OLB Clarifies Constructive Dismissal and Harassment Claims
In a recent decision, the Ontario Labour Relations Board dismissed a constructive dismissal application brought by a former supervisor at Metrolinx, finding the employee had voluntarily resigned rather than being forced out by a toxic work environment.
The case Deborah Tucker v Metrolinx, 2024 CanLII 60457 (ON LRB) offers important guidance for Ontario employers on workplace harassment, performance management, accommodation, and how employer conduct is assessed in constructive dismissal claims.
This article breaks down what happened, what employers need to know, and how to proactively manage similar risks in your workplace.
What Happened in Tucker v Metrolinx?
Deborah Tucker was a long-time employee of Metrolinx, advancing from bus driver to supervisor. In 2022, she alleged she had been constructively dismissed due to an increasingly toxic work environment, citing “unprofessional and degrading” emails, delayed harassment investigations, and disciplinary actions she believed were retaliatory.
She claimed her manager’s communications, including suggestions to “slow down” and reminders to check grammar, amounted to harassment, and that the employer’s failure to accommodate her anxiety and investigate her complaints promptly left her no choice but to resign.
However, the Board concluded:
- The emails were professional and within the bounds of supervisory duties.
- The harassment investigations were not unreasonably delayed.
- The performance management measures were justified and not retaliatory.
- No formal accommodation request had been made, and Metrolinx’s duty to accommodate had not been triggered.
- Her departure was voluntary, especially as she had accepted a new position at Oakville Transit before asserting constructive dismissal.
Ultimately, the Board found no fundamental breach of the employment relationship and upheld the Ministry’s refusal to award termination or severance pay.
As Christopher Achkar, employment lawyer and founder of Achkar Law, explains:
“Clear policies, fair performance management, and timely responses to complaints are your best defense. The Tucker decision reminds us that not every complaint amounts to legal liability, but due diligence is key.”
Why This Case Matters for Ontario Employers
1. Not All Difficult Communications Equal Harassment
The Board reaffirmed that not every abrupt or direct managerial communication amounts to harassment. In this case, references to “slowing down” and correcting grammar were found to be part of routine oversight rather than bullying or abuse.
In reviewing the case law, the Board noted that employers retain some latitude to manage their operations and workforce, even where their direction is firm or critical.
2. Performance Management Must Be Grounded, But It’s Not Retaliation by Default
Ms. Tucker received a Performance Improvement Plan (PIP) and prior warnings for procedural errors and dress code issues. The Board determined these measures were initiated by her direct supervisor and were based on valid performance concerns, not retaliation for her harassment complaints.
Employers should ensure that performance management is well-documented, procedurally fair, and not disproportionately timed to employee complaints; however, they retain the right to address legitimate concerns.
3. Accommodation Obligations Require Clear Triggers
Tucker claimed her employer failed to accommodate her anxiety, yet the evidence showed she never made a formal request or provided sufficient medical documentation until after her resignation.
Employers are expected to act on accommodation needs when they have sufficient information, but are not required to guess or assume that an employee requires accommodation.
4. Constructive Dismissal Requires a Serious Breach
To succeed in a constructive dismissal claim, an employee must prove that the employer fundamentally altered the employment relationship or created intolerable working conditions.
In this case, the Board found:
- The communications were supervisory, not abusive
- The investigations were reasonable
- The PIP and warnings were valid
- The employee resigned to take another job
Together, these facts did not meet the high threshold required to establish constructive dismissal.
- No. For a constructive dismissal claim to succeed, the employer’s conduct must fundamentally breach the employment contract or make continued employment intolerable.
- Only if the employer has sufficient knowledge of the condition or receives a formal request. Employees must provide enough information to trigger the duty to accommodate.
- Not by default. Legitimate, respectful performance management, even if critical, is generally not harassment.
- A request that includes clear communication of a disability and how it affects work, along with medical documentation, generally constitutes a formal request.
- Yes. Our team offers policy development, training, and legal advice to help employers meet their legal obligations and minimize risk.
