When I worked in the grocery industry, it was interesting to see the difference between a non-union company and a unionized one. Part of orientation for the non-union company included a video explaining the dangers of unionizing. For the workers, the unionized company was far better but I'm not entirely sure it wasn't also better for the company. I worked in multiple stores for the non-unionized chain and employee theft was extensive, even with the managers. I never saw that at the union store. Same for caring about their work. One employee screw up can cause tens of thousands in merchandise losses. It's worth noting that the non-unionized chain grew to be one of the largest in the country but now is on the verge of being erased from existence. The unionized chain lives on as part of the Albertsons conglomerate. Also worth noting that the unionized employees generally had negative feelings about the union but most had never worked for a non-unionized grocery.
