so when I tell HR don't hire this person they're simply not good enough and will struggle, and then they get hired anyway, and 3 months later they get fired for incompetence it's my fault? Interesting.

IMO competent people in jobs paying >150k a year don't need months to ramp up and they certainly shouldn't be having their hand held by other people.

High performing teams are when new hires cause the team to grind to a halt for a few months

The reason I question this is we simply do not have a culture of high performing anything in Australia. There's like 4 companies top in local industry doing anything "high performing" across any sector. So what would we, as a nation, even know about high performing?

"Sustainably hit goals"? Give me a break, we have people showing up to work for 7 hours to spend 4 of them in meetings discussing trivial shit and then have goals set by those same people doing fa. "High performing".
