In particular, she has assisted employers in carrying out investigations following serious or fatal workplace accidents. She has also intervened on matters of subjection of construction projects to the R-20 Act. She has been involved in the implementation of work procedures in companies to ensure compliance with occupational health and safety legislation, as well as with auditing and improving internal mechanisms to control risks and dangers present in the workplace environment.

  1. Telework: Better Safe

    Telework is not a new phenomenon. According to the International Labour Organization, its rise dates back to the 1970s when a major oil crisis prompted many companies to keep their employees at home to reduce their energy consumption1. That said, since the Covid pandemic, teleworking has become widespread. Now, nearly a quarter of Canadian companies (22.5%) expect that 10% or more of their workforce will continue to telework after business is back to normal2. Needless to say, this mode of work is here to stay. However, teleworking can be a real headache for employers when it comes to injury prevention and occurrence. A more permissive caselaw The Act Respecting Industrial Accidents and Occupational Diseases3(the "AIAOD") may apply to homeworkers4. In fact, the courts have long held that a home can be considered a workplace within the meaning of this Act, where there is part of the work that is performed by the employee with the knowledge and consent of the employer5. In fact, before the pandemic, there were two opposing lines of caselaw regarding the acceptance of workplace injuries when they occurred in the home of the worker who was duly authorized to work remotely. One accepted them, the other denied them. However, it was all a question of circumstances. If the situation fell within the sphere of professional activities, it was accepted, even if it could be considered as part of the personal sphere. 6 However, since the pandemic, in 2020 and 2021, the Administrative Labour Tribunal (the "ALT") has issued several decisions expanding the boundaries of this sphere of professional activities. Several so-called "comfort" activities have been admitted in the context of teleworking, such as falling while walking during a health break7or on the stairs at home at the beginning of the lunch hour8. Similarly, going to the bathroom9, going outside to smoke10, getting a soft drink11, a coffee12, or a dish from the microwave13 could qualify as comfort activities within the sphere of work activities at work, even when teleworking. Although the restrictive trend could still be applied, it is important to note that each situation must be analyzed individually, taking into account the location of the event, the existence and degree of authority over the worker, the purpose of the exercise and its usefulness with respect to the performance of the work. In short, given the increased use of telework, employers should expect to see an increase in such claims. This observation should guide them in the organization of this new work method, especially considering the new amendments to the Act Respecting Occupational Health and Safety (the "AOHS"). Impact of amendments to the Act Respecting Occupational Health and Safety In 2021, the AOHS underwent a number of important changes. One of them is that the Act and its prevention obligations apply to both the worker who teleworks and the employer14. This means that the worker's home or open workspaces are now the employer's responsibility. For example, the obligation set out in section 51(7) of the AOHS, namely that the employer must provide safe equipment and ensure that it is maintained in good condition, applies in this case to the telework environment where the worker is located. This new reality entails obligations for employers and will undoubtedly have an impact on the courts' interpretation of the acceptance of an employment injury. Indeed, as shown in the previous section, recent decisions tend to demonstrate that accidents that occur at home in the context of telework are mostly admissible. Moreover, the new obligation set out in the AOHS according to which the telework environment is under the responsibility of the employer in matters of prevention related to occupational health and safety is likely to be interpreted by the courts as being more conducive to the recognition of workplace injuries. The link is certainly not direct, but the trend in caselaw and the amendment to the AOHS lead us to believe that this will be the case. Recommendations in light of the evolution of caselaw and amendments to the AOHS In light of the above, it would be advisable to establish or revise a telework policy in order to ensure that the obligations of the employer and those of the worker with respect to the telework workplace are clearly defined. For example, depending on the activities that may be carried out, it will be important to define the notion of workplace in a telework environment. To do so, each employer will have to ask itself many questions, such as: Do you want to allow teleworking in a cooperative teleworking location? What measures can be put in place to ensure that prevention obligations are met and that occupational injuries are avoided? Who will be responsible for ensuring that the employer's obligations regarding prevention are met in a context where the employee works remotely? How to manage employees who are outside the country? In short, all these questions will have to be analyzed in the context of drafting or rewriting a telework policy. The members of the Labour and Employment Law team remain available to assist you in your reflection and in the revision of your policy, if necessary.

