If you had to work in the back/stockroom for retail stores wal-mart or Marshalls/TJX Company, which one would be better as a career path?

Ok, So we both know about the retail stores Wal-mart and Marshalls. Both are fairly large companies that employ people. My question is, if you were to only work at one of these stores for 10–20 plus years (With no intent on going to college or obtaining a degree) then would you have been better off working in a Wal-Mart or Marshalls?

Let’s also say then for more info that you would be working in the stock/backroom and possibly expanding into merchandising or putting things on the shelves etc… but you would never really get to the cash registers (So you could still become a supervisor/coordinator but not a manager etc…)

Opinions or thoughts? Wal-Mart or the TJX companies (Who own marshalls, home goods etc…)
