Wal-Mart is the largest private employer in the U.S., and has 2.2 million employees around the world.
But at least a handful of those workers say they've lost their jobs for insane reasons.
One employee claimed she was let go for saving a puppy, while another tried to fight back against the Black Friday masses and lost her job.
Other employees were supposedly axed for less noble pursuits.
For throwing around iPads and posting a video of it online.
Walmart fired employees at a Kentucky store who posted a video of themselves throwing and dropping boxes containing iPads in the storeroom, according to NBC News.
"Hope nobody buys that," one said.
Walmart said it was embarrassed at the behavior, telling NBC News, "It made us wince."
For stopping an armed robber.
Walmart supposedly fired four employees who managed to disarm a robber at a Utah store, according to the Consumerist.
The thief was allegedly trying to steal a netbook, and when the employees confronted him, he pulled out a handgun.
Walmart policy states that employees are required to "disengage" and "withdraw" if a customer presents a weapon.
For praying with a crying customer.
A pharmacist sued Walmart for religious discrimination, claiming she was canned for praying with a customer (and getting caught on camera).
The video supposedly showed the pharmacist touching the hand of the customer, who was crying, according to ABC News.
The employee said she was merely helping a patient, not praying. But she did not dispute that she prayed "with customers when requested to do so," ABC reported.
