A serious accident happens at work. An employee dies unexpectedly. Staff witness violence, a suicide attempt, an assault, or a frightening medical emergency. Once the immediate crisis is over, leadership is left with a much less familiar question: What do we do for everyone who just experienced this?

Organizations are generally much better prepared for the emergency itself than for its psychological aftermath. There may be procedures for calling 911, notifying leadership, completing incident reports, and communicating with families. Supporting the people who witnessed, responded to, or were otherwise affected by the event can feel considerably less clear.

The answer is not to assume everyone is traumatized. It is also not to send a reassuring email, offer the Employee Assistance Program number, and hope everyone is back to normal by Monday. A thoughtful critical-incident response falls somewhere between those two extremes.

Start With Safety, Information, and Basic Human Needs

Immediately after a traumatic event, the first priorities are practical. People need physical safety, accurate information about what happened, access to the people they rely on, and some understanding of what will happen next. When information is unavailable, saying that clearly is generally better than allowing rumors to fill the vacuum.

Employees may also need very ordinary things: transportation home, someone to contact a family member, time away from work, help retrieving belongings, or permission not to walk immediately back into the location where something terrible just happened. Trauma-informed care is not always complicated. Sometimes it begins with recognizing that a person who just performed CPR on a coworker probably does not need to finish their spreadsheet before leaving.

This type of immediate, practical support is consistent with principles of Psychological First Aid, which emphasizes humane, supportive, practical assistance after serious crisis events without pressuring people to discuss what happened.

Leadership should also be thoughtful about how much information is shared. Employees may need enough information to understand what occurred and what the organization is doing, while the privacy of the person involved and their family still matters.

Expect Different Reactions to the Same Event

A shared event does not create a shared psychological response. Ten employees can witness the same incident and walk away having experienced it very differently.

One person may feel shaken for several hours and then gradually recover. Another may replay a particular image repeatedly, while someone else becomes irritable, numb, distracted, or unusually vigilant. A person who seemed remarkably calm during the emergency may struggle several days later when their nervous system finally has room to react.

Previous experiences, proximity to the event, relationship with the person involved, perceived helplessness, and what someone saw or heard can all influence the response. The employee who provided first aid may have a very different experience from the employee who witnessed the event from across the room.

That variation is normal. Organizations should avoid creating an expectation that there is one correct way to respond.

Strong Reactions Don't Automatically Mean PTSD

Disturbed sleep, intrusive thoughts, nightmares, difficulty concentrating, anxiety, increased startle responses, emotional numbness, and irritability can occur following a frightening experience. These reactions can be distressing without necessarily indicating that someone has developed Post-Traumatic Stress Disorder.

In fact, many people recover naturally following trauma. NICE clinical guidelines for PTSD recommend active monitoring for people experiencing subthreshold PTSD symptoms during the first month following a traumatic event rather than assuming everyone who has been exposed requires immediate trauma treatment.

That distinction matters. We don't want to pathologize normal responses to an abnormal event. At the same time, natural recovery should not become an excuse for ignoring people who are clearly struggling.

Some employees will need additional support, particularly when symptoms are severe, persistent, worsening, or interfering with daily functioning. Others may benefit from information, flexibility, social support, and time. More information about trauma reactions and treatment is available on our Trauma, Chronic Stress & PTSD page.

Support People Without Forcing Them to Process

After something terrible happens, gathering everyone together to talk about it can sound like the compassionate thing to do. The problem is that support and trauma processing are not the same thing.

Organizations can acknowledge what happened, provide accurate information, explain common reactions, make practical accommodations, and offer professional resources. None of those things requires an employee to publicly describe what they saw, how frightened they were, or what they are feeling now.

There is also an important distinction around the word debriefing. First responders, law enforcement agencies, healthcare teams, and other organizations may use operational debriefings, after-action reviews, peer-support programs, or other post-incident supports. These are not automatically the same thing as psychologically focused trauma debriefing.

The concern identified in PTSD treatment guidelines  specifically involves psychologically focused debriefing used for the prevention or treatment of PTSD. It does not mean organizations should eliminate operational reviews, appropriate post-incident communication, or peer support.

We'll explore these distinctions more fully in a separate article on debriefing, peer support, Psychological First Aid, and Group EMDR after critical incidents.

Give Employees Choices

Trauma frequently involves a loss of control. A thoughtful organizational response should avoid unnecessarily taking more control away.

Some employees will want to talk. Others will not. Some may want professional support immediately, while others may prefer to wait and see how they feel over the next several days or weeks.

Employees should be able to understand what type of support is being offered and decide whether they want to participate whenever possible. Declining a group intervention should not become evidence that someone is "not coping" or unwilling to support the team.

If therapy is being offered, employees should also understand what the service involves, what confidentiality means, any limits to confidentiality, and whether any information will be shared with the organization.

Be Clear About the Employer's Role

When an organization brings in a therapist following a critical incident, there may be multiple relationships involved. The organization may arrange or pay for services, while individual employees participate in clinical care.

Employees should know what service is being offered and what role the organization has in that service. They should also know what information remains private and whether anything will be communicated back to their employer.

This becomes especially important when services are offered in a group setting. Group members can agree to respect one another's privacy, but confidentiality among participants cannot be guaranteed in exactly the same way as confidentiality between an individual client and therapist.

Clear expectations help employees make an informed choice about participating.

Where Might Group EMDR Fit?

