> What about flat companies?

I also work in a flat company. Actually some weeks ago, one of my colleagues was applying to a new credit card. So the bank called our HR team to very a colleague's salary. I ended up taking the call due to a mishap on the phone system. So they needed to double check her salary, because she had mentioned 50% raise but no change in her job title. So I had to explain that's the way our company is.

Same problem here... small company, everybody does everything, same title, but different hours and output. I guess we'll have to think of unique position names for everybody
