I resigned from a small establishment a year ago. The establishment has a website, pops up on google search and I left on good terms with my employer who also happens to be my immediate supervisor. However, I did not leave on good terms with most of my co-workers, most of whom still work there. I'm worried that in case of a site visit by CIC officials or 3rd party investigators, my former co-workers might screw me over. In case of site visits, do CIC/3rd party officials talk to co-workers or do they just talk to the person mentioned in the employment letter?
