One word - scheduling. There are times when hardlines will have 8 people in the morning but only 2 in the evening (and there is scarcely anyone in softlines, resulting in piles of reshops in front of the fitting rooms - which I'm sure looks absolutely wonderful to the customer). There are times when there is no one scheduled as a mid-shift customer service supervisor, meaning that the opener and closer need to scramble for coverage on lunches and breaks, because if we don't take them, we get written up. Some members of management are downright hostile to the customers, after we call them for help with an issue, thereby making the service desk staff look both vengeful and incompetent. Staff can be cranky and snarky with customers at times, as well as with some of their coworkers, resulting in a sometimes tense work environment.
The computer system is in DIRE need of updating, and ARMS needs to get their act together and actually head out to a location when a service call is put in - my location has had a register out of service since just after Thanksgiving, and no one has shown up to repair it yet, despite repeated calls.
Dead weight is almost never eliminated, while great employees consistently seem to find their way to the wrong side of the revolving door.
Pay is virtually non-existent, and is in no way competitive with other big box retailers.
Advancement is next to impossible, unless you have the ear of someone on the management team or kiss their asses on a daily basis.
The daily on-call sheet is more or less useless, as it seldom if ever matches the posted schedule downstairs, leaving us to guess who's coming in to what department and at what time.
Any dealings with HR are horrific at best.
