What percentage of walmart employees are part time?

Question

This article enclosed from two years ago says that they deny that 40% of their employees are part time. A lot has happened since then and I could only imagine that it has risen. If you are making an educated guess, then please mention an educated guess and a brief summary why. Thank you

No employees at Wal-Mart actually work.
