Workplace investigations are rarely straightforward. In many cases, what initially appears to be a harassment complaint may also involve allegations of workplace violence, concerns about an employee’s medical condition, or requests for accommodation.
When these issues overlap, employers face a complex challenge: they must investigate workplace concerns thoroughly while also meeting their obligations under occupational health and safety legislation, human rights laws, and privacy requirements. Across Canada, these obligations are shaped by provincial occupational health and safety legislation, human rights legislation, and guidance from organizations such as the Canadian Centre for Occupational Health and Safety (CCOHS).
Understanding how these obligations intersect is critical for employers seeking to protect employees, reduce legal risk, and maintain a respectful workplace.
Why Overlapping Workplace Issues Create Additional Risk
Many workplace complaints do not fit neatly into a single category.
Consider the following examples:
- An employee alleges workplace bullying and later discloses a mental health condition that may be contributing to workplace interactions.
- A manager reports threatening behaviour from an employee who subsequently requests accommodation for a medical condition.
- A harassment complaint reveals underlying interpersonal conflict linked to a disability, family status obligation, or other protected ground.
In these situations, employers must carefully balance multiple responsibilities at the same time.
Failure to do so can result in:
- Human rights complaints
- Occupational health and safety concerns
- Privacy breaches
- Procedural fairness challenges
- Increased litigation risk
Understanding the Three Key Areas
Workplace Harassment
While definitions vary by jurisdiction, workplace harassment generally involves inappropriate conduct, comments, or behaviour that a reasonable person would consider unwelcome.
Examples may include:
- Repeated disrespectful conduct
- Verbal abuse
- Bullying
- Sexual harassment
- Discriminatory comments
In many provinces, employers have a legal obligation to investigate harassment complaints and take reasonable steps to address concerns. The Canadian Centre for Occupational Health and Safety (CCOHS) identifies workplace harassment as a workplace hazard that employers must address through prevention, reporting, and investigation processes.
Workplace Violence
Workplace violence generally involves:
- Threats of physical harm
- Intimidation
- Physical assault
- Aggressive or threatening behaviour
Occupational health and safety legislation across Canada requires employers to take reasonable precautions to protect workers from violence and safety risks. Guidance from the Canadian Centre for Occupational Health and Safety (CCOHS) emphasizes that employers have a responsibility to assess risks, implement controls, and respond appropriately to incidents of workplace violence.
In British Columbia, employers also have obligations under the Workers Compensation Act and WorkSafeBC requirements to address workplace bullying, harassment, and violence. WorkSafeBC specifically requires employers to establish policies and procedures for reporting and investigating complaints.
Accommodation Obligations
Accommodation obligations arise when an employee requires workplace adjustments due to a protected characteristic under human rights legislation, such as:
- Disability
- Mental health conditions
- Family status
- Religion
- Other protected grounds
Employers have a duty to accommodate to the point of undue hardship under applicable human rights legislation. The Canadian Human Rights Commission recognizes accommodation as a shared process between employers and employees.
Importantly, accommodation obligations do not eliminate an employer’s ability to investigate workplace concerns. However, they may affect how the investigation is conducted.
When These Issues Overlap
The most challenging investigations often involve more than one issue.
| Issue | Employer Obligation |
| Harassment Complaint | Investigate allegations fairly and promptly |
| Violence or Safety Concern | Protect employee safety immediately |
| Accommodation Request | Assess accommodation needs and engage in the accommodation process |
| Human Rights Concern | Avoid discriminatory decision-making |
| Privacy Considerations | Protect confidential personal information |
Employers should avoid treating these obligations as separate processes. Instead, they should assess the situation holistically while ensuring each legal obligation is addressed.
A Step-by-Step Approach for Employers
Step 1: Conduct an Initial Risk Assessment
Before launching an investigation, determine:
- Is anyone at immediate risk?
- Are interim measures required?
- Does a workplace safety concern exist?
- Are accommodation requests involved?
Where violence or harassment allegations are involved, employers should assess risks promptly and implement interim measures where necessary, consistent with occupational health and safety requirements.
Safety concerns should always be addressed first.
Step 2: Separate the Investigation from Accommodation Decisions
One of the most common mistakes employers make is assuming an accommodation request prevents an investigation from proceeding.
In reality:
- The investigation can continue.
- Accommodation needs should be assessed simultaneously.
- Appropriate adjustments may be made to support participation.
For example:
- Additional breaks during interviews
- Modified interview formats
- Support persons where appropriate
- Flexible scheduling
Step 3: Gather Information Carefully
Investigators should:
- Interview all relevant parties
- Review documentation
- Collect electronic evidence where appropriate
- Maintain confidentiality
When accommodation concerns exist, investigators should focus on workplace behaviour and facts rather than medical diagnoses.
Step 4: Apply Procedural Fairness
All parties should have:
- An opportunity to provide information
- A fair chance to respond to allegations
- Clear information about the process
Procedural fairness remains essential regardless of whether harassment, violence, or accommodation concerns are involved.
Step 5: Implement Appropriate Follow-Up
After findings are reached, employers may need to:
- Take corrective action
- Provide training
- Adjust workplace practices
- Implement accommodations
- Review policies and procedures
An investigation should not simply end with a report. Employers should address the root causes identified during the process.
Common Mistakes Employers Make
Organizations frequently create additional risk by:
Delaying the Investigation
Waiting too long can worsen workplace conflict and increase legal exposure.
Treating Accommodation as a Shield Against Investigation
Accommodation needs may affect the process, but do not eliminate accountability for workplace behaviour.
Failing to Address Safety Concerns Immediately
Safety risks should be assessed and managed before the investigation progresses.
Asking for Excessive Medical Information
Employers generally need information about restrictions and limitations, not diagnoses. Human rights authorities consistently advise employers to focus on functional limitations and accommodation needs rather than requesting unnecessary medical information.
Using Internal Investigators with Conflicts of Interest
Complex matters often benefit from an external, neutral investigator.

Frequently Asked Questions
Can an employer investigate an employee who has disclosed a disability?
Yes. Employees remain accountable for workplace conduct regardless of disability status. However, employers may need to accommodate the employee during the investigation process.
Should an investigation stop if an employee goes on medical leave?
Not necessarily. Each situation should be assessed individually. In some cases, investigations can continue while accommodation needs are addressed.
When should an external investigator be used?
External investigators are often recommended when complaints involve senior leaders, allegations of harassment or violence, multiple parties, potential human rights concerns, or situations where neutrality may be questioned.
