It is also helpful to consult a variety of resources, including company policies, certificates, wage slips, and records.
Speaking with relevant colleagues, for example health and safety officers and human resource managers, is also
important to gaining a clear picture of the realities at your facility. Workers in your facility are a valuable resource,
and it may be impossible to get accurate information without their input. Interviewing workers will be particularly
important if your facility employs migrant workers either directly or through a broker.
