RR i am sure that everyone has had different experience with them and alot of this has to do with the number of stores they have . it's hard to get all to conform to the corp. policy on treatment of employees.
But i have also learned to take opinions of workplaces with a big grain of salt. to the slug worker anywhere would be bad. may have been cause they wanted the slug to leave.
Now it also could be job. i didnt stock shelves or cashier ....i fixed aircraft. i was seperated from the stores and would say closer to the corporate folks. so yes i may have been treated much different. but i will say that i know the intent of wal mart on paper was to care for their folks.
But the fact is prepare oneself for a decent job and you have options .
