Hey there:) I had a recent client (called in to complete an independent review of an incident) who (long story short) had serious shortfalls - namely the at risk management of students (an educational facility). Found out after not much digging that a certain group of staff had been complaining about the unsafe practices for over a year. Pretty shocking to say the least. I advised one of the Health and Safety Reps (who I had been talking to as part of the investigation) to issue a PIN. They did so and now they HAVE TO put processes in place and was also a key recommendation in my final report. Interestingly another finding in my report was lack of transparency. The CEO didn't even mention the PIN had been issued to me and when I raised it looked completely shocked! ha! I think this is the perfect scenario to issue one. Finally some action - or as the Rep recently told me - has now opened a hornets nest! Also (and I am not surprised as I used to train rep courses) the OFFICERS didn't even know what a PIN was, so once again the importance of training for boards to enforce H and S reps are there to ensure the safety of all in the PCBU and should be seen as a positive when things are raised for them to ACTION and FIX. If not PIN is an obvious choice.
