I don't know SwampRatt, I think the "pro" crowd has been fed small doses for a long time. Whether while on their P&D route running into other drivers at the steak n' shake, or at their P&D stops hearing "come on in, the water's great"....or the OTR driver at Loves sharing stories.
When the pendulum swings to the...lets call it the left, the group is receiving their medicine from peers in dosages and environments where it is well-received. When the pendulum swings to the "right" ;) they are getting the information in large doses from an adversary.
A bit more forcefully doesn't mean effective.
Man, I can't speak for everyone. In my case, rarely (almost never) have Union guys approached me, personally. Recently, they have offered their support, wishing us luck in the effort, but that's been it.
In the past, on the rare occasion that it was mentioned, they'd say something like "when are yall going to get the union in over there?" Again,
in the past, my reply was always "Man, we really don't need it. We have O/T after 8, good insurance, etc. Almost everything teamsters have.". Never went beyond that.
Only after the steady decline in our relative compensation, combined with excessively higher expectations (with little regard for it's impact on safety), and when I learned that this was not only at my center, but at many others, only then, did I look seriously at the Teamsters. I then did research, asked questions, verified answers and determined, that the only plausible solution to the decline, was representation. I also found that many of the things I thought I knew, were either half truths, or just plain false. To me, the potential gains offset any of the minimal downside.
That pendulum swing from the company, is tough to combat. They do have the captive audience advantage. Still, they have to follow through with the promised corrections.
