You are the human resources manager for a boutique retailer. Currently, the company pays the sales staff a flat $18/hour for each 8 hour shift, regardless of sales. You suggest an alternative compensation scheme in which sales personnel receive $8/hour for each 8 hour shift plus .005 times the store's daily profits. Marketing research suggests each store could produce $40,000/day in profits. What points would you emphasize to persuade senior management to adopt your new plan?
