British service personnel and civilian defence staff are being instructed to step away from their workstations for ten minutes every hour, swap lengthy messages for concise updates peppered with emojis, and follow a strict eye‑care regimen, all in a bid to curb visual fatigue and mental strain. The new guidance, issued by the Ministry of Defence (MoD) and circulated to anyone operating drones, managing cyber defences, or analysing intelligence, marks a fresh approach to workplace health in an increasingly digital battlefield.
Screen breaks and emoji etiquette
Under the fresh rulebook, display‑screen equipment (DSE) users are told not to hoard rest periods but to allow “short natural breaks” of five to ten minutes each hour. The document makes clear that these intervals must be taken regularly; managers are expected to intervene if staff neglect them, even outside the standard lunch break. In addition to the timed pauses, personnel are encouraged to replace long‑winded internal communications with brief updates, a practice that the guidance suggests can be lightened further by the inclusion of emojis.
“You should allow yourself short natural breaks (ten minutes in every hour) away from the DSE,” the guidance states, before adding: “If a DSE user is not taking regular breaks, then the manager is to explain the need for regular breaks and make sure that they are taken.” The intention is to protect against the kind of eye strain and mental overload that can accumulate during long shifts watching screens, piloting unmanned aircraft, or poring over intelligence feeds.
Posture, eye care and safety beyond the screen
The rulebook extends well beyond timing, offering a suite of recommendations designed to keep staff comfortable and safe. It advises against crossing legs or ankles, insisting that feet remain flat on the floor to maintain proper posture. The “20‑20‑20” eye‑care rule is mandated: every twenty minutes, personnel should gaze at an object twenty feet away for twenty seconds, a technique proven to reduce digital eye strain. Even movement off‑site is scrutinised; soldiers are warned not to stare at mobile phones while walking, a habit that could lead to “slips, trips, and falls”. The guidance also flags fire risks linked to charging devices via extension leads and requires formal risk assessments before introducing appliances such as kettles, toasters, coffee machines, or desk fans across MoD premises.
These measures, while seemingly mundane, are presented as part of a broader effort to keep staff “fit, ready and able to perform at their best”, according to an MoD spokesperson. The department has been issuing screen‑related guidance since 2016, framing the latest updates as a continuation of a long‑standing commitment to employee wellbeing.
Veteran backlash: a ‘nanny state’ critique
Not everyone welcomes the new directives. Former lieutenant colonel Stuart Crawford, who spent two decades in the Royal Tank Regiment, described the guidance as a “nanny state” overreach. “I think it’s ludicrous. I think it’s really stupid. ‘Don’t cross your legs’? Sorry, I can’t stop laughing at it,” Mr Crawford told The Times. He imagined the absurdity of confronting troops two decades ago with such trivial advice: “I would have been laughed out of court.”
Mr Crawford’s concerns go deeper than leg‑crossing. He argued that the MoD’s focus on screen‑time stress risks downplaying the far more potent pressures of combat. “It is highly likely most of the mental stress will be coming from soldiers physically fighting. I don’t think we should play that down. That’s why so many former military people suffer from various levels of PTSD and so on.” He contended that sitting in a UK airfield container, monitoring a screen or radar, cannot compare to the trauma of being on the ground under fire. “There is a bit of nanny state about that,” he concluded, suggesting the guidance misses the real battle‑field pressures.
Practical safety measures beyond the screen
While the emoji and break policies have attracted the most headlines, the rulebook also tackles everyday hazards that could jeopardise operations. The prohibition on phone‑gazing while walking is part of a wider safety drive aimed at preventing accidents in high‑alert environments. Similarly, the ban on extension‑lead charging and the requirement for risk assessments before introducing electrical appliances are designed to mitigate fire risks that could disrupt critical facilities.
The emphasis on formal risk assessments reflects a broader cultural shift within the MoD, where even minor equipment—like a desk fan or a coffee machine—must be vetted before use. This systematic approach, officials say, ensures that the focus remains on mission readiness, even when addressing seemingly trivial concerns.
Why it Matters
The Ministry of Defence’s new health‑and‑safety guidance highlights a growing tension between modern military life and the psychological demands of digital warfare. As soldiers increasingly operate from screens rather than frontlines, the armed forces are forced to confront the unseen toll of prolonged concentration, eye strain, and the relentless flow of digital communication. While the measures aim to protect wellbeing and sustain operational effectiveness, the sharp criticism from veterans underscores a broader debate about what truly supports service members—whether it is the minutiae of posture and emoji use or the profound challenges of combat trauma and PTSD. This conversation matters not only for the UK’s defence workforce but also for how societies balance technological advancement with the human cost of keeping their protectors healthy and resilient.
