Friday won’t be the first time an Obama holds an event at a Walmart store. Last year, Michelle Obama took her “Let’s Move” message to a Walmart produce section in Springfield, Mo., where she “disgusted” some citizens who consider Walmart “the single biggest thing wrong with America.”

The president himself is feeling some heat for his planned stop at a California Walmart to speak about energy efficiency. United Food & Commercial Workers Union president Joe Hansen is urging President Obama to speak with Walmart workers about their struggles.

In a statement, Hansen said that on Friday, “President Obama will stand side by side with a company known for low wages, few benefits, unreliable hours, discrimination against women, violating workers’ rights, and yes, environmental degradation.”

Protesters are getting a head start on their signs.
