to be honest, i do the budget and forcasts, but i don't suppose to know the individual's salary. then even you know others have higher salary than you after you manipulate the number, you should not be voice out to your boss regarding to this. or discuss this with other people as this is your work ethics to keep those budget confidential.
for yr info, my current n previous companies budget, actual staff cost means NOT only base salary but also "provision of year end bonus, provisiob of incentive bonus" as well as others like MPF, medical insurance, allocation cost for misc general benefit. And there will be round up in the dept file. We round up to kUSD.
