mylalynn,
Junipers are one of the least appropriate species for any type of indoor culture, a desk at work is a very poor situation for a Juniper. Look here for some tips on Junipers.

This is a direct quote from that article, emphasis mine:
Never try to grow Junipers indoors, though they may seem to tolerate indoor cultivation at first, poor humidity, lack of light and dormancy will eventually kill them. Do not trust a vendor, seller, book or website that claims Junipers can be grown successfully indoors! Dead Junipers can continue to display normal foliage colour for weeks or even months after they have effectively died.
The fall from the desk may have been "The straw that broke the camels back" The other Juniper will eventually weaken and fail as well. If either is lucky enough to survive until next season they should be placed outside and remain there.
