I can give you one reason, I've witnessed employee's and some trainers bullied by other staff at Hatrick, the bullied people went to management and every time the bully won, hence the reason some staff left or were pushed.
Can't remember how many years back but at a members meeting Greg Kerr from GRNZ was present, he stood up after witnessing much infighting and bickering (common place) and said no other club had the bullying, undercurrents and back stabbing that Hatrick had.
He actually employed a independent person to engage with trainers and staff to try sort issues, (I suspect many were to scared to speak up for fear of names leaked and retribution)
Other trainers will remember this, those issues were still present till racing was suspended.
I can see the need for help and support and the benefits to those needing it.
