1) engineers should get a similar form of compensation, in my experiences 'bonuses' don't come anywhere close to what commissions do.
2) how can sales get commissions AND a salary. should be one or the other
3) commissions incentivise sales to sell ANYTHING they can get a commission on, not necessarly the things you want to sell or are good at making. one needs to be very careful in what sales is allowed to sell.
4) how can a product or service be returned or canceled and the commission still paid! insanity! no clean sale and the corrections fall through the cracks...
yeah... I'm a little bitter.
