A labor union doesn't think Walmart is closing stores for plumbing problems.
The Food and Commercial Workers Union thinks Walmart, at least in some cases, is retaliating against workers who were trying to get better pay and working conditions, according to a story on Reuters.
The union is trying get the National Labor Relations Board to intervene and get the workers re-hired somewhere else.
The Walmart store at Admiral and Memorial in Tulsa is one of the stores that were closed for what the chain said was plumbing issues.
