How can I get her to miss me?

You can't MAKE someone miss you they have to MIS you on their own. Well, her own. If she likes you enough to want to be around you when your not their she'll miss you that's why I miss something I generally WANT repeat WANT be around that thing again to miss it. Focus on GETTING TO KNOW HER, and don't stress on this help her have a good time in your presence bring her something that no one else does when your around and she'll defiantly miss that.

Ok the problem is this seems to me that she's not that into you, that's why she doesn't call you, and if someones not into you then its impossible for them to miss you. Good thing here though is you work with her, ok now you gotta turn up the heat on this chick, when you see her don't act weird, don't say things like why haven't you called me, but what you need to do is flirt with her, like your interested in her, examples tickle her, make fun of her in a nice way, touch her. And then ask her on a date if you already haven't. That could be why she doesn't miss you, because she has no idea your interested in her.

Listen to all those people if you want to end up in the friend zone hahahaha.
First off, why would you want a girl to miss you? I'm going to answer this as if you want the girl to be interested in you.
You need to flirt with her for a couple of days that you see her at work. Don't do it while working. Do it while on break or after work. While working you should be be all business and pay little attention to her. So the first week, you flirt. The next week you don't talk to her unless she comes to you. Keep your chat short and say you are in a hurry and get out of there. If she has any interest in you, she'll be confused and wondering why you are acting as you are.

Seems you don spend a good enough time knowing bout her. To come up with the question.

In the 2-3 times you spend with her at work try being intimate on things she adores, step into her boots to see how she feels herself in the work environment. Maybe talking round you is just part of acting professional. Keep your talks simple yet meaningful, come up with some jokes that only you two share. Next time you meet a mere movement of hands might make her remember the joke. And if you can make her laugh. Then definately you are someone she would try remember in her day.

You have not mentioned the depth of relationship you guys share.

I would initially go more by how she behaves toward you away from work. How she acts on the job right now may be more a case of not needing everyone there (especially management) to know your business. An exception would be if she's more concerned about what other guys there know about you two. Body language usually reveals much. How does she act around other guys at work? Does she spend a lot of time joking with them and playing with her hair? Then around you she acts somewhat cold and serious?
