered to work through unclear response norms, always-available channels, role spillover and AI-enabled acceleration. These pressures can make employees appear off the clock while still carrying work demands into nonwork time. Practical implications Human Resources (HR) leaders should treat psychological detachment as a work design issue, not a private self-care assignment. This study offers practical actions related to communication norms, manager behavior, recovery cues, artificial intelligence (AI) implementation and employee listening. Originality/value The study reframes work–life balance as a strategic HR question about whether organizations create conditions that allow employees to step out of the work role long enough to recover.
