Black Friday is becoming "Black Thursday," with many big retailers opening their doors Thanksgiving night.

But one Target employee is pushing managers to reconsider that decision, and thousands are joining her call.

Casey St. Clair collected more than 350,000 signatures in her online petition.

On Monday, the 24-year-old California woman delivered those signatures to Target headquarters in Minnesota.

St. Clair said she wants to defend Thanksgiving from being just another day for business.

After delivering the petitions, St. Clair told reporters, "I think they're setting themselves up to maybe next year even open all day on Thanksgiving. That's why I thought something needed to be done sooner rather than later to combat this."

Tim Curoe, Target's vice president of human resources, received the boxes from St. Clair. He told reporters his office has actually heard from both sides of this debate.

"We've also heard from a lot of other team members that they're supportive of our plans and that they appreciate and understand that they can pick up additional hours," he said. "They're excited about the additional holiday and incentive pay."

Kmart, Sears, and Walmart are also opening the evening of Thanksgiving.
