I think it really depends on the situation case by case. If there are allegations brought forward about an individual over the course of the investigation, they may have to be brought in to the investigation obviously to address the allegations. It's case by case depending on the situation. Oftentimes what we find in some of our workplaces, if it's in a plant setting, for instance, where there are numerous people around, there may have been people who witnessed some gesture, comments or unwelcomed behaviour.
It really would depend on the nature of the incident whether or not the individual who had been accused of the harassment would be brought into the picture. I would say that probably more likely than not that would have to be the case in order to do a thorough investigation.
