McMahon Molyneaux Henriquez’s labour and employment lawyers are focused on fighting for justice for workers’ and marginalized members of the Hamilton and surrounding communities. We prioritize cases that address workplace injustice. This includes wrongful dismissal, constructive dismissal, severance package reviews, employment contract reviews, workplace harassment or workplace bullying cases, including sexual harassment claims, workplace discrimination, maternity or parental leave issues and toxic work environment claims.

In addition, the labour and employment lawyers at McMahon Molyneaux Henriquez support in developing the policies and practices in workplaces to help make them more inclusive, with accessible employers and service providers. This includes developing policies (such as human rights policies or occupational health and safety procedures), providing human rights and employment standards training, and investigating discrimination and harassment complaints.

We are known for providing high-quality supportive, progressive and inclusive labour and employment law services for all workers in Hamilton and southwestern Ontario.
