That is very dependent on the dept. I have worked some places where it was allowed, and if they had a fight prior to coming into work, it made for an absolutely miserable shift for everyone. Yes, it convenient for them, but heaven help you. Another dept I worked with allowed same shift, but not same station. Another allowed same shift, but not partners. Just depends on the dept and what they want to tolerate. Frankly I think husband/wife teams on same shift or as partners is just a recipe for a disaster. We had one dept that had two husband and wife teams - both in the middle of a divorce, and working on shift with them was absolutely miserable to the point almost everybody was applying for transfers and eventually led to splitting them and placing at entirely different stations. It's not fun. Just better not to start it, then try to fix it later.
