Pretty much as the title says really - he says he can't be bothered and why should he. I'm not fussed about him not having any money as he's the one that will be impacted but he does absolutely nothing except go to school and straight to the gym with his mates a couple of times a week but mainly sits on his Xbox all evening and weekend when he's not out socialising.
I think it would be good for him and would break up the monotony of his week, he might enjoy it and frankly, think at 16 he should have a job and he needs to get off his arse and do something worthwhile. He seems to have very little homework so no issues with it impacting school work.
Would it be totally unreasonable to say if he doesn't get a job I'm not prepared to pay for his phone or gym membership? He's gonna through a horrible phase so anything we suggest he refuses on principle but not sure what, if anything, else we can do to motivate him.
