First, I'll share with you what I think about whether or not data collection should be part of this. Data helps to inform a lot of the decision-making on these processes, what the outcomes are and whether they are effective or not, but the confidentiality of the process must be safeguarded. Aggregating outcomes and not specific situations I think would be helpful in understanding what repeated issues are happening and why they're happening. It would also be helpful in looking at the root causes of that for accountability for an organization.
If an organization is able to identify that they've had hundreds of these complaints and that this was the recurring theme, from that perspective they may be better positioned to have a change in workplace culture. But that has to be protected in terms of who the complainants are and what their experiences are, particularly on their journey to recovery.
I don't have an answer for you on the collection of data currently or on how or if that is mandated.
