Rhys,
Youve got to establish some attraction with her. You can do this a number of ways, at work the easiest would probably be just to flirt. Tease her, be funny, tell interesting stories. Somehow youve got to put into her mind that you are an interesting person that has value. By value I mean, she would have to pursue you in order to have a chance. The work thing allows you to take things slow so just be a fun guy to hang out with then maybe try and set up a group outing for yours and her friends.
Hope this helps!
