I'm writing a text about harrassment at the workplace, and about what measures the workplace should take in case of suspected harassment. Now I'm wondering what to call the process in which the workplace looks into the alledged harassment – should I use "enquiry" or "investigation"? I have tried googling different phrases with "investigation" together with "harassment" and "enquiry" together with "harassment" respectively, on British sites, but I get too few hits to be able to draw any conclusions. Nor do my dictionaries help much. So, I'm hoping you can help me :)
Also: what do you call the people conducting the enquiry/investigation? Does "investigator" work?
