I need more money. Who doesn't

? I have been job hunting for a part time position and fell upon a federal job posting. It is for a full time position for DOL. I am considering putting in an application.
Keep in mind I have a decent job with the state now, my only concern, is it worth it to leave the job I have now?
I have a pretty good job but it doesn't pay that well. I enjoy my colleagues. We get threatened by the house/senate all the time and do not get raises unless the house deems it so. If it wasn't for getting promotions I would have never had a pay raise in the past 5-6 years!
Now we have to deal with a 3% pay cut because we now have to contribute to our pension plan. I would gladly contribute to my pension plan if I got even a 2% cola raise every year.
We must do our jobs well because performance evaluations are done every year. Lately the older employees have been advising us to seek employment elsewhere.
What do you think? Stay with the state or get out?
