Hey Ffion this is a good one, thanks for starting this discussion
From what I've heard, (it's been a mix, to your point), the all employees route usually applying to the initial screening at time of hire, and then high risk roles have periodic screening.
ultimately, ive seen two buckets: risk-based screening, and then role-based, (not sure how common role-based is). But I have more to learn in this specific realm, so I too would like to hear what others have seen out in the industry. curious how many of you are doing true role-based vs. risk-based and whether that distinction came up in audit.
ultimately if theres a clear policy, evidence to support, and rationale (of course with good framing), that would make for solid auditor acceptance
