It doesn't matter where you work,if the fit is right, you will be ok,if not,you will be asking alot of questions.I make money where I am,but there have been many leave, cause they couldnt make it here.
In the beginning it was easy,but now there is lots of competition,both in your own company and other companies, vying for the same freight,and of course the customer is looking for cheapest way for him to ship.Myself I like working on a percentage contract,others will say mileage pay is the only way,so you have to see what suits you.
Remember one thing,there are busy times and slow times,in expedite, you make hay while the sun is shinning,dont be sitting home during the busy times,then complain your not making money when its slow,or you will be jumping from company to company.
