Long story short, my immediate supervisor had an accident two months ago. He has been on leave for the past two months and I've been the acting manager of the department ever since.
The directors for the department offered me the interim manager title since I'm already doing the work but HR said no because I apparently lack experience.
So, like almost always, all the work and responsibilities but no pay to match.
HR has also been holding up an approved pay rise for weeks now.
** the interim title is an actual title that comes with higher pay.
