Having worked for Sears in the 70s and 80s, I'd say it was better. You could actually MAKE MONEY working at Sears, I even knew people who survived on part time in some departments. Employees got commission and employee discounts. We got profit sharing, imagine that. We accrued a pension. We got time and a half on Sundays.
We still complained--retail is not fun no matter where you work, and I actually hated my job, but I made at least a decent living--but I met some of the best people I've ever known working at Sears.
But when Kmart and Walmart passed Sears, the higher-ups got frantic, trying various strategies to get back their mojo. Cost cutting became a quick fix, buying all the financial properties was a distraction, etc. After the early 90s, when they got rid of anyone who knew their posterior from a ho-e in the ground, things got worse (but hey, minimum wage workers can do the job just as well, right?) When employees are considered to be costs instead of assets, you know you're in trouble, and Sears went that way.
