I agree with everyone that this can be very frustrating....but brokers are also some of the worst culprits on this subject. If I had a $1 for every time I called on a load on link that was already gone, or seen "test, no calls" than I wouldn't have to be working today. Brokers do this just as much as carriers do, and its funny how once capacity tightens up how quickly the brokers start to cry the blues on the subject. Does anyone still believe this driver shortage is still a myth fabricated by carriers? Ask any carrier right now, quality drivers and owner operators are very hard to find, or often candidates that do come in the door only want to "run here, or only go there" or they "don't want to do this, or that". Not very often do you come across someone who is just willing to drive.
And yes, carriers do post outbound from Ontario all the time and sometimes they don't have trucks available. But if you ask most carriers, those posting are on there 365 days a year, and rarely do they even generate loads for us, as a lot of brokers (not all) will call 10 carriers posting to the area and just go with the cheapest option available, and then complain when something goes wrong. Reputable carriers will often not be the cheapest option, but will be upfront with you on service and price. Price isn't the "be all, end all" and if you're looking for good service, honesty and integrity then don't pin the reputable service providers against the undependable, unreliable cheaper options, who won't be in business in 6 months.
Everyone is guilty of "not taking something off" the link, as it does happen, but lets look in the mirror before getting upset at the carrier as brokers also do the same (including leaving the load on the link to find a cheaper option).
