There are the ‘givers’ of the world and the ‘takers’. Givers are generous and caring, trying to do their best to return a piece of karma to the world. Takers are a different story– If you give an inch, they'll take an entire yard.
Managerial hubris is one of the reasons employees hate their jobs. Not only are we lacking in pay, but we are enslaved to the most incompetent group of overinflated bimbos who could easily be replaced by AI– at leas the replacement would be more charismatic. But these types of managers will deny your raise and then come begging for your help. Which is it? Do you value my hard work or not?
