When you are leased on to multiple carriers at the same time, it is true what, Jefferson is saying about being a top priority with each individual carrier at certain times of the week. The flip side to that is "if you are that carriers only driver in a certain area, they will pick up the phone and call you on every load they see" because like us, they are also out here to make money. The reason why the companies that I haul for allow "and even encourage" me to work for other people is beacuse there is a lot of competition for cargo van freight, and they don't want to be solely responsible for my success and/or failure out here.
There are times when conflicts arise and this is to be expected. I have one company who has customers that the other three can't see and occasionally they will get a little bit upset if I get a load out of one of their hot areas with another carrier. They will say it sucks that I couldn't be there to cover the load but not to worry too much because they had an outside partner carrier in the area who covered the load. Also, there has been only 2 instances where two companies were bidding on the load at the same time. This can be somewhat beneficial to the driver, but detrimental to the bidding process.
I have had at times only one company call me on a really good load because the other two companies were too busy to watch the boards. This is where having multiple dispatch teams looking for loads comes in handy. Even when you are exclusively leased on to one carrier, it doesn't automatically mean that getting you a load is their number 1 priority that day. I have worked for larger carriers that have never called me on loads even though I was sitting right in the area when they popped up on different boards.
With all that being said, it is sort of selfish for a cargo van driver to lease on to multiple carriers at the same time as it is a way to buck the system and make more money. But on the other hand, it is extremely selfish for a company with limited resources to require a van to be exclusive in todays difficult business environment. I would not condone doing this in a straight truck though, because from what i've seen, even a tiny company should have no problem keeping a straight trucks wheels turning. This set of cirsumstances is for vans, sprinters, and box trucks only. We are in a completelu different vehicle class and we have the flexibility to operate in this manner regardless of what some people have to say about it.
