The Reasons You Haven't Gotten a Good Raise

You Only Do What's Expected of You

You Go To Your Boss Everytime Theirs a Problem

You Don't Call Attention To Your Accomplishments

You're Not Updating Your Skill Set:  In other words, you're not staying up to date on things that would make you better at your job.  This is especially important if you work with technology.

You're Not Paying Attention To Details:  If you make a lot of mistakes, ask the same questions over and over again, or you boss constantly has to remind you about stuff, you probably shouldn't expect to see a huge raise..... or any raise for that matter.