When several people have been affected by the same traumatic incident, Group EMDR may be one treatment option. It is not the same as gathering employees into a room and asking everyone to tell the story of what happened.

One approach used in Group EMDR is the Group Traumatic Episode Protocol, or G-TEP. Developed by EMDR clinicians Elan Shapiro and Brurit Laub, G-TEP grew out of the Recent Traumatic Episode Protocol (R-TEP) and was designed as an early EMDR intervention that can be delivered in a group format.

G-TEP provides a structured way for participants to work with their own experience while using EMDR-based strategies, including bilateral stimulation. Rather than taking turns recounting traumatic experiences to the group, participants can work more privately with words, drawings, symbols, or other representations of what they experienced.

That privacy is an important distinction. Employees may have experienced the same event without being affected by the same part of it. Each person can work with their own experience without needing to disclose every detail to coworkers.

When Else Might G-TEP Be Helpful?

Although we're talking specifically about workplace trauma here, G-TEP isn't limited to coworkers who experienced the same critical incident. It can also be used with groups affected by recent, ongoing, or related traumatic experiences—even when everyone did not experience the exact same event.

Situations in which G-TEP may be helpful include:

• Natural disasters, including wildfires, floods, hurricanes, tornadoes, earthquakes, or displacement from homes and communities.

• Community violence, including mass shootings, neighborhood violence, or other events affecting a community.

• School or university incidents, such as a student or staff death, suicide, violence, serious accident, or threat affecting students, faculty, or staff.

• Healthcare-related trauma, including difficult patient deaths, medical emergencies, traumatic injuries, repeated high-acuity situations, or particularly disturbing cases affecting healthcare teams.

• First-responder exposure, including difficult calls or cumulative traumatic experiences affecting firefighters, paramedics, law enforcement, dispatchers, emergency personnel, and rescue workers.

• Military and veteran experiences, including combat, deployment-related trauma, disasters, and other traumatic operational experiences.

• Sudden or traumatic loss, including suicide, homicide, unexpected death, or circumstances in which grief and traumatic exposure overlap.

• Serious accidents, including motor vehicle crashes, industrial or construction accidents, explosions, and other incidents involving multiple people.

• Interpersonal violence, including groups of survivors of domestic violence, sexual assault, trafficking, or related experiences.

• War, displacement, or forced migration, including people exposed to persecution, conflict, dangerous migration, or loss of community.

• Repeated occupational exposure to traumatic material, which can affect victim advocates, child-protection workers, healthcare providers, therapists, forensic professionals, journalists, and others whose work repeatedly brings them into contact with disturbing events or material.

People also don't necessarily have to share the exact same experience. A group of healthcare professionals might each be working through different difficult cases, while first responders may be affected by separate incidents encountered over the course of their careers.

In other words, the common denominator doesn't always have to be what happened. Sometimes it is the shared experience of carrying the effects of difficult or traumatic events.

Is Group EMDR Right for Everyone?

Not necessarily—and that is okay. Some people may benefit from Group EMDR, while others may prefer or benefit more from individual therapy. Still others may find that their reactions settle naturally with time, support, and a return to safety and routine.

Research on Group EMDR is encouraging. A systematic review of Group EMDR interventions included 22 studies with 1,739 adults and children and found that Group EMDR protocols may improve PTSD, depression, anxiety, and other mental-health outcomes. The researchers also noted limitations in the available research and the need for continued study.

The important point is that experiencing a traumatic event does not automatically mean someone needs therapy. When additional support is needed, however, Group EMDR offers another way for people to work through traumatic experiences without requiring them to publicly tell the entire story of what happened.

Don't Forget the People Who Took Care of Everyone Else

Following a workplace emergency, some of the most affected people may not be immediately obvious. Managers, HR professionals, supervisors, healthcare workers, first responders, and employees who stepped in during the crisis may quickly move into problem-solving mode.

They contact families. They communicate with staff. They complete reports, answer questions, cover shifts, and make sure everyone else is okay.

Being competent during an emergency does not make someone immune to its effects. Leadership and response personnel should have access to support too.

Sometimes the person holding everything together is simply the person whose reaction hasn't arrived yet.

Have a Psychological Critical-Incident Plan Before You Need One

Most organizations would never wait for a fire to decide where the exits should be. Psychological critical-incident response deserves some advance planning too.

A plan can identify who leadership contacts following a traumatic event, how employees will receive accurate information, what immediate support can be offered, and how additional mental-health resources can be accessed. It can also help leadership think ahead about practical questions that are much harder to answer in the middle of a crisis.

Organizations can identify qualified trauma professionals in advance rather than searching for one after something has already happened. Depending on the circumstances, post-incident support might include practical assistance, Psychological First Aid, psychoeducation, peer support, individual services, or Group EMDR.

The best response is rarely one intervention applied to everybody.

The Takeaway

After a workplace trauma, employees need support without being told how they are supposed to feel. Some people will recover naturally with time, safety, information, and connection. Others may continue to experience distress and benefit from more specialized trauma treatment.

Organizations can help by communicating clearly, allowing reasonable flexibility, protecting privacy, avoiding forced trauma processing, and making appropriate support available. Just as importantly, they can recognize that different people may need different things after the same event.

Group EMDR can be one part of that response when it fits the needs of the people involved. It offers a structured way to address traumatic experiences while allowing participants to keep much of what they are processing private.
