I work for Walmart. Our store alone brings in over $1 million a month in profit on the off-season, we bring in over (estimated since our sales more than tripled) $3 million a month on the holidays. In August, we were making over $380,000 in sales per 24 hour period. We have 500 employs, many of them are working less than 12 hours per week first period, the overnight shift is the only one with consistent hours which is also put on an understaffed skeleton crew. So our 500 employs operates more like about 200 full timers, probably few than that. But even if the 500 employees all worked full time hours, the company still made over $24,000 per employee profit per year, the fact they are part timers means they made even more than that on the average.
