What honeymoon may have existed between Walmart and D.C. officials seems to be over.

The mega-retailer—which is set to open six stores in D.C., the first two later this year—is among a number of opponents to a proposed bill that would force national retailers with stores larger than 75,000 square feet and annual revenues of over $1 billion to pay an hourly living wage of $11.75 and offer benefits, reports the Post.

The bill was introduced by D.C. Council Chair Phil Mendelson and is backed by 11 of his colleagues. In the text of the legislation, it notes that more and more D.C. residents are taking job with large national retailers and that “by adopting living wage standards for large retailers, the District can ensure that economic development better meets the community’s need for family-supporting jobs.”

As part of its opposition to the bill, Walmart has played a role in setting up a website and encouraging people to testify against the bill when it is considered by a D.C. Council committee next week, said spokesman Steve Restivo:

Despite its corporate backing, Restivo said, the group is mobilizing a crowd “representing a variety of age groups, ethnicities and business interests” to oppose the bill. Wal-Mart itself, he said, will submit written testimony opposing the bill and representatives may also testify in person.

“We expect a really strong showing from the community Wednesday” at the hearing, he said. “Actions that seek to block economic development are misguided, especially at a time when unemployment is still in double digits in some place and residents are still spending a billion dollars in the suburbs.”

This isn’t the first time such a measure has been considered by the council—similar bills were introduced in 2005, 2007 and 2011, but never went anywhere. The minimum wage in D.C. is $8.25 per hour.
