BENTONVILLE, Ark. — Wal-Mart Stores here has reportedly filed a lawsuit against the United Food and Commercial Workers Union and an affiliated group, charging disorderly conduct in Los Angeles-area protests late last year.

According to the suit, the West Coast actions by the UFCW and the Organization United for Respect at Walmart (OURWalmart) triggered demonstrations against the company in other cities. According to the reports, the lawsuit said the two groups engaged in disruptive labor activities, even after Wal-Mart asked them to cease and desist. The suit accuses the groups of trespassing, confronting store managers and blocking customer traffic.

Wal-Mart filed a similar lawsuit in Florida against both groups earlier this year, accusing them of breaking state law by coordinating trespassing activity at stores in the state.
