At Thoughtworks, we've considered removing commissions

We had been thinking about doing this for ages - it just didn't seem right in our culture despite the industry driving everyone towards this especially on the sales side. We were told that we would not be able to find the best candidates (some said we would not find any candidates), we were told that everyone in sales would resign, we were told it was the biggest risk to revenue we had ever taken. -- Trevor Mather, CEO

but our concern was

if we get rid of sales commissions...

...will we be able to attract and hire good salespeople?
