My question involves workers compensation law for the state of: MN

My fiance works for a company that manufactures ammunition. While working on a machine a bullet exploded and shot him in the chest. He was rushed by ambulance to the hospital where he had chest tubes placed due to a collapsed lung. He was in the hospital for a few weeks then off and on during the first year for surgery and monthly dr appointments. The insurance company took care of all of his dr bills and workman's comp paid him while off of work. He is still currently employed full-time at the same company. We talked to a lawyer right away because everyone was telling us that he could get some kind of settlement. Well...the guys didn't do much for us at all...I mean no information or anything... He has reached "maximum medical improvement" and has lost about 30% of his lung function. He is still living in pain...he was on pain medication but decided to stop using them for fear of becoming "addicted" to them. My question is...What is our next step? Can he get a settlement? Who do we need to talk to?

Oh yeah...the lawyer we had gave us a sort of sliding scale of how much money he could recieve for each percent of funtion lost...is this all he could get? How and when do they pay?
