A colleague is leaving and my manager is trying to increase my responsibilities
I'm working at a tech company and a colleague from my team is leaving the company soon.
My manager wants me to "wrap up" my current responsibilities asap because they need my "support" in the other project until they hire someone else to replace the colleague. They frame this as "helping them".
My schedule is already super packed and I already have some additional responsibilities on top of my current role. Adding more responsibilities and dividing my focus in two completely different projects is not feasible and honestly I really don't want to do it without any additional compensation.
How should I navigate this?
Additionally:
Last time someone left my team, upper management acted like they were looking for someone new but at the end another colleague took over the extra responsibilities no one was hired. I don't want same thing to happen here.
Also sorry for any grammar mistakes. Im super nervous and dont have the mental capacity to think properly in another language.
I dont want to be recognized so Im skipping some details. I can share further details if someone would like to provide guidance. Thanks
