The main office recruiter who hired me was ok, but the onsight supervisors & manager were downright despicable in how they treated their employees.
After some time [I worked a contract for a few years] I had an old injury flare up & was treated lower than low class.
I'm not sure if it was becuz of the atrocious atmosphere from the contract company or they just had lousy sups at the company.
My work experience tells me it was the company.
If it was not a cancer throughout then these problems would not have been so prevalent.

My advice: IF you're desperate, check 'em out.
If not, stay FAR AWAY from them.
You will definitely find better elsewhere.
