Get a lawyer and make the cold ba@#$!ds
Stella's right.
It's absolutely, totally, completely IRRESPONSIBLE of them to expect him to take a bus home.
The train, well, Amtrak does have sleeper cars, etc., that can accommodate his need for his leg to be elevated, AND IT DOES need to be elevated and iced regularly. Icing an injury is effective for up 72 hours for pain management and also to reduce swelling, etc. If he's not in a cast, he should be icing his leg 20 minutes out of every hour, as long as he's awake.
He already has grounds for a lawsuit, both against Swift and also their Workers Comp med provider, IMNSHO.
Look, I fell last winter at work--there were wet leaves on wet steps in a rainstorm, and I just slipped, and I actually bruised my shin BONE because I landed on the edge of the steps. And I walked OUT of the WC emergency clinic with narcotic painkillers in my hot little hand, along with half a dozen ice packs, 4 6" Ace wraps, a pair of crutches and orders to stay off my feet for a week--and returned to the doc to be told yeah, another 4 days off your feet, and I'll look again. I continued to receive appropriate pain meds in my hand at the clinic--high dose ibuprofen, tapering down to OTC level ibruprofen, all thru the period I was allowed to be at work, but was required to keep my leg elevated, and restricted from walking distances of more than 100 yards, and I had to see the doc every week for a month, then every 2 weeks for another 2 months to check my progress. I was still asked if I needed any pain meds for my leg on the very day I was released to full duty work, and the doc asked for a 3 month followup then. FOR A BRUISED BONE! Not a broken one--a bruised one.
I can't stress this to you strongly enough: THIS IS NOT HOW A WORKER'S COMP INJURY SHOULD BE BEING HANDLED. Worker's Comp is supposed to be about making sure that the injured party can go back to work at 100%, thus avoiding the need for lawsuits.
There is a serious issue here, and you're going to need an attorney. I will bet you a quarter that they're going to try and say it's his fault, it's not worker's comp, and try to stick you with the bills, including the hotel. I've seen medical records of it happening to people who were "in training" before--all the letters disputing who's responsible, why bills aren't being paid, credit ruined, medical services denied--it's a disaster in the making.
Call an attorney, and do it now. The more I think about it, the more I'm getting scared for you and your hubby, because my BIL is a trucker, and I can see this happening to him SO easily.
Please, please call an attorney. Before you even talk to Swift at this point, call an attorney.
