Videoconference with Katherine Lippel, Canada Research Chair in Occupational Health and Safety Law, (U. of Ottawa). In Canada, employers, insurers and some workers\' compensation boards rely on private detectives who use clandestine surveillance methods as part of their strategy to insure that workers are not receiving more benefits than those to which they are entitled. This presentation will explore the usefulness and limitations of these practices, discuss results of a study on the effect of such practices on the health of workers, and concludes with consideration of the effect of stigma on workers\' health and on the reputation of compensation programs and a discussion on the human rights of claimants.
