Can You Dismiss an Employee for Being Drunk at Work?

An employee can be dismissed for being drunk at work, but employers cannot automatically terminate someone simply because alcohol is involved.

Whether a dismissal is lawful depends on the circumstances. Employers should consider factors such as workplace safety, the employee’s role, prior disciplinary history, company policies, and whether alcohol dependence may qualify as a disability requiring accommodation under human rights legislation.

If you have been disciplined or fired after allegations of intoxication at work, not every alcohol-related incident will justify dismissal. In some cases, employers may have grounds for discipline or termination. In others, the employee may have legal rights that were overlooked.

What to Do if an Employee Comes to Work Drunk?

When an employer believes an employee is intoxicated at work, the first priority is workplace safety.

Employers have a responsibility to maintain a safe work environment. If an employee appears impaired, they may be removed from duties temporarily while the situation is assessed. This is particularly common in safety-sensitive workplaces such as construction sites, manufacturing facilities, transportation services, healthcare settings, and jobs involving heavy machinery.

However, employers should not assume intoxication without evidence. Symptoms that appear to be alcohol-related can sometimes be caused by fatigue, illness, prescription medications, or other medical conditions. A fair employer should gather information before deciding what happened and whether discipline is warranted.

That process often includes interviews, reviewing available evidence, and documenting observations. A proper investigation is important because decisions based on assumptions can expose employers to legal claims. For employees, this means that an allegation of intoxication should not automatically be treated as proof of misconduct. Employers should assess the facts before deciding whether discipline or dismissal is appropriate.

Is Alcoholism Considered a Disability?

Yes.

Alcohol dependence can be recognized as a disability under the Ontario Human Rights Code.

This distinction is significant because employers have legal obligations when workplace misconduct may be connected to a disability. In many situations, employers have a duty to accommodate employees with disabilities up to the point of undue hardship.

Accommodation does not mean employees can never be disciplined for alcohol-related conduct. Employees are still expected to perform their jobs safely and follow workplace rules. However, employers cannot simply ignore the possibility that addiction may be contributing to the situation.

If an employee has disclosed an alcohol dependency, requested assistance, or shown signs that a substance use disorder may be involved, employers may be required to consider accommodation before moving directly to dismissal.

Employees who believe their employer failed to consider accommodation obligations may have legal protections under human rights legislation.

The relationship between addiction, workplace misconduct, and termination has been considered repeatedly by Canadian courts. Employers are generally expected to distinguish between misconduct and conduct that may be connected to a disability, while also balancing workplace safety and performance concerns. A Supreme Court decision involving addiction and termination illustrates how addiction, misconduct, and accommodation obligations can overlap in the workplace.

Does Being Drunk at Work Always Justify Dismissal?

No. Even where an employee has consumed alcohol before or during work, dismissal is not always justified.

Courts assess workplace misconduct in context. Rather than focusing on a single incident in isolation, they consider the overall employment relationship and the seriousness of the conduct.

Factors that may be considered include the employee’s role, length of service, disciplinary history, workplace policies, the level of impairment, whether anyone’s safety was affected, and whether the incident was isolated or part of a larger pattern of misconduct.

Courts also recognize that not all workplace roles carry the same level of risk. An employee working in a safety-sensitive position may face greater scrutiny than someone whose duties do not create significant safety concerns. The circumstances surrounding the incident can also matter. A single lapse in judgment by a long-service employee with no disciplinary history may be viewed differently than repeated incidents involving the same conduct. Employers are generally expected to consider the full context before concluding that dismissal is justified.

In some situations, employers may argue that the conduct amounts to just cause. Just cause is one of the highest standards in employment law and can allow an employer to dismiss an employee without notice or severance obligations. However, establishing just cause is often more difficult than employers assume. Courts assess factors such as the seriousness of the misconduct, the employee’s role, their disciplinary history, and the overall employment relationship when determining whether discipline and just cause termination are legally justified.

Employers must also remain mindful of potential accommodation obligations. If alcohol dependence or another disability is involved, human rights considerations may affect whether dismissal is appropriate. Similar issues can arise when an employee is dealing with other medical conditions that impact their ability to work. Questions about whether an employee can be fired while on short-term disability often involve many of the same accommodation principles.

The fact that alcohol was involved does not automatically determine whether a dismissal was lawful. Every case depends on its specific facts.

In some situations, employers may decide that discipline short of dismissal is more appropriate. Depending on the circumstances, this could include a warning, suspension, mandatory treatment requirements, or other corrective measures. The appropriate response will depend on the severity of the conduct and whether the employment relationship can reasonably continue.

Final Thoughts

An employer may be able to dismiss an employee for being drunk at work, but termination is not automatic.

Before deciding whether dismissal is justified, employers are generally expected to investigate the circumstances, assess workplace safety concerns, consider the employee’s history, and determine whether any accommodation obligations apply. Employees who have been dismissed following allegations of intoxication should not assume that the employer acted lawfully simply because alcohol was involved.

When addiction, disability, procedural fairness, or just cause issues are involved, determining whether a dismissal was lawful can become far more complicated.
