(WCMH) — Walmart employees are expected to walk out in protest of the retailer’s gun sales policies Wednesday afternoon.

The Washington Post reports hundreds of workers at Walmart e-commerce offices in California, Portland and Brooklyn are planning to walk out at 3 p.m.

The walk out comes after a gunman opened fire in an El Paso Walmart Saturday, killing 22 people and wounding dozens. Last week, a Walmart employee shot and killed two co-workers at a store in Southaven, Mississippi.

Organizers started a Change.org petition calling on Walmart and the retailer’s president and CEO Doug McMillon to “cease the sale of all firearms and ammunition, ban the public open and concealed carry of weapons on company property and in all stores, and cease WALPAC donations to NRA backed -A/A+ politicians.”

Last week, our Walmart family suffered two separate acts of violence. It’s difficult to find a word strong enough to describe the way we feel. We’re feeling a range of emotions – shock, anger, grief. We also feel gratitude for the first responders in El Paso and Southaven and are proud of the way associates reacted so courageously. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ I’m in El Paso today, and I’ve met heroes. We heard incredible stories of associates who made heroic efforts to get customers to safety. From our manager, Robert, who was leaving the store then ran back when he heard shots, to Gilbert and Lasonya, who helped dozens of customers to safety out the back of the store, to Mayra, who may have been the very first responder, and did an exceptional job bandaging wounds and helping customers escape. I also got to thank Sarah and her team from the Sam’s Club next door for the care they provided to customers. We heard story after story of courageous associates putting others ahead of themselves. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ When the worst happens, we counter with our best selves. We support each other, pray, stand firm and heal together. We’re proud to be woven into the American fabric as a place for all people, a community gathering place. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ As it becomes clear that the shooting in El Paso was motivated by hate, we’re more resolved than ever to foster an inclusive environment where all people are valued and welcomed. Our store in El Paso is well known as a tight-knit community hub, where we serve customers from both sides of the border. I continue to be amazed at the strength and resilience we find in the diversity of communities where we live and work. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ We’re a learning organization, and we’ll work to understand the many important issues arising from El Paso and Southaven as well as those raised in the broader national discussion around gun violence. We’ll be thoughtful and deliberate in our responses, and will act in a way that reflects our best values and ideals, focused on the needs of our customers, associates and communities. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ Thanks for what you do every day, especially during this difficult time. I’m grateful to be part of this team and proud of you.

Walmart spokesperson Kory Lundberg provided this statement:

“There are many more constructive avenues for associates to offer feedback, such as email or leader conversations, and the vast majority of associates who want to share their views are taking advantage of those options.”
