Work accident under the influence of alcohol or drugs: what are the employer's obligations?

Work accident under the influence of drugs or alcohol: what are the consequences for the employer and the employee?

When an employee suffers an accident during the performance of their duties, it is generally classified as a work accident. This classification has consequences both for the handling of the accident (by Social Security and the employer) and for the responsibility of each party. But what happens if the employee is under the influence of drugs or alcohol at the time of the accident? Is the accident still classified as a work accident? In this article, we will review the definition of a work accident and the applicable rules, before highlighting the importance for the employer to implement supportive screening campaigns and appropriate training to prevent these situations and to protect both the company and the employees.

1. Definition of a work accident

In France, the Social Security Code (article L. 411-1) defines a work accident as any accident occurring, regardless of the cause, by reason of or during work to any employee or person working in any capacity or location for one or more employers.

The criteria for an accident to be recognized as a work accident are therefore:

• An accidental event occurring on a specific date;
• During or on the occasion of the exercise of professional activity.

The employer remains responsible for the safety and health of their employees. They must implement the necessary prevention measures (information, training, verification of employee fitness, etc.).

2. Accident under the influence of alcohol or drugs: the presumption of imputability

The legislation provides a presumption of imputability according to which an accident occurring at the workplace and during working hours is, in principle, presumed to be a work accident. This principle is very protective for the employee. To overturn this presumption, the employer or the primary health insurance fund must prove that the accident has a cause completely unrelated to work.

Thus, an employee under the influence of alcohol or drugs can be the victim of an accident during working hours or on the route related to their mission (for example, a driver making a delivery route). This alone is not enough to strip the accident of its status as a work accident.

Practical case from the Court of Cassation (Social Chamber, October 22, 1974)

In a ruling (
Cass. Soc., October 22, 1974, no. 73-12.702
), the High Court confirmed that an accident under the influence of alcohol does not automatically deprive the employee of the protection linked to the classification of a work accident. Relying on the presumption of imputability, the Court of Cassation ruled that even in the case of employee fault (driving under the influence), the accident can retain its professional nature, unless the employer can prove that this fault was the sole and exclusive cause of the accident and that it was completely unrelated to work.

Example from the ruling: A driver caused an accident while driving under the influence of alcohol. The Court considered that this circumstance was not sufficient to exclude the classification as a work accident, because the accident occurred “by reason of or on the occasion of work”; in other words, during the time and at the place of the mission assigned by the employer.

3. Consequences for the employer and the employee

3.1. Recognition of the work accident

• If the accident is classified as a work accident, social charges and coverage will then be handled according to Social Security rules: increased daily allowances for the employee, possible pension in case of disability, etc.
• The employer may see their work accident insurance contribution increase depending on the severity of the accident and their claim rate.

3.2. Employer’s responsibility

• The employer has a safety obligation. They must prevent risky behaviors (alcohol, drugs, fatigue, etc.) through appropriate prevention actions.
• They may initiate, if necessary, a disciplinary procedure against the offending employee, insofar as the consumption of alcohol or drugs constitutes serious misconduct and may threaten the safety of people and property. However, the accident remains, by default, the employer’s responsibility if the conditions of time and place are met.

3.3. Sanctions for the employee

• On the criminal level, if the employee is found guilty of offenses (for example, driving under the influence), they may be sanctioned (license suspension, fine, etc.).
• On the disciplinary level, they face sanctions up to dismissal for serious misconduct if the fault endangers the safety of the company or third parties.

4. Prevent to act better: the importance of supportive screening campaigns and appropriate training

The consumption of alcohol or drugs at work presents significant risks to the health and safety of employees, as well as to the company and third parties. To avoid serious accidents and complex legal situations, the employer has every interest in strengthening prevention.

4.1. Deploy an appropriate prevention policy

• Internal regulations: The employer can precisely define the rules regarding alcohol and drug consumption at work, as well as the sanctions incurred.
• Information and awareness: Implement information campaigns on the dangers of psychoactive substances, especially for high-risk positions (drivers, machine operators, etc.).
• Appropriate training: Offer specific training for managers and employees in sensitive positions. These sessions can include detecting warning signs and best practices to adopt when dealing with a colleague in difficulty.

4.2. Implement supportive screenings

• Regular and targeted screenings: For so-called “sensitive” positions (drivers, equipment operators, workers at height…), screening can be provided for in the internal regulations, while respecting employee rights.
• Our screening tests: We offer reliable and easy-to-implement screening solutions within your organization. This approach, focused on support, aims to prevent accidents rather than punish.
• Support in case of a positive result: The goal is not to “trap” the employee but to avoid accidents and ensure everyone’s safety. In case of a positive test, we recommend establishing constructive dialogue, identifying support solutions (psychological help, regular follow-up, etc.), and ensuring the safe reintegration of the person concerned.

4.3. Our training and prevention programs

• Employee training: We offer targeted programs to inform employees about the effects of alcohol and drugs and to provide them with the keys to responsible consumption, or even abstinence, in the workplace.
• Manager training: Raising awareness among supervisors enables them to adopt the right approach to detect, communicate, and act effectively while respecting confidentiality and the dignity of colleagues.
• Monitoring and evaluation plan: Our training includes monitoring tools to measure the effectiveness of prevention campaigns, adjust actions, and sustain best practices within the company.

5. Conclusion

A work accident under the influence of drugs or alcohol can still be recognized as such, unless the employer proves that the accident is completely “unrelated to work.” The employer’s approach must therefore be preventive and supportive to limit risky behaviors and protect the physical and mental integrity of employees.

In this respect, the implementation of alcohol and drug screening campaigns, combined with information actions and appropriate training, is an essential lever to reduce risks. Beyond avoiding complex and costly disputes, these prevention and screening actions contribute to a climate of trust and safety within the company, in the interest of all: employer, employees, and third parties who may suffer the consequences of an accident under influence.
