When you work in a cost centre, the company expects you to work more for less. And nothing more. Obviously, they try to make you feel evil, you should start any conversation with “I am sorry for spending your money, but that’s what we do in a cost centre”. When the sales reach their goals, they are praised and called awesome, when we reach our goals, we are “just doing our job”.
It’s not something to feel bad about, one just needs to understand this and not feel bad for a seeming lack of appreciation.
The fact, that you prevent the company from getting into huge trouble that may cause million of losses, does not matter. It’s your job, right?
