settlement offers?

[robert32bart]

I am having trouble trying to figure out what is due to me as settlement? I fell at work and had to have a/c surgery on my left shoulder (I am right handed). I was off 6 months almost to the day. The first offer I received was figured at 7.5% I am wondering how this figure is determinned? first what is the norm for my type of injury, I have read that 15% is norm but talking to one lawyer I was told 25%. second 25% of what? I have seen alot of figures from 323 weeks compensation to 440. and lastly at what rate is it figured? is it x amount of weeks at the weekly adjusted workers comp rate or is it x amount of weeks at my average income for the last 52 weeks?

The reason I am asking is cause its a huge difference in pay calculations because my job is based 50% on overtime wages so the workers comp rate per week actually was just under 50% of what I was making per week.

I should also mention that because of the a/c injury it did wear a small tear in my rotator cuff which my surgeon "cleaned up" but did not repair saying it was small enough to not be a concern, but also told me it would never heal on its own. Dont know if that makes a difference or not.

I am concerned because being a truck driver I can do my current job, but if anything happened to this employment I would not be able to accept a few other types of driving jobs because of the injury, ie. Flatbed work or low-boy work as my left arm is not able to reach high up enough to strap or chain down loads

Forgot to mention I live in Illinois