  2. A dismissed employee’s obligation to mitigate damages in the context of the COVID-19 pandemic

    Over the years, the Quebec courts have repeatedly stated that dismissed employees have a duty to mitigate the damages they suffer as a result of a dismissal. This obligation, which is now codified in the Civil Code of Québec,1 has been adapted to the circumstances of the cases over which the courts have presided. The question, then, is whether the COVID-19 pandemic is likely to have an impact on a dismissed employee’s obligation to mitigate damages. The Administrative Labour Tribunal (hereinafter the “ALT”) addressed this issue in its recent decision Tourigny c. Fonds de solidarité des travailleurs du Québec (FTQ)2 (hereinafter the “Tourigny decision”). Background  On August 30, 2021, the ALT upheld Ms. Tourigny’s complaint against a dismissal made without a good and sufficient cause under section 124 of the Act respecting labour standards.3 The complainant, who held a position as director of the Direction Marketing Investissement department before being dismissed on January 28, 2019, claimed, in particular, the wages she lost as a result of her dismissal up to the date of the ALT decision upholding her complaint. The employer argued that the complainant had failed in her duty to mitigate her losses. For her part, the complainant felt that she had done everything in her power to find a job quickly. It should be noted that the COVID-19 pandemic began while the complaint was being heard in court.  Decision on the obligation to mitigate losses  The ALT reiterated, quoting the decision in Durocher c. Lisam America Inc.,4 that dismissed employees have a duty to mitigate damages resulting from their dismissal, even when they are dismissed without good and sufficient cause. This obligation is one of means and is assessed based on the circumstances of each case using the reasonable person test. The ALT further noted, quoting the decision in Agropur, Division Natrel c. Teamsters Québec local 1999 (Montpetit),5 that the duty to mitigate damages consists of two components, namely (1) to make reasonable efforts to find new employment, and (2) not to refuse an offer of employment that is reasonable in the circumstances. In the Tourigny decision, the ALT confirmed that the complainant had failed to mitigate her losses. As such, it reduced the indemnity for lost wages by $34,000, finding that, given the pandemic and the scarcity of job offers, the complainant should have conducted a more thorough job search and been more open to positions that did not perfectly match the job she held prior to her dismissal. Thus, the ALT stated the following: [69] For the Tribunal, during a recession or even a pandemic, when job offers are less important and less financially attractive than in normal times, one must, on one hand, expect to conduct a more rigorous search. [70] On the other hand, one must be more open to offers which, even if they do not correspond exactly to those held in the previous job, are related to the expertise or jobs already held. [our translation]In short, with the pandemic in mind, the ALT deducted two (2) months of gross salary from the indemnity for lost wages, which amounted to $34,000, because: The complainant had taken two (2) trips abroad of about ten days each in the first few months following her dismissal, and the employer did not have to assume the financial consequences of the complainant’s choice to do so; The complainant had been in a management position for a short time and limited her job search to positions similar to the one she held prior to her dismissal. However, limiting herself to management positions with working conditions similar to those she had with the employer—which were exceptional—did not demonstrate a willingness to mitigate her damages. Thus, according to the ALT, the complainant had set aside several positions that could have provided her with a substantial income; and The complainant had applied for only one job during the first eight (8) months following her dismissal and thirty-eight (38) jobs over the next twenty (20) months, that is, fewer than two (2) jobs per month. Her job search efforts were therefore not considered sufficient. Conclusion In short, the Tourigny decision confirms that the context in which employees find themselves is relevant in determining the extent of their obligation to mitigate the damages they suffer as a result of their dismissal. In theory, employers should not be penalized when a dismissed employee fails to put in the necessary effort to find a job during challenging economic times. In circumstances such as these, arising from, say, a pandemic, a dismissed employee must make greater efforts to find a job, failing which the indemnity paid by their former employer may be reduced considerably.
