With all the laws on the books protecting workers, it's unlikely a company will negligently cause the death or be careless of a worker's life just to cash in on a policy.
ValerieUSA, the example you cite is one I think really does need checking out by authorities. That DOES sound as though the company is deliberately negligent of the workers' lives, knowing they'll cash in on a policy.
If people want to cash in on insurance policies if their loved one dies, then they should take out those policies in the first place. They have no legal right to insurance payout on policies someone else took out.
Stop spreading lies. Every insured MUST sign the application.
