One more thing people forget to provide. Ficus, being a jungle plant from the tropics, just loves very hight humidity. Home and office environments are are dry as a desert, especially with a/c. No day to night variation of temperatures. No morning dew. No rain to wash the leaves.
In short. It can live (limp along or thrive) in your office space but give it a fair chance by providing as much of the above as you can with daily misting - morning and afternoon if you can. Keep a sprayer handy. If you don't work weekends be extra generous on Fri & Mon. Holidays and vacations must also be considered.
Bonsai, even ficus, actually need DAILY care.
