Testimonials
I highly recommend this course for anyone who conducts investigations in the workplace, especially in unionized environments.
– Greg Johnson, Investigator, WestJet
The ability to participate with the class as witnesses and to watch others as they work through complex cases was truly a gift. Because of the need for confidentiality, most times we interview people by ourselves and rarely get any feedback on our interview skills when it is needed most — dealing with difficult witnesses. Thank you RT for this rich, realistic learning opportunity!
– Barb Hamblett, District Principal of Human Resources, Kamloops-Thompson School District
RT does an incredible job of making these workshops interesting, and their investigation knowledge combined with their human rights background makes this program a necessity for anyone new or seasoned in investigations.
– Paula Demers, Manager, Human Resources, City of Vernon

– Greg Johnson, Investigator, WestJet
The ability to participate with the class as witnesses and to watch others as they work through complex cases was truly a gift. Because of the need for confidentiality, most times we interview people by ourselves and rarely get any feedback on our interview skills when it is needed most — dealing with difficult witnesses. Thank you RT for this rich, realistic learning opportunity!
– Barb Hamblett, District Principal of Human Resources, Kamloops-Thompson School District
RT does an incredible job of making these workshops interesting, and their investigation knowledge combined with their human rights background makes this program a necessity for anyone new or seasoned in investigations.
– Paula Demers, Manager, Human Resources, City of Vernon
