I am have recently started a new role at work- it's a sideways move in same team, at same grade and same pay. The job was advertised with no line management responsibility.
I am now being told that I will have to line manage 2.5 staff. No increase in pay. No other person on our team at same grade as me line manages.
Line management is the only thing that differentiates my grade and the next grade up.
I don't mind line managing people, I have done it before. However, I do feel it is unfair for them to
a) change specifics of my job role
b) get me to take on more responsibility without an increase in pay.
What should I do? I have spoken to the Head of department who was trying to fob me off.
