A spokesperson for Walmart says it will soon revamp its policy so that employees can use paid sick days starting on their first day out. The spokesperson added that its bonuses, 401(k) plan, and health plan are considerably better than at most other discounters—its 401(k) plan gives a dollar-for-dollar match for the first six percent of pay and the premium for its most popular health plan is just $21.90 every two weeks. That said, part-time workers, who represent nearly half its work force, don’t qualify for many of these benefits.

The leaked video also boasts, “There’s no retail company that offers more advancement and job security than Walmart.” Considering that some retailers are unionized with strong job-security provisions in their union contracts, some labor advocates wondered how Walmart could begin to assert that its job security is as strong as any other retailer’s.

“That’s patently false,” said Stuart Appelbaum, the president of the Retail, Wholesale and Department Store Union, a division of the UFCW. “At Walmart you can be fired for any reason at all or no reason.” He contrasted Walmart, one of the nation’s many “at-will” employers, with retailers that are unionized or partly unionized, including Costco, Macy’s, H&M and Modell’s. At unionized stores, workers can only be fired “for cause,” meaning managers need a strong reason to fire someone—for example, stealing from a store or arriving 30 minutes late five days in a row. Moreover, workers in those unionized stores can usually challenge their dismissal by bringing in an impartial arbitrator who helps determine whether a firing was justified.

Walmart, in its orientation video, makes other attempts at belittling unions. It features an actor who says, “I was a union member at my last job. Everyone actually had to join the union . . . The thing I remember most about the union is that they took dues money out of my paycheck before I ever saw it, just like taxes.” The character’s assertion that he “had to join the union” diverges from the truth. The Supreme Court ruled in 1963 that workers cannot be required to join the union at a unionized workplace—although they can be required to pay union dues or fees (unless they live in one of the 25 states with “right to work” laws).

In the video, an actress standing in front of a rack of produce continues to hammer the message. “I always thought that unions were kind of like clubs or charities that were out to help workers,” she says. “Well, I found out that wasn’t exactly the case. The truth is unions are businesses, multimillion-dollar businesses that make their money by convincing people like you and me to give them a part of our paychecks.”

Although some union leaders have generous salaries, Benjamin Sachs, a labor law professor at Harvard, said that unions aren’t for-profit businesses. “If unions are businesses, they’re the best example of the sharing economy we’ve seen,” Sachs said. “Here’s the business model: By sharing their resources, including their financial resources, workers make better lives for themselves and their families.” Thomas Kochan, an MIT professor of management, said that the phrase the actor uses—“clubs and charities”—“insults any new hire’s intelligence.” “Most people know what unions are and what they try to do,” Kochan said.
