(Following is not in accordance with standard horary practice and uses whole sign house format)
I'll assume that the OP wants to know if the co-worker has sexual attraction/desire and interest of this nature, in the OP, so I'll use the Part of Sexual Attraction to estimate an answer to this question:
I'll use the "generic other" 7th house, to signify the co-worker; and, in using the Part of Sexual Attraction, I'll use the quesited's (co-workers) "ascendant" which would be the cusp of the 7th house:
-querent = 1st house = Cancer = Moon
-co-worker = 7th house = Capricorn = Saturn
-co-worker's Part of Sexual Attraction (POSA) falls @ 11 Aries
-co-worker's significator Saturn retrogrades away from the POSA = no
-querent's significator Moon is in square to the POSA = no
-dispositor of the POSA, Mars, flows away from co-worker's significator Saturn (which also retrogrades away from Mars) = no
-additionally, co-worker's significator Saturn retrogrades away from querent's significator Moon and Moon also flows away from co-worker's significator Saturn, and Moon/Saturn are in seperating aspect = no
In my opinion, the answer to this question is "no" (at least as of the present time)
However, querent (Moon) does flow toward the co-worker's POSA, and toward Mars (dispositor of the POSA): so, I would say (if you are interested in the person) yes you should go and say hello the next time you see her!!
