Alright;
Now we have some of the excuses, and some of the history, and hope that everyone knows that it does not have to be IBEW, again I ask why not organize?
FWIW, take a hard look at the travelling crafts, in the north, they are all organized and play shop lines/work division strictly.
Take the Millwrights, the boilermakers, the carpenters, the laborers, etc. for the most part they are all organized union workers!
There is no reason why HP rent a techs, deconners, etc can not be organized. The motto is organize or die!
I do not think we need long winded discourses as to the benefits of being represented by a union, and there is no doubt that there will be growing pains. Hell if the migrant farm workers in California organized years ago, (some with questionable immigration status), again, there is no reason why road techs can not organize. It just takes collective action, and I assert that now that there is only a handful of contract companies that it would be easier now than in the past.
As for the plants recognizing a union, legally they have no choice in non-right to work states, and one of the major goals of the AFL-CIO is to organize unorganized labor, so there are resources available.
... for now
