When something frightening happens at work - a robbery, a serious accident, a sudden death, an act of violence - the effects ripple through the whole team, not just those directly involved. Knowing how to respond well can make a real difference to recovery.

What it is

A critical incident is a sudden, distressing event that overwhelms a person or team's usual ability to cope. In the workplace, this could include armed robbery, a workplace accident, a colleague's death, an assault, or witnessing a traumatic event on the job. Critical-incident stress refers to the range of emotional, physical and behavioural reactions that follow - even for people who were not directly harmed but witnessed or heard about the event. It is a normal response to an abnormal event, and most people recover well with the right support in the days and weeks that follow.

Signs to notice

Shock, disbelief or numbness in the immediate aftermath
Difficulty concentrating or returning to normal tasks
Anxiety, jumpiness or hypervigilance in the workplace
Avoidance of the location or reminders of the incident
Sleep disturbance, irritability or tearfulness
Team tension, blame, or withdrawal from colleagues

What helps

Activate your organisation's critical-incident response plan promptly, including informing affected staff calmly and factually.
Give people accurate information as soon as possible - uncertainty tends to increase distress.
Allow those affected time and space, rather than expecting an immediate return to full productivity.
Encourage colleagues to check in on each other without pressuring anyone to talk before they are ready.
Offer practical support, such as adjusted duties or leave, alongside emotional support.
Bring in professional support early rather than waiting to see if people "get over it" on their own.

When to reach out for help

Managers should arrange professional support for any team affected by a critical incident as a matter of course, not only if someone asks. Individuals should seek support if they notice ongoing distress, avoidance, or difficulty functioning beyond a couple of weeks. Sooner is better than later - early support after a critical incident is linked to better recovery.
