One important screening tool is an employee questionnaire or survey to get employees’ ideas on the potential for violent incidents and to identify or confirm the need for improved security measures. Detailed baseline screening surveys can help pinpoint tasks that put employees at risk. Periodic surveys – conducted at least annually or whenever operations change, or incidents of workplace violence occur – help identify new or previously unnoticed risk factors and deficiencies or failures in work practices, procedures or controls. Also, the surveys help assess the effects of changes in the work processes. The periodic review process should also include feedback and follow-up. It is important to consider how the data will be used when drafting questions. Responses should be confidential, and the survey should be simple to complete. Allowing it to be completed at work will facilitate a high response rate. A sample employee survey and focus group questionnaire are in Appendix 4.
Independent reviewers, such as safety and risk professionals, law enforcement or security specialists and incurrence safety auditors, may offer advice to strengthen programs. These experts can also provide fresh perspectives to improve a violence prevention program.
