Wal-Mart suddenly closed 5 stores and laid off thousands of workers and no one knows why

Wal-Mart suddenly closed five stores in four states Monday for alleged plumbing problems.

The closures could last up to six months and affect roughly 2,200 workers in Texas, California, Oklahoma and Florida, CNN Money reports.

Wal-Mart employees say they were completely blindsided by the news, having been notified only a couple hours before the stores closed at 7 p.m. Monday.

"Everybody just panicked and started crying," Venanzi Luna, a manager at a Pico Rivera, California store, told CNN Money.

All workers will recieve paid leave for two months. After that, full-time workers could become eligible for severance, according to CNN Money. But part-time workers will be on their own.

Local officials and employees have questioned Wal-Mart's reasoning for the closures.

According to ABC News, "no plumbing permits have been pulled in any of the five cities where the stores were suddenly closed for at least six months."

A city official in Pico Rivera, California confirmed to CBS Los Angeles that the city has not recieved any permit requests for building repairs.

In Midland, Texas, where another store was closed, a city official told ABC News that his plumbing inspector was turned away when he visited the store and offered to help secure construction permits.

Wal-Mart plumbing technician Codi Bauer, who worked at the now-shuttered Brandon, Florida store, questioned the company's timeframe for the repairs.

"Even if they had to replace the whole sewer line, it wouldn't take six months to replace a whole sewer line in that store," he told WFLA.

We reached out to Wal-Mart for comment and will update when we hear back.

A Wal-Mart spokesman told Consumerist that the company had not secured permits "because we have yet to know the full extent of the work that needs to be done. We may also have to do additional upgrades that may require additional permits."

Some employees believe that the stores were closed because of worker protests for higher pay.

Employees of the the Pico Rivera store were among the first to hold Black Friday protests in 2012.

"This is the first store that went on strike," an employee told CBS Los Angeles. "This is the first store in demanding changes for Walmart."
