But you forget... the market is the ultimate judge here.
If every LTL carrier was unionized, or paid union-comptetive wages and bennies, it would make shipping somewhat more expensive. But look at the fact that LTL carriers have been raising rates and tacking on fuel surcharges, and yet most carriers are seeing freight volume growth in double-digits annually.
Remember, it wasn't but a couple of decades ago that most of the industry was unionized. Then deregulation was forced down the industry's throat.
Did the drivers win? No, because if you look at average wages adjusted for inflation, even union drivers today are making less than in the Seventies.
So... who did win? The shippers did, that's who. They got far greater productivity, and they let the carriers slash each other's throats in a discount war for that shippper's business.
Did it ever occur to you all that shipping is undervalued in this day and age, because of overly fierce competition? And who is paying the price for that?
You and me, that's who.
You say that carriers would have to pass on the costs of increased wages and benefits, and that may be. Or maybe... just maybe... some of these carriers would have to stop handing out 70% discounts (which is industry average these days, and ask any salesman if I'm wrong) and start asking their customers to start paying full tariff rates.
I think that you might see some truckload carriers try and get into hauling more LTL if the LTL carriers start getting more expensive, but that may not work very well in this day and age when even the best-paying carriers are finding it difficult if not impossible to find good, qualified drivers or even just warm bodies to fill their trucks.
Hey, that ain't Swift I'm talking about, either. I'm saying ABF... Yellow... FedEx Freight... ConWay... they are all having difficulties in recruiting. The average driver shortfall is now reaching crisis proportions, so there is already market forces at work bringing pressure to bear to drive up wages and bennies.
My point has always been that the union is a market force, and a rising tide lifts all ships... to one degree or another. But the more carriers that are unionized or pay union-level wages, the more leverage the companies have in attracting and retaining drivers, which is a HUGE concern amongst all carriers right now.
Freight don't move without drivers, I don't care what you pay or what discounts you give out.
You can't really draw a direct comparison betwee auto workers and truckers, because one is about manufacturing a product that can be built more cheaply elsewhere versus a service industry that has a high bar madated by the government to reach in driver standards and safety.
Competition for drivers is for the forseeable future going to be a far bigger driving market force than unionization amongst all sectors of the trucking industry.
Our time is now, so let's use the leverage we have while we have it...
