Abstract
A private detective in Slovenia may perform detective activities as an independent profession or on the basis of an employment relationship for a natural or legal person with a registered private detective activity (ZDD-1, 2011). Private detectives completed a questionnaire when they attended the annual training in June 2018 – almost half of Slovenian private detectives participated in the survey. The study results show that almost half of self-employed private detectives investigate more drug abuse at work and abuse of competition clauses, while private detective agencies conduct more civil, legal, and administrative proceedings than other organisational forms. Some private detectives do not perform private detective tasks as their main activity, but as a secondary activity, and those individuals for whom private detective work is their primary/main profession mostly deliver packages, write reports and collect debtors’ data on behalf of their clients.
