Depression at work: 12 signs that your colleague (or you) is not doing well
Depression manifests differently at the office than at home. Learning to spot the subtle signals from a manager, HR, or colleague — and knowing how to react without awkwardness or indiscretion.
Why depression at the office is hard to see
In the workplace, social and professional codes mask the classic emotional symptoms of depression. One does not cry in meetings, one does not say "I'm not doing well" to a client, one does not stay in bed since one must come in. This pressure to perform produces a well-documented phenomenon: so-called "smiling" depression or presenteeism, where the person continues to function outwardly while experiencing great internal suffering.
The other reason for late detection is cultural prejudices. Recognizing that one is depressed in a professional environment is still seen as a career risk, whereas the survey by the National Observatory of Quality of Life at Work shows the opposite: employees who seek help and benefit from appropriate leave return more productive and stay longer in the company than those who burn out in silence.
The twelve signals that should raise alarms at work
Visible behavior side
1. A sudden drop in work quality
Not a gradual decline due to a difficult project, but a clear deviation from the usual level: unusual errors, forgetfulness, deliverables that require multiple revisions. This is not a lack of competence; it is the direct effect of depressive cognitive disorders.
2. Increasing delays and absences
Arrivals becoming increasingly late, repeated short breaks for vague reasons, early departures. The person is simply struggling to cross the company's threshold.
3. Withdrawal from collective moments
No more shared coffee breaks, no more lunches with the team, systematic refusal of afterworks or seminars. The person isolates themselves in their office or behind their screen.
4. Unusual slowness or agitation
Either a noticeable slowdown (gestures, speech, decision-making), or conversely, anxious restlessness, an inability to stay in one place, back and forth between offices without a clear purpose.
5. Irritability and emerging conflicts
Particularly among men, depression can manifest as increased intolerance: sharp remarks, disproportionate annoyance, conflicts with colleagues with whom relations were previously good.
6. Prolonged presenteeism
Staying late without making real progress, working weekends without tangible results, accumulating hours without effectiveness. This behavior often reflects anxiety about not being able to cope, which paralyzes instead of producing.
Speech and emotion side
7. Disappropriation of successes
"I was lucky," "it would have worked anyway," "it's nothing." This tendency to minimize every success, where the person previously accepted positive feedback, is a marker of depressive devaluation.
8. Worrying phrases
"I can't take it anymore," "it doesn't make sense," "others would do better without me." These statements, even if said in a joking tone, should be taken seriously. They often signal a suffering that seeks to be expressed without daring to.
9. Loss of professional momentum
No more proposals in meetings, no new ideas, no initiative taken. The person does the minimum without projection. This is professional anhedonia, equivalent at the office to the loss of interest that characterizes depression.
Physical side
10. Visible and constant fatigue
Dark circles, dull complexion, slumped posture, micro-naps in meetings. The person arrives already exhausted in the morning, despite apparently sufficient hours of sleep.
11. Repeated somatic complaints
Headaches, back pain, digestive issues, dizziness that appear or intensify. These physical complaints without an identified medical cause are often the expression of unspoken depression.
12. Changes in weight or appearance
Notable weight loss, or conversely, rapid gain. Neglect of previously cared-for aspects (clothing, hairstyle, hygiene). This does not necessarily indicate depression, but combined with other signals, it is a strong indicator.
| Observed signal | Often confused with | What should raise suspicion of depression |
|---|---|---|
| Drop in performance | Demotivation, laziness | Sudden appearance, contrast with usual level |
| Repeated delays | Lack of rigor | Previously punctual person, vague reasons |
| Irritability | Difficult character | Sharp change in temperament |
| Isolation | Personal preference | Gradual withdrawal, systematic refusal |
| Physical complaints | Hypochondria | Multiple, without identified organic cause |
| Dark phrases | Dark humor, fatalism | Recurring, without context that justifies them |
Recognizing signs in oneself
Spotting emerging depression in oneself is paradoxically more difficult than in others. Depression itself blurs the perception of what one is experiencing: fatigue is attributed to workload, irritability to lack of sleep, disinterest to boredom in the job. A few internal signals deserve attention.
If you cry for no clear reason in the office restroom, if you dread Sunday evenings to the point of feeling nauseous, if you count the hours until the end of the day without expecting anything from work, if your thoughts loop on your presumed failures instead of settling, then something exceeds mere professional fatigue. On DYNSEO, you can take an online self-questionnaire that will give you an objective benchmark on the intensity of your symptoms — without replacing a consultation, but as a first point of support.
How to talk about it — without awkwardness
For a manager or colleague
Addressing a colleague's suffering is a delicate exercise. Three simple principles avoid the most common mistakes. Do not wait to have "proof": your role is not to diagnose but to extend a hand. Choose a calm moment and place, never in open space or at the end of a meeting. Talk about what you observe, not what you assume: "I've noticed that you seem tired lately" rather than "You're depressed, aren't you?".
Avoid at all costs phrases that close the door: "pull yourself together," "there are worse things," "I'm tired too," "think positive." Prefer listening and availability: "if you need to talk, I'm here." A regular presence, even brief, is better than a long speech followed by silence.
