This question already has an answer here:
My company was about to hire someone new. I was asked my thoughts and if I would be willing to take on the responsibilities instead of hiring this person. I told them that I didn't think they needed to hire a whole new full-time person for the job and that I would be happy to extend my role to contribute what they needed. Even though I saved the company about 40k/year I was not offered a raise for doing this. Should I have been? Should I have asked? Should I ask in a few weeks after seeing how much my work increases? Any advice would be helpful. Thank you!
