Everyone's on a high horse because of the recent trends(and threads) of rising insurance associated with false injury claims.
As for the 'free money lulz' post. If the family has a loss of income due to the accident then it's fully justifiable. I'm sure he knows the risk of increased premiums and so on.
This is the problem, this guy has a broken wrist FFS. Something that can be seen in black and white on an X-ray and something not even the "whippy compo m8" team on here can dispute being quite seriously debilitating.
I sprained my wrist really quite badly a few years ago - I could not carry out my normal duties in my job for over three weeks - I was fortunate enough that being the family business, I was paid regardless, but how many working class people can really afford to throw three weeks pay away on principle? You're probably looking at longer for a broken wrist, too.
What I would say to the OP is that as long as it isn't going to cause an argument between you and your Wife, then go for it - you need to cover your time off work and the law says you are entitled to compensation, so do it.
No, compensation won't turn back time, but it'll pay for decent medical treatment, it'll cover the money lost as a result of travelling to doctors, physio, hospital, loss of earnings and there will be a chunk left at the end of all that to compensate you for your suffering.
This is the point of compensation, because you can't just magic this stuff away there is compensation instead.
