There are positive jobs and then there are double-negative jobs.
Positive jobs when done well increase the revenue of the company. On the other hand, double-negative jobs when done well, prevent the loss of revenue. Consider HR, lawyer, physical/information security personnel, all are double-negative roles. If they do their job well, you won’t notice any harm. It is hard to justify spending on double-negative jobs. They don’t increase the bottom line. The shareholders question the spending. But when they don’t go well, you end up with huge losses.
