Multitasking Risk: 5 Myths HR and EHS Must Drop

Multitasking risk is the psychosocial and operational hazard created when a worker or leader must handle competing tasks, alerts, decisions, and interruptions at the same time. In safety critical work, it is not a productivity nuisance, because split attention can weaken risk perception, verification, supervision, and emergency response.

EU-OSHA describes psychosocial risks as risks that arise from poor work design, organization, and management, and multitasking sits exactly in that design layer when the job demands simultaneous attention instead of sequenced control.

This article challenges 5 myths that HR and EHS teams still accept, then shows how to turn multitasking from an individual performance problem into a work-design and safety-culture decision.

Why multitasking risk is not a soft issue

Multitasking risk becomes a hard safety issue when competing demands reduce the quality of decisions, checks, handovers, and field supervision. ISO 45003, published in 2021, places workload, work pace, and job demands inside the management of psychological health and safety, which means EHS can no longer treat attention overload as a private weakness.

ISO specifies ISO 45003 as guidance for managing psychosocial risk within an occupational health and safety management system. The practical consequence is direct: if a 12-hour shift requires a supervisor to approve permits, answer production escalation, respond to people issues, and review critical controls at the same time, the risk belongs in the system, not in a coaching note.

As Andreza Araujo argues in Safety Culture: From Theory to Practice, safety culture is revealed by routine decisions, not by values printed on the wall. Multitasking exposes that truth because a culture that praises speed while asking for careful verification has already decided which value wins when pressure rises.

1. Is multitasking just a productivity problem?

Multitasking is not just a productivity problem because it changes the reliability of safety decisions in real time. When one person must switch between 3 critical tasks within minutes, the visible output may continue, although the quality of attention, memory, and verification drops before any incident appears in TRIR or DART.

HSE identifies demands as 1 of the 6 Management Standards for work-related stress, alongside control, support, relationships, role, and change. That matters because multitasking is often a demand problem disguised as a performance style, especially in plants where the best supervisors become the default owners of every urgent exception.

Across 25+ years leading EHS at multinationals, Andreza Araujo has observed that high-performing teams often normalize overload first in the most competent people. The trap is subtle: the worker who can handle everything becomes proof that the job is manageable, even though the job has been quietly redesigned around an exceptional person.

HR and EHS should map where simultaneous demands appear in the day, not only how many tasks appear on the job description. A useful first pass is to review the first 2 hours of the shift, the last 45 minutes before handover, and every moment where a person signs a permit while handling production escalation.

2. Does training solve attention overload?

Training does not solve attention overload when the job still requires simultaneous verification, communication, and execution. A 60-minute course can explain attention limits, but it cannot protect a maintenance planner whose calendar has 9 meetings, 14 urgent messages, and 3 critical isolation reviews in the same morning.

HSE explains its Management Standards through work design factors, not through personal resilience slogans. That distinction matters because a training-only response often tells workers to cope better with a risk that leadership created through staffing, planning, and escalation design.

In more than 250 cultural transformation projects supported by Andreza Araujo's team, the more useful question is rarely "Did people receive training?" The stronger question is whether the work system gives people the time, authority, and sequencing needed to apply what the training asks them to do.

For a practical control, separate high-attention tasks from interruption-heavy windows. Permit approval, LOTO verification, critical-control checks, and post-incident interviews should have protected time blocks, because these tasks depend on deliberate attention rather than task volume.

3. Can the best supervisor safely handle everything?

The best supervisor is often the first person harmed by multitasking risk because competence attracts more interruptions. When one field leader becomes the informal hub for production, people issues, contractor questions, and safety verification, the organization creates a single human bottleneck with no redundancy.

This is where job demands and safety culture meet. A plant can have ISO 45001 documentation, toolbox talks, and a mature reporting process while still forcing one supervisor to act as planner, mediator, auditor, coach, and emergency dispatcher.

During the PepsiCo South America tenure, where the accident ratio fell 50% in 6 months, Andreza Araujo learned that visible leadership depends on operating rhythm, not heroic availability. Leadership that is always reachable may feel supportive, although it often means the operation has no disciplined escalation path.

EHS managers should test this by asking a simple field question: who absorbs the interruption when 2 urgent issues arrive during a critical lift, confined-space entry, or energized-work decision? If the answer is always the same supervisor, the risk control is a person, not a system.

