Critics of Wal-Mart who oppose the retail giant’s plans to expand in Rohnert Park are fighting an uphill battle, especially on labor issues, warns a University of California historian who has studied the company.

Knowing they will face local opposition in many communities, Nelson Lichtenstein (left) observes that Wal-Mart has recently turned to a new tactic to minimize the regulatory review they must undergo—moving into existing but empty big box buildings.

That didn’t work so smoothly for the company in Santa Rosa, but the vacated space next to the already-established Wal-Mart in Rohnert Park apparently prompted their bid to expand into it.

In his recent book, The Retail Revolution, Lichtenstein charts the history of Wal-Mart from its origins in Arkansas and Alabama, detailing how the attitudes of founder Sam Walton became enmeshed into the core culture of the company. And, he says, they didn’t change as the retailer expanded and grew, and now lie at the heart of many of Wal-mart’s battles with local communities.

Opposition to the proposed Wal-Mart Supcercenter in Rohnert Park (seen here in an artist's drawing of the project as it might look) is being led by the Living Wage Coalition. The city's planning staff has recommended approval of the Environmental Impact Report for the expansion. Read the full staff report here. The city's original approval for the store in 1991 allowed the store to occupy up to 225,500 square feet; is it currently using just 131,500 square feet, and the proposed Supercenter would increase that to just under 178,000 square feet.
