H&S as a function of HR? Hi Michelle.
I'm undecided if HR and H+S are natural / comfortable co-functions or need to maintain a collaborative tension. It's a questoin of the philosphy and paradigm that the organisation puts in place when establishing the functions and the expecations and desicion making authoirity that each funciotn holds. Again, this is somehting I'm still mulling over and considering.
My experience has most certainly been that the two functions are in tension with each other, in part by my philosphy around H+S. The businesses I've been involved with the HR function hs been protectionist: holding infromation close, looking for 'whose at fault', holding the worker accountable for under performance - ignoring the working environment. This runs contrary to my H+S approach of openly sharig experinece and insight, examining the work environment in order to optimise work and understanding the underlying drivers for worker performance, enabling the capacity to 'fail safely'. It has been an uncomfortable tension, however one that consisently produces robustly test positive outcomes. The catch though: if one team / function was subservenant (reports through) to the other, the power imbalance results in poor, even bad outcomes.
My opinion, based on a large pool of data, is the NZ workpalces absolutley have to improve their H+S performance. They must change. And you don't generate chage by placing your change agents (H+S Practicioners) inside a well established business unit that has no driver for change.
