This study aims to identify the prevalence of employee theft and rationalisations for taking company property, to help practitioners reduce workplace theft. The characteristics of workplaces where theft is common are identified, the items most likely to be stolen, the characteristics of the likely culprits, and their justifications for stealing. The study uses a questionnaire to collect quantitative and qualitative data from hospitality workers, whose responses are analysed to determine the severity of employee theft and rationalisations for taking company property. Employee theft is shown to be common, and strongly associated with workplaces where under-staffing and inadequate training are also common. Casual workers, young people, and those paid least, are found to be those most tolerant of theft. By addressing the relationship between social consensus, moral reasoning, and petty theft, the discussion identifies causes of petty theft from an ethics perspective.