4. Is multitasking a worker habit rather than a design flaw?

Multitasking can look like a worker habit because the behavior is visible, while the design flaw is hidden upstream. The worker checking a phone during a field task may be blamed, although the trigger may be a scheduling system, supervisor escalation pattern, or customer demand that rewards instant response.

EU-OSHA describes psychosocial risks and mental health as connected to how work is organized and managed. That wording is important for safety teams because it moves the investigation from individual discipline toward controls such as staffing, task sequencing, decision rights, and interruption rules.

Andreza Araujo's Portuguese title A Ilusao da Conformidade, "The Illusion of Compliance", is useful here because multitasking often survives behind compliant documents. The procedure says one task at a time, but the operating cadence tells people that immediate response, speed, and availability are the real performance currency.

A better audit looks for contradiction. Compare the written role with the calendar, radio traffic, chat volume, permit queue, and number of parallel approvals requested in 1 shift. When those artifacts disagree, the culture is in the artifacts, not in the policy.

5. Does multitasking only affect office work?

Multitasking affects field work whenever attention must move between physical hazard control and digital, verbal, or managerial demand. In a 320-employee industrial site, the risk may appear as a forklift operator responding to radio calls, a maintenance lead approving isolation while handling a contractor dispute, or an EHS technician documenting a near miss beside live traffic.

The mistake is to treat psychosocial risk as an HR-only topic. In occupational safety, multitasking can weaken risk register quality, pre-task risk assessment, Stop-Work Authority, and critical-control verification because each of these processes depends on attention at the exact moment the operation is trying to move faster.

Across 30+ countries and 250+ companies, Andreza has seen that the language of mental workload changes by culture, but the mechanism is consistent. People rarely say, "I am overloaded." They say, "We are in peak season," "the client is pushing," or "this is how this site works."

Supervisors can start with 3 field controls: no phone or radio escalation during critical verification, no permit signing while walking, and no simultaneous coaching and discipline conversation. These rules sound small, but they protect the moments in which attention is the barrier.

6. What should HR and EHS measure instead?

HR and EHS should measure multitasking risk through work-design evidence rather than self-reported busyness alone. A useful dashboard combines workload exposure, interruption frequency, protected-time compliance, overtime concentration, incident precursor timing, and the number of critical decisions made during high-demand windows.

WHO defines burnout in ICD-11 as an occupational phenomenon resulting from chronic workplace stress that has not been successfully managed. WHO explains this classification carefully, and it gives HR a reason to connect mental workload with prevention rather than treating exhaustion as a wellness campaign theme.

5 indicators deserve monthly review: tasks requiring protected attention, interruptions during those tasks, overtime by role, near misses during handover or peak demand, and supervisor escalation volume. This is not a replacement for psychosocial surveys, since it gives the survey operational teeth.

Link this dashboard to existing safety metrics. If observation quality, near-miss reporting, and control verification all fall during peak workload periods, the issue is not motivation. It is a predictable pattern in which workload risk planning should change before the next serious precursor appears.

Multitasking myths vs work-design controls

The comparison below separates a common belief from the control that actually reduces multitasking risk in safety critical work. It works best as a 30-day review tool for HR, EHS, operations, and line leaders.

What should change in the next 30 days?

The next 30 days should produce one visible change in operating rhythm, not another awareness campaign. Pick 1 high-risk role, map the 10 most frequent interruptions, protect the 3 tasks where attention is a safety barrier, and review whether supervisors can say no to noncritical escalation during those windows.

This is also where role clarity matters. When people do not know who decides, who stops, who approves, and who escalates, multitasking expands because every unclear boundary becomes another message, meeting, or interruption.

Each month without a multitasking review leaves the operation depending on memory, personal stamina, and informal heroics, while ISO 45003 and HSE-style psychosocial risk expectations move the market toward documented work-design controls.

Andreza Araujo's work keeps returning to the same practical thesis: safety is about coming home, and coming home depends on designing work so people can pay attention when attention is the control.

Conclusion

Multitasking risk is not a weakness in busy workers, because it is a design signal that exposes how the organization sequences work, protects attention, and chooses between speed and control.
