trucking companies

well I have been a driver for over 38 yrs and let me tell you all that they are all bad in one way or another, and another thing im also a mechanic of class 8 trucks?? just saying that companies do not care about the driver safety at all they just put you in the seat and just care about making them money wheather your 100% or not. I was injured on the job in may 2013 and have had not help with medical people where I went for treatment they said it was a bruise put me on light duty for three weeks, My operations manager treated me like I was a nobody for these three weeks, So I told them that my hand that was getting worse and was going numb on my all the time. and this time was treated like I was liying so the company is not a very good place unless your a kiss a--. And im not that so fraley and schilling is ok until you get injuried on the job and or their for 90 days its good then it turns to crap there??
