don't worry too much ar.. at this stage, 紅豆爸 needs your support a lot gar.
"因工傷" should be able to claim insurance (company should have bought gar) ... it doesn't matter how many months you worked for the company gar. If the company didn't buy insurance, then you should seek help from the labor department ar.
By the way, any other financial support (like from the government) can apply ar??
if 紅豆爸 can't 做回老本行, then try to look for other field to switch to la.... can he learn some new skill.. like fixing computer ar... ?? maybe online business??
