The back story, for those like PESMES that don't keep up on current events, is that the City of Long Beach (that's in California, again for those that don't know) ordered grocers to pay their employees an EXTRA $4 an hour on top of what they were already making as "hazardous duty pay".
So, Kroger (the parent company) said that it makes more business sense to close up shop.
They WERE supporting their workers before the city tried to see who could pee further. Kroger won.
Now, the workers aren't making squat, except possibly more on unemployment than they were working.
Business not only need to support their workers, but they also need to support their customers and shareholders. Shareholders need to see a profit. If expenses go up, management is not going to decrease their profits, they'll just pass on those expenses to the customers or, as in this case, stop the non-profitable activities.
