Hubby's Job Dilemma

I am not sure if you call it dilemma, but for my husband, this is a serious decision that is not to be ignored. We have been talking about this last week and he revealed to me he is having difficulties dealing with his boss - Jim. I know him and met him personally and he seems to be a nice guy, quiet but serious most of the time. He talked to Jim's boss, - Paul, and also happens to be our friend. Paul is both Jim's and my hubby's boss. Paul is a soft spoken guy, cool and easy to get along with. I even feel more comfortable talking with him compared to Jim.
Jim has been getting tight on my hubby, and he always wanted my husband to stay at the office all the time, which became a conflicting issue between hubby and him because hubby's job is not that way. Many of the staff know hubby is on the field most of the time because that is his job calling. Everybody in the department knows my husband and has been a good worker ever since. I can attest to that because he has been recognized almost several months a year, attending some awarding ceremonies just to let me see him accept his awards and plaques. My husband was able to open up this conflicting issue with Jim to his work mates and most of them don't like Jim either. Even before the issue broke out, I sometimes hear Janell complaining about Jim's attitude.
Yesterday, hubby finally talked to Paul and his decision is to move him to a different unit, same department. Another thing is that Paul assured him he would be promoted to grade 14 and can still do the same job routines he usually does and that includes travelling. Hubby told Paul he can still be willing to take another chance to work this with Jim because he loves where he is right now. In fact, his buddies there were upset upon learning about the news of his moving.
He asked me my opinion about this and I told him, if Jim would be seeing him as a "headache" in his unit, then why take another chance? The offer was actually better because his future boss, - Bob is a guy much better than Jim...at least that's how I was being told. But I asked him if he talked with Jim about trying to work the things out and he was saying yes, he was willing... but Paul said he will be moving him anyway.
This is still under negotiation. I am praying and we are both praying together. He was already deeply attached to where he is right now and I understand how he feels. But everything happens for a reason. His moving will be a benefit for him, I suppose.
