Ok, so now trying with the horary chart you indicated.
You asked the question, so you are ascendent.
Your co-worker is the 6th house.
You didn't say which of the two, him or her, is the one you are closer to , but from the way you present the discussion, it sounds like it is the male, and she is an "other".
In one case scenario, we have the 6th of your co-workers ruled by Saturn, and the opposing house for the "adversary" ruled by moon. So Saturn would be the male (the one closer to you personally), who is serious and sitting in his own sign minding his own business. There is also Pluto and Jupiter in the 6th, which would become incidental significators of him. Pluto authoritarian, and Jupiter expansive, young and exaggerating. Is it possible he has been acting, unwittingly, in an exaggerated authoritarian way, and that is what has gotten her back up and nose out of joint? In offices, hierarchy can be a God, and must be respected.
She as 12th house would be moon, in his 12th, working behind his back, separating from south node so not being very effective up to now. This link with south node also gives a hint of something karmic in the relationship that is being worked out now, a debt being paid from the past.
Moon moves forward and will form a weak conciliatory semi-sextile with Saturn.
A second case scenario could be the following.
The male is once again Saturn of he 6th and in the 6th, vey intent on his work. But this time we take the 6th from the 6th, who is HIS co-worker, namely the dreaded lady. This would be the radical 5th house. Here we see her in a stronger position with north node helping her out. Her ruler is now mercury, in spiteful scorpio, approaching an opposition to Uranus, which recalls the mars/uranus energy in her natal chart.
Now however we also see a different picture, because Uranus is in his 5th house, ruled by Venus, who approaches Saturn by square. He isn't interested in any advances on her part, especially since Venus also rules his MH and reputation !
Moon is always important in the chart. In the first case scenario it rules the "other".
In this case it remains as co-significator of you, who asked the question. And moon separating from the square with Neptune in his 3rd house of gossip makes us wonder how you are involved in the picture here? Have you been talking to anyone about this situation, or carrying words to him, that created confusion and might have been misleading?
So, will any of this lead to violence? That would normally be mar's role, but we see that mars is now direct, in its own sign, so behaving well, and in the males's 4th house, ending things. But it doesn't connect for quite a while with the Capricorn stellium, and it won't catch up with Saturn who will leave the sign before the aspect occurs.
So, Saturn does not receive any aspect from violent mars.
