Having worked in General Sales for the bulk of my career here, I have a lot to say about it.
-The pay is abysmal if you work in General Sales. I wish I was exaggerating. Having worked there, I can suggest that GS associates need to be paid hourly, with incentives to sell things like service plans and such, instead of being strictly commissioned with a $4/hr base rate. The workers there were literally competing for the sales of low-price items, like $2.99 audio adapters, while every other sales department (Systems, Apple, and Build-Your-Own) sold thousands of dollars of merchandise regularly.
-General Sales associates are also tasked with unloading the merchandise truck and stocking the shelves, all while being paid the same $4 an hour while being expected to sell. In addition to being the main merchandisers, they are expected to clean the shelves, dust, sweep, and vacuum, in addition to selling. As much as Micro Center loves to claim the moral high ground against Fry's Electronics for being a more ethical workplace, at least Fry's assigns its salespeople to earn hourly pay for doing manual-labor in place of selling on given days of the week.
The environment of Micro Center is good, but the actual logistics of selling and handling customer's requests needs to be reworked. Salespeople are effectively punished on days that there is low traffic. Managers tend to play favorites with the staff, but this is natural of any workplace.
