The UAW is touting its strike resolution with GM as a victory and a model to be used against [sic] Ford and Fiat-Chrysler. A letter writer to The Wall Street Journal has pointed out some other aspects of the union’s most famous victory.

For every GM employee at an assembly plant, there are at least 30 working at suppliers providing parts, materials, and services to those plants.
…
During the strike almost all the tier suppliers were forced to shut down or seriously curtail their operations, meaning layoffs (union and nonunion alike). Many of those employees must seek other employment….
…
the [suppliers’] employees who do go back to their jobs will simply go back to work with accrued lost wages and benefits incurred during the layoffs. Those suppliers will also have to go out, recruit and train new employees to replace those who left and don’t return, adding to their costs.

But, hey, UAW management got theirs.
