Love in the workplace

Had to make a trip to Pittsburg, KS this week. This is home to one of my best accounts.(for my other accounts that might be reading this....You know I really love you more!)
The manager loves our company and the people that work for us. There are never complaints and only praises. He says that all companies should have people like this.(they do) The issues have to do with the two women that work for me. They love their job. They love me. ( I mean, would someone tell someone that they loved them if it weren't true?) They hate each other. They can't stand each other. They will eventually have a true crime book written about the murder of one of them.
"R" only speaks spanish only and "J" only english. (this has the makings of one of those logic riddles) Actually, I think that they are bi-lingual(not that it's my business what people do in their own home) but, this gives them reason to ignore, be uncooporative and insult each other.
R will tell me that she supects that J has put sugar in her gas tank. I will tell J that R says someone put sugar in her gas tank and J will say "She'll probably blame me." J will say that R is lazy and not pulling her weight and when I tell R that we are expected to work our fair share, she'll say "Dejara de llegar ella tarde y saliendo temprano?" (I think that means -I really do love you!)
So, I had this come to Jesus talk with them and there were insults thrown about, "Fat pig!" "Lazy pig!" "Stupid pig!" (and then they started in on each other) I was able to make some head way by agreeing to lose weight, be productive and knowledgeable and they agreed to give me exclusive rights to the murder story.
