Pros: steady hours, potential for bonuses
Cons: low morale, favoritism, no challenges
I tried working on both ends of the West spectrum (customer service and then sales), each for about a year and a half. Both times I was more or less driven to find a new job by the lack of attention on the part of management. There were a few managers who obviously picked favorites, and almost the whole time I worked there, there was little employee morale because of this.
I worked extremely hard, was successful at my job as far as I could tell, and interviewed several times throughout 3 years trying to advance, but never got the opportunity. Once, a manager even congratulated another associate who got a supervisor position right next to me, and I heard her tell the associate she has "said everything perfect." I've also overheard some nasty comments made by managers about employees' "orientation" and appearance.
THAT being said, the hours were nice. The pay was appropriate, with opportunities for bonuses. This is a good starting point, but unless you're willing to turn the other cheek, don't expect to climb the ladder quickly here.
