Don't feel like i am secure at my job
I recently graduated college and have been at my job for about a year, it is an IT job. I don't feel like I do much here. It is a sort of 'learn as you go/need to' type thing and I have someone I work directly with but we rarely talk or see each other. I get assigned to do things and then through the course of completing the work there are long pauses, like days, that I try to fill with learning more or just doing whatever I can to not feel like I'm completely wasting time. I got a bonus that I have to give back if I get fired or quit within a certain period. I don't plan on quitting at all because I do like it here. I just worry about getting fired because I'm not doing anything useful and my bills plus the bonus add to the stress of getting fired. I have had a couple regularly scheduled reviews already where my actual boss, who I speak to even less frequently, has said I am doing good and progressing well but I don't know if that's true or he doesn't care or he is just saying it because he is non confrontational.
Anyway, is my experience typical or should I worry about losing my job?
