Need advice

I started working in a diagnostic cath lab a couple of years ago. At that time we had 5 RNs and 1 Rad Tech. We averaged 3-4 caths/day. All the RNs rotated through bio, circulating, and scrubbing with the rad tech scrubbing or doing bio. The rad tech was a psycho. I mean this literally. (The things that he would do...sick.) He finally snapped at work one day in the cath lab and was immediately fired and escorted off the hosp grounds. As he was leaving, he was threatening all of us. I truly felt that he would come back with a shotgun. We were escorted to our cars every evening for a while. It was very trying on all of our nerves. Of course, we were told not to repeat anything that had happened. We were only to say "**** no longer works in the cath lab. If you need to know why he no longer works here, you need to ask him." In the year since he was fired, we were moved to a new area in the hosp. down by radiology. It has been very hard to work here. The manager of radiology thinks the lab should be full of rad techs, not RNs, so he treats us very rudely. Plus, all the rad techs think we got "you know who" fired just because he was not an RN and they barely tolerate us. Once when their lab broke down and they had to borrow our lab for a procedure, the snide comments and rude remarks were embarrassing. We were doing everything they asked, trying to get along and mend bridges, but they continued to try to make us look stupid.

So the advice I need? Our manager is being promoted to Director of Cardiac Services and rumor has it that the manager of radiology will in all likelyhood become our manager. This was told to me by a rad tech (one of three that talk to us) and that he planned to fire three of us and replace us with rad techs and then the remaining 2 nurses would only be allowed to circulate. And I can only imagine how the remaining nurses will be treated. We realize that having a cath lab staffed with RNs only is unique. I will be one of the RNs remaining in the lab due to senority. I just worry about how I will be treated. I love to scrub but will give it up willingly just to get along. Any advice out there?
