employer for harassment
If you are experiencing harassment from a co-worker, you may wonder, can you sue your employer for harassment? In many cases, the answer is yes—employers have a legal duty to maintain a safe and harassment-free workplace. Under the Ontario Human Rights Code and the Occupational Health and Safety Act (OHSA), employers are responsible for preventing and addressing workplace harassment, even when the harasser is a co-worker. If your employer fails to take action, you may have legal grounds to sue for damages.
Harassment from a co-worker can take many forms, including bullying, discrimination, and repeated hostile actions. If the harassment is based on protected characteristics—such as race, gender, age, disability, or sexual orientation—it violates the Ontario Human Rights Code. Even if the harassment is not linked to a protected characteristic, non-code-based workplace harassment, like intimidation or verbal abuse, still falls under the employer’s responsibility under the OHSA. If your employer is aware of the harassment and does not take appropriate steps to stop it, you may be entitled to legal action.
One legal ground to sue your employer is constructive dismissal. Constructive dismissal occurs when an employer breaches the terms of employment to the point where an employee feels forced to resign. If your employer ignores harassment complaints or fails to provide a safe work environment, it may create a toxic workplace—a common basis for a constructive dismissal claim. For example, if a co-worker consistently bullies you, and your employer takes no action despite being informed, you may have a valid case. However, in Ontario, Section 31 of the Workplace Safety and Insurance Act (WSIA) may bar claims related to mental stress caused by workplace harassment in some cases. Consulting with an employment lawyer can clarify whether this restriction applies to you.

Can you sue your employer for harassment if it involves a co-worker?
To strengthen your case, you must follow several steps. First, document all incidents of harassment. Keep a detailed record of each occurrence, including dates, times, and the people involved. Save any emails, text messages, or other communications that demonstrate the harassment. Second, report the harassment to your employer through formal channels, such as your supervisor or the human resources department. Submitting a written complaint ensures there is a record of your efforts to address the issue. If your employer does not respond appropriately, this lack of action may serve as evidence in a legal claim.
Additionally, witness statements can support your case. If other employees have observed the harassment, ask them to provide written accounts. Their testimony can corroborate your claims and reinforce your legal argument. If your employer retaliates against you for reporting harassment—such as by demoting you, cutting your hours, or creating a hostile work environment—you may also have a case for reprisal, which is prohibited under Ontario law.
If you are considering legal action, it is crucial to seek legal advice as soon as possible. An employment lawyer with experience in workplace harassment, constructive dismissal, and disability discrimination can guide you through your options. They can help you assess the strength of your case, gather evidence, and pursue appropriate compensation.
So, can you sue your employer for harassment if it involves a co-worker? Yes—if your employer fails to address the harassment or provides an unsafe work environment, legal action may be an option. You do not have to face workplace harassment alone. Reach out to an employment lawyer to understand your rights and protect your well-being.
