everyone in the store was on commission. EVERYONE. depending on your position and department, you earned commission differently (even the supervisors and managers were on commission).

the people that worked returns got negative commission. their initial rate was based on how much the store sold, minus a % of what they returned - the harder they worked, the less they got paid.

software department shared their commission. everyone in the dept got the same amount of money added depending on total department sales.

salesmen in most other departments had positive and negative commission - commission was based on the item, not on a % per item. they pushed hard for people to not buy what they needed/wanted and instead buy the biggest commission item.

cashiers brought in a total commission based on how much money went through their register, so salesmen would bring their giant purchases to their friends instead of them getting a random cashier.

loss prevention (dude standing at the door checking receipts) got commission based on how valuable any errors were on the receipt.

enforcing an attitude of hoping your coworkers like you, hoping they want you to earn money, dont work in the same department, make tons of mistakes, and not return anything was a horrible work environment.
