Jeff has extensive experience dealing with the accommodation of the disabled in the workplace. He has been counsel in a number of leading cases in the field of workplace drug and alcohol testing. As pro bono counsel for the complainant and the intervenor, Canadian Civil Liberties Association, Jeff won the Entrop v. Imperial Oil decision which recognized alcoholism and other forms of substance abuse as a handicap under Ontario's Human Rights Code and held that random workplace drug testing may be discriminatory. Jeff was also counsel for the International Union of Operating Engineers in the Sarnia Cranes case where the Ontario Labour Relations Board struck down the employer’s alcohol and drug testing policy.

Jeff has authored a number of articles on labour relations matters, privacy and drug testing, and assists George Adams on an ongoing basis with the publication of the leading text Canadian Labour Law. As well, Jeff’s interest in law reform and public policy development led to his appointment as a counsel for George Adams in the public consultation he conducted for the Ontario Government concerning Ontario’s Special Investigations Unit which investigates police action resulting in death or serious injury.
