Kroger faces massive worker walkout, closed stores
One of the grocery giant's labor unions has authorized a strike which follows a similar vote by Teamsters.
Labor problems tend to spread like a virus once they take hold.
Starbucks has seen that happen as one store unionizing slowly led to unions forming all over the country. You can argue that those issues at least partly caused multiple CEOs to lose their jobs (although there were other reasons) and created significant negative publicity for the company.

In addition, over the past few years pretty much every airline has dealt with labor unrest from its pilots and flight attendants. That led to threats for strikes, although no actual work stoppages, and ultimately large raises for pilots and more moderate ones for flight attendants.
Even the threat of labor unrest hurts a company. Airlines have more protection as workers need federal permission to strike.
Grocery stores have no such protection giving workers a lot of leverage.
