Open Question: What benefits are given to part time employees of Wal-Mart?

I have seen the full list given to full time employees. I was just wondering how the part time benefits differ. Do part timers receive the same stock options? Thanks In Advance! I'm not looking to be employed at Wal-Mart, I was just browsing and couldn't find the answer. I just sparked an interest regarding the differences in benefits considering they hire most as part timers. Thanks!
