When thinking about credit unions for which the place of employment is the common bond, prior to the trip I'd mostly bought into the assumption that they essentially fulfilled a human resources function for employers. While the credit union I wrote my Masters thesis about was founded by a labor union, I'd assumed it was an anomaly, and that most employer common-bond CUs were rooted in a certain level of employer paternalism.
However, as my trip progressed, it became increasingly clear that the significance of the role played by labor unions in at least African American credit union history, and possibly the history of credit unions more generally, has been distinctly under-recognized. Upon reflection, I believe that this is partly the fault of the fact that the most easily accessible documentary sources from the early movement, such as many of Roy Bergengren's books, were often promotional materials aimed at convincing employers to offer credit unions free space in their facilities, and thus played up the human resources angle.
However, a theme that emerged in many of the interviews I conducted over the course of my trip was the important role played by labor unions in both the establishment and governance of many of the credit unions I encountered. To start with, my very first interviewee, Milton Carr, was not only the former president of the Arabi Sugar Workers FCU, but had also been a union officer prior to his retirement. One has to be a member of the union at the plant to join the credit union, and he was quite explicit about the ways in which the credit union benefits the bargaining position of the union by contributing to the financial stability of the members, as he lays out in the following clip concerning his credit union's "strike fund" savings program:
