Like all retailers, they have issues with availability. You ask for certain hours on certain days and at times they completely ignore it.
Be smart about where you start, as you need to really fight management to get retrained in other areas of the stores if you are tired of your own or think that it is a resume killer.
Less of an issue now, but they also used to really push the employees to sell credit cards to customers even though it was obvious the market was very saturated. One boss told me that one reason for continuing it was that hundreds of people were turning 18 every day and could apply - completely ignoring the fact that it is hardly moral giving such a dangerous thing to a youth.
The Executive Team Leader position is an absolute killer, requiring well over 40+ hours a week. One of my immediate bosses declared that he avoid being one at all cost as at least five ETL's he knew had divorces and he liked being married.
As a cart attendant, I have one of the most strenous jobs in the store requiring that I fly around acres of store floor occasionally doing numerous things at once and acting as a general troubleshooter - and have never been recognized as Employee of the Month despite years of employment. Because we are outside, apparently our work is invisible.
