Believe it or not, that's actually a good thing. Ready reserves are the absolute last option for getting a flight out (outside of JM). The company would much rather use a long-call reserve when possible than have to burn an airport reserve. Sitting reserve and not getting called gets boring, but it's part of being junior. Just about all of us had to do it. At least you're getting paid something. I've had week-long stretches of home reserve without getting called, which means I credited NOTHING for being tied to my phone all day.
The good news is, over the course of your career, you'll do a lot more line-holding than you will reserve-sitting.