For HR
The role of an HR department in response to signs of depression in an employee is not to diagnose or treat, but to guide and protect. Three levers exist: the occupational physician (consultation possible at the request of the employee, manager, or HR, under medical confidentiality), anonymous listening services offered by many companies (PsyaSanté, ProConsulte, Pros-Consulte depending on contracts), and possible adjustments via the Recognition of the Quality of Disabled Worker (RQTH) which includes mental disabilities.
For the employee themselves
If you recognize the signals in your daily life, the primary contact remains your general practitioner. They can prescribe a leave if necessary — no, it is not a weakness — and refer you to a psychiatrist or psychologist. The occupational physician is bound by medical confidentiality: they can adapt your position without revealing the diagnosis to your employer.
🎯 Suicidal thoughts: what to do
If a colleague expresses thoughts of death, even fleetingly, do not minimize it. Stay with them, listen without judging, do not leave them alone. The 3114 (national suicide prevention number, free, 24/7) also welcomes calls from concerned relatives. For immediate shelter, call 15 or psychiatric emergencies. You do not have to bear this responsibility alone.
The role of the company in prevention
Companies did not wait for legal obligations to take up the subject, but they have been gaining competence for five years. The law of August 2, 2021, strengthened their obligations regarding mental health, now integrated into the single risk assessment document. Effective prevention policies combine four dimensions.
First, raise awareness and train managers to detect weak signals. A trained manager spots issues twice as early as an untrained manager, and their interventions are better received. The DYNSEO online training, certified Qualiopi, addresses these issues in several courses dedicated to inclusion, mental health at work, and supporting employees in difficulty.
Next, structure the support: occupational health, external psychological support, disability reference, social mission. When these resources are visible, accessible, and confidential, they are used. When they are theoretical, they serve no one.
The third pillar is to adjust the actual workload. A work-related depression almost always has a prolonged period of unrecognized overload in its history. Regulating the workload is not an HR luxury; it is a public health measure in the workplace.
Finally, organize the return after a leave. The risk of relapse is highest in the first six months post-return. A gradual, supported return, with a possibly temporarily adjusted position, reduces the risk of relapse by a third according to data from the Health Insurance.
💡 Cognitive stimulation and returning to work
Cognitive disorders (concentration, working memory, decision-making) often persist for several weeks after mood stabilization. Maintaining stimulating brain activity without performance pressure — short, fun exercises with adjustable intensity — helps regain a sense of personal effectiveness. The JOE application offers exercises suited for this return phase.
What to remember
Depression at work takes specific forms that are not described by the classic image of sadness. It is seen in declining performance, in the withdrawal that sets in, in the multiplying physical complaints, in the dark phrases that tend to be minimized. As a manager, HR, or colleague, your role is not to treat — it is to identify, to dare to speak openly, and to guide towards the right resources. For the person concerned, recognizing what is happening and consulting does not shorten their career: it saves it.
Frequently asked questions
Can a manager address a colleague's depression without encroaching on their private life?
Yes, as long as they stay within observable professional aspects: work quality, deadlines, availability. Mentioning these facts, expressing concern, and directing towards the occupational health doctor falls within the managerial role. Diagnosing or questioning personal life does not.
Should HR be notified when suspecting a colleague's depression?
Orientation first goes through a direct exchange with the person. If they agree, you can accompany them to the occupational health doctor or HR. In case of emergency (suicidal thoughts, danger), notifying a resource becomes necessary even without their consent — confidentiality fades in the face of life-threatening risk.
How long does a leave for depression typically last?
According to data from the Health Insurance, the average duration of leave for a depressive episode is about 110 days, but with great variability: from a few weeks for mild depression to several months for a severe form. The return often occurs in a therapeutic part-time for 2 to 4 months.
Is work-related depression recognized as an occupational disease?
Not automatically, but it is possible. Since 2017, mental health conditions can be recognized as occupational diseases if the link to work is demonstrated and if the partial permanent incapacity exceeds 25%. The file goes through the Regional Committee for the recognition of occupational diseases.
Does remote work worsen depression?
It depends on the situations. Remote work reduces transport stress and offers flexibility, but it increases isolation and blurs the boundaries between professional and personal life, two risk factors for depression. Hybrid configurations, maintaining collective moments in person, yield the best results for mental health.
What to do if you suspect your own depression without wanting to stop working?
Consulting a general practitioner or psychologist does not require stopping work. Many people start therapy while continuing to work, sometimes with temporary adjustments (increased remote work, reduced workload). The important thing is to seek help before the situation deteriorates to the point of necessitating a leave.
How to support a colleague returning from leave for depression?
Reconnect normally, without overplaying concern or acting as if nothing happened. A simple phrase — "Glad to see you back, let me know if I can help you with the files" — is enough. Avoid questions about what they experienced unless they bring it up themselves.
Is a disability recognition for depression visible in the company?
No. The disability recognition does not mention the nature of the disability, and the employee is not obliged to inform their employer. If they do, it is to benefit from adjustments (equipment, hours, remote work). The medical diagnosis remains covered by the medical confidentiality of the occupational health doctor.
A subject that is played collectively
Depression at work is neither a fatality nor a strictly individual issue. It can be prevented when the company structures prevention, it can be identified when managers and colleagues know how to recognize the signals, and it can be treated when the person accesses medical and therapeutic resources. Everyone, in their place, can make a difference — without having to become an expert, just by keeping their eyes open and daring to say the right phrases at the right time.
