Every sales job i have been in was either full commission, base+commission or draw/commission.
The only time i was ever paid vacation was when i was base+commission.
Sales, you do not call in sick. You work your tail off 5-6 days a week 8-12 hours a day. You can take vacation when you have put in your time and move up to management. Still even then when i was in management i never took vacation or sick time.
you take time off, you lose out on sales. A real salesman hates missing a sale.
