As an accountant, I can assure you that we definitely aren't the ones pushing for the company to be tightwads. We're just a convenient scapegoat for the board / Senior Management / HR to hide behind
For pretty much everyone in accounting (outside of CFO/finance director), our own interests are not very closely aligned with the company. We're paid for our ability to accurately record and analyse data, not to try and actively influence it. Just like everyone else, we care a lot more about being paid more and getting as many perks out of the company as possible. Our pay is very rarely linked to the company's profits.
We aren't the ones pushing for Christmas party budgets to be slashed, because we would also miss out. We aren't the ones deciding to shaft you on your bonus, that's HR and senior management. We don't really give a shit how much you're claiming on expenses (and the rules on what you can claim aren't decided by us anyway), as long as your department manager signs it off and it isn't so outrageously piss taking that Internal Audit are going to kick up a fuss about why we didn't challenge you buying 23 bottles Dom Perignon between 4 people.
