This is similar to a manager and boss situation. The boss wants you to argue you value, you suggest a 20% increase in salary and the boss shuts it down with 5%, your manager then explains to the boss how good you've been and that you deserve more. Your boss nods his head and turns back to you, you now want 15%. Your boss insists on 10% but your manager then intervenes and suggests 12%. You think your manager was still on your side, the boss agrees. Everyone is happy.
Really? You've accepted a 12% increase in salary for double the work. Congratulations, you just got played and fucked lubeless by two higher ups.
