The only reason I say I would be inclined not to take it further if it was a small business would be that they are probobly struggling anyway at the minute, If it is a smaller business then this guy could have been aware that the machine he was using wasn't fully protected, if that's the case and he used it anyway it's kinda his fault. I was allways told that if I was unhappy with any aspect of a machine, not to use it, stories like these only enforce that. Obviously he's within his right's to try and get some compo, but personally I wouldn't if I knew that guards had been removed and worked on the machine anyway, I would have been asking for trouble.
