Most unions in the US are associated with their particular trade, not a particular company, as far as I know. There is SEIU for service employees, UAW for auto workers, USW for steel workers, etc. In addition to these, there are federated organizational bodies such as the AFL-CIO and Change To Win which determine certain union strategies/positions. I don't understand why you draw a distinction between "white collar" and "blue collar" labor. All wage labor is fundamentally about an individual or small board of directors dictating the terms of production for everyone else. The Board then makes all the decisions about what to do with the output of that production, and what to do with the profits which come from selling those outputs. Under the current economy, workers have no right to make any of those decisions, which are critical to their lives. Wage workers should not be divided as 'blue collar' and 'white collar'. Instead, they should be united against this system of wage work. Their interests are the same: shorter hours, a better standard of living, and more personal autonomy.
