My ex-wife retired from Walmart, for her, it was a decent job, she quickly rose from greeter to department manager, (she had been an assistant manager at a Burger King prior) pay scale & benefits escalated quickly to, because of her quick advancement, other employees didn't like her much. Even after we were divorced, she gave me her extra employee discount card. Saved me a ton of $$ when I opened my new office
But, being a grunt in the auto dept at Walmart probably isn't a place for quick advancement unless there is high turnover and the dept manager is nearing retirement
