Prior to becoming a lawyer, Jamie worked with the Ontario Royal Commission on Asbestos during which he interviewed nearly one hundred unionized workers who were suffering from asbestos related illnesses. He then worked as a research assistant in the national office of the International Association of Fire Fighters and for the Public Service Staff Relations Board (now the Public Service Labour Relations Board).

Jamie Wyllie also taught industrial and labour relations for 15 years at Carleton University, and during that period was a proud member of the Canadian Union of Public Employees (CUPE). With such a broad background in the labour movement and in the study of labour relations and labour law, Jamie began representing an international union while still an articling student in 1985. Over the course of his 25 years in legal practice Jamie represented unions in both the private and public sectors and proudly carried on his father's legacy of representing working men and women. Like Jamie Wyllie had done, David Spears has been working exclusively in employment and labour law since his call to the bar in 2000. He has represented unions in a wide variety of labour relation matters including grievance arbitrations, labour board proceedings and collective bargaining.
