Wasn't this the guy with vast amounts of money and the young gf who blocked him on facebook?
Usually the vast majority of claims go like this when they are work related:
1.no win no fee guys offer you a stupidly good offer too good to be true
2. you give your rights to accept settlements to them
3. rather than follow through on a claim to get to get the promised amount of money, they accept the first small settlement that comes along. This is usually quite small and is offered regardless of whether your story has any substance to it because the company does not want to waste time and money, let alone deal with the trouble behind the claim
4. NWNF guys accept said heavily reduced settlement on your behalf and take considerable portion because they don't want to waste their time and money with the process
5. you get a payoff that will pay for a heavy weekend of boozing... if you stick to weatherspoons
That said, no one wants to have to deal with people who throw claims around because they think they deserve any money they can pocket. People tend to find out the sort of person you are and a lot of people would not hire you you are known as a troublesome sort. This is doubly true for trades where people tend to know each-other and carry a risk of injury (anything hands on requires skill and is physically demanding eg. mechanic)
