This is the tricky part. As far as I’m concerned, unless there were previously known about conditions then the club is treating the players the same. I don’t know that for a fact but let’s assume. Now if this incident was the first time Jackson had mental distress, then as long as the club support him and offer professional help, what more can be done? The actual “punishment“ will be analysed, but as has been mentioned a lot, will it differ much from other difficult training methods?
It’s an unusual situation because part of NRL players’ jobs is going beyond the normal level of fatigue etc. I’ve worked a tough labouring job, lifting and dragging heavy loads in up to 45c heat, but I could take a break when I was buggered. When you’re in the middle of an NRL match, you can’t generally do that. I watch Curran and Kikau and wonder how tf they can handle it, but handle it they do and they still perform at a high level. They’re the examples to say, this is the level that an elite NRL player must reach and maintain. Look at some of the efforts in origin matches!
NRL and professional sport in general is an unusually highly demanding career. Duty of care etc is still required of course, but one of the key factors is having the mental fortitude to handle it, so if this actually does go to court (which I doubt) it would be interesting how they view it.
We also should remember there’s some other similar player welfare issues ongoing, e.g: Keith Titmuss’ passing, after gruelling training in excessive heat.
