If you're applying to any job and they either try to avoid giving you the written job description or the description says “to do what is necessary to keep the store/business running smoothly/operational” fuck that. That's just a way of dodging paying people to do more dangerous, degrading, or immoral jobs because that would mean a bump in the pay.
I worked for a whopping 2 days before being pulled to cover at least 3 other jobs that payed significantly more but they wouldn't hire anyone or just found stupid reasons not to fill the position. Sorry if it's off topic but God I hate having that thrown in my face when I don't want to go look in the tall grass for needles. Also fuck wal-mart execs and management of all levels.
