“Social network spying on job candidates could reduce the attractiveness of an organization during various phases of the selection process, especially if the applicant pool at large knows or suspects that the organization engages in such screening,” Stoughton notes. “Because internet message boards and social media provide easily accessible forums for job seekers to share their experiences and opinions with others, it is very easy for a soured applicant to affect others’ perceptions of an organization.”
