How does research evidence change the advice you give? There's no doubt people discussion work challenges, hazards, or safety norms can make a big difference. Where I have some doubts is whether management should try and lead or take over the process all the time. It's quite natural for people to discuss hazards and challenges, just as people look for hazards regardless of whether there is a Take 5 policy. In that regard, providing shared crib rooms, break times, having project timelines or maps available, making it easier for workers to talk to each other, might do more to foster discussions than formalised forums.
