Mental Health, Absence and Sustainable Return to Work in Safety-Critical Industries

Mental Health, Absence and Sustainable Return to Work in Safety-Critical Industries

Across logistics, haulage, transport, engineering, prisons and security environments, workforce mental health is becoming a strategic operational issue. Organisations operating in safety-critical environments are increasingly recognising that mental health is not only a wellbeing issue but is directly linked to absence levels, operational continuity, safety outcomes and organisational risk.

Mental health conditions are now a significant driver of sickness absence across the UK workforce, and some sectors are disproportionately affected. For HR and business leaders, it is important to think about how to provide interventions that create sustainable recovery rather than short-term crisis management.

Mental Health as a Driver of Workplace Absence

Mental health conditions are now one of the most common causes of illness in the UK. Estimates suggest that around 875,000 workers experience work-related stress, depression or anxiety each year, resulting in approximately 17.1 million working days lost annually (Health and Safety Executive, 2023).

In safety-critical sectors such as transport and logistics, the impact is particularly evident. Industry data shows that:

• The transport and logistics sector reports higher levels of absenteeism compared with many other private-sector industries (Mates in Mind, 2023).

• Sickness absence rates in transport roles have exceeded national averages, reflecting operational pressures and working conditions associated with these roles (Chartered Institute of Logistics and Transport, 2022).

• In rail environments, mental health conditions account for a significant proportion of absence, with approximately 14% of absences linked to mental health causes (Rail Safety and Standards Board, 2022).

These findings reflect working environments characterised by irregular shifts, safety responsibility, exposure to incidents, isolation, and sustained performance pressure. Similar patterns are observed in prisons, security and engineering environments, where employees are required to maintain vigilance and decision-making under pressure.

Absence figures alone may underestimate the scale of the issue. Evidence suggests that presenteeism, employees attending work while experiencing poor mental health, remains common within safety-critical sectors, creating hidden productivity and safety risks (Rail Industry Association, 2021).

Why Symptoms Return Without Proper Treatment

A common organisational misconception is that once an employee returns to work, the underlying problem has been resolved. In practice, many mental health conditions are recurrent in nature or where left without adequate treatment can have longstanding impacts on functioning. This requires evidence-based psychotherapy so as to address underlying issues and responses, and build skills and strategies to support a sustained return to their regular duties.

Stress, anxiety, depression and trauma-related conditions involve behavioural and cognitive patterns that can become self-reinforcing. Without evidence-based intervention, individuals may develop avoidance behaviours, maladaptive coping strategies or heightened stress responses that re-emerge when workplace pressures return.

Evidence-based psychotherapies, including cognitive behavioural approaches, have consistently demonstrated effectiveness in reducing symptoms and improving functional outcomes by helping individuals understand their condition, identify triggers and develop practical coping strategies (National Institute for Health and Care Excellence, 2022). The aim is not only symptom reduction but sustained recovery and improved occupational functioning.

For employers, this distinction is significant. Recovery without skills development frequently results in recurring absence, whereas recovery supported by psychological tools enables employees to maintain performance and wellbeing over time.

Moving Beyond Crisis Management: A Two-Stage Model of Support

In high-risk, safety-critical industries, effective mental health support should be understood as a pathway rather than a single intervention.

1. Acute Psychological Treatment: Stabilisation and Recovery

When employees are absent or at risk of absence due to mental health conditions, early access to specialist psychological treatment enables:

• Clinical assessment and formulation

• Evidence-based therapeutic intervention

• Reduction of acute symptoms

• Structured preparation for return to work

Early psychological intervention has been shown to reduce the duration of sickness absence and improve return-to-work outcomes in employees experiencing common mental health disorders (OECD, 2021).

2. Condition Management Pathway: Sustaining Progress Long Term

The second phase is ongoing condition management. A structured Condition Management Pathway enables employees to:

• Recognise early warning signs of relapse

• Maintain therapeutic strategies learned during treatment

• Manage workplace stressors proactively

• Sustain long-term work participation

This approach reflects a necessary shift in thinking: mental health support is not solely about managing crises, but about maintaining stability and resilience over time.

For organisations, this leads to fewer repeated absences, improved workforce planning and greater confidence in sustainable return-to-work processes.

The Business Case: Duty of Care, Risk Reduction and Sustainable Return to Work

Alongside wellbeing outcomes, there is a clear organisational and financial rationale for structured psychological support. Poor mental health is estimated to cost UK employers between £42 billion and £45 billion annually through absence, presenteeism and staff turnover (Deloitte, 2022).

In safety-critical environments, unmanaged mental health conditions may also increase operational risk through reduced concentration, impaired decision-making and higher likelihood of incidents. Providing access to evidence-based treatment and long-term condition management demonstrates that organisations have taken reasonable and proactive steps to support employee recovery, strengthening duty-of-care obligations and reducing exposure to employment disputes or litigation.

Most importantly, it supports genuinely sustainable return to work, where employees return not only able to work, but manage their mental health in the long-term.

A Strategic Shift for Safety-Critical Organisations

For HR and operational leaders in logistics, transport, engineering, prisons and security, mental health management must move beyond reactive support models.

Organisations achieving the strongest outcomes increasingly adopt a continuum of care:

• Early identification

• Acute psychological treatment

• Structured return-to-work planning

• Long-term condition management

Using these structures, once mental health is professionally supported, the operational health of the business is safeguarded. When employees understand their condition and have the tools to manage it, absence reduces, retention improves and safety performance strengthens.

In safety-critical industries, sustainable recovery is not only beneficial for employees it is an essential part of organisational resilience.
