I dunno, maybe try to leave your old floor job behind you and keep on moving in engineering. You won't be able to be one of "them" and one of "us".
Are "they" production line electricians? Do they have a direct supervisor that they are accountable to? Is that supervisor you? If you are in engineering, is it S.O.P. for you to visit the floor and direct the work of the electricians, or should you let their supervisor/shift leader do that, or notify the Q.A. folks so they can catch it? Most professionals know how to behave on the job, but if it must be done and they refuse to do it(any production job I ever had would have given a "write-up' for that)...
Sounds like you'll have static any way you do it. Good Luck
