What's the best way to ask my IT manager for a first year review? What's the best way to approach it from a junior position where I feel I'm being underpaid and overworked?

I’ve used this https://iwillteachyoutoberich.com/g... and several other courses from Ramit.

First of all, you should be getting continuous feedback via monthly one on one sessions. If that isn't happening, you need to take the initiative and schedule them. Secondly, just ask. Ask about what you are doing right, and what you could improve on. That shows you take your work seriously, and you want to improve. It also lessens the chance of being blind sided by a poor rating. Semi-annual and annual feedback and ratings should be documented in writing.

Update; went ahead and asked the new IT manager. I'm scheduled for review. My work will speak for itself, but I'm prepping hard for what I'll say.
