It does produce a shadow, but it is very faint and thus creates an illusion of no shadow. A point source of light casts a strong shadow. As the source of light becomes larger then you end up with blurry shadow because it is made up of "lots of overlapping shadows" hence the edges seem blurry. Now in case of fluorescent lights it is large or you can say an extended light source thus it creates a faint shadow.

If you have a fluorescent tube, you can see that by holding a wide stick (maybe a cricket bat) parallel to the tube and close to the floor: now you will see a shadow as the tube is narrower in one direction. When you turn the bat 90°, so it is perpendicular to the tube, the shadow will be much less strong.

Here is an illustration:
