NHAnn is right.
My DH was injured on the job (hit by a front end loader) in '96. Many surgeries and physical therapy until 2001. He has lost 34% mobility in his knee.
Workers comp paid him a % of his wages, plus all dr's bills, pt bills, mileage to and from, prescriptions, etc. He went back to work on light duty, but the company downsized eliminating his position when he could return full time.
Workers comp had to pay to retrain him in a new field. After a year of company training, he realized it wasn't for him and went back to construction as a heavy equip operator, which he was before, but could not do so until after the settlement was done.
Whenever there is a loss of mobility, loss of an extremity, etc..employees are supposed to be compensated since it was work related.
I urge you to retain a lawyer to protect your DH's rights as an employee. This will cost you nothing unless their is a settlement and the lawyer will get a % of it.
These things can take years, ours was 5 years. Keep documentation of everything, receipts, medical bills, etc. for the lawyer.
If your DH was hurt due to negligence on the employers part, he will be compensated in some form.
Best wishes to both of you, sorry to hear about his injury.
