Narrative: After several discussions and phone calls on 5/X/21 it was concluded that the A Flight Attendant was being replaced and not work 5/Y/21 ZZZ-ZZZ1-ZZZ2. Another FA (Flight Attendant) who was scheduled to work 5/Y/21 ZZZ-ZZZ3-ZZZ2 would replace our A FA. At first the C FA and myself (B FA) thought the A FA would have to DH (Deadhead) on our flight and both the C FA and myself decided to take an earlier van ride to avoid any further distress caused by the A FA. But once C FA and myself realized the A FA was to work ZZZ-ZZZ3-ZZZ2 the C FA and me were relieved and comfortable to take the original van time of XA30am. When van came to pick up the D FA; C FA and myself our original A FA showed up as if nothing happened the previous day. On the previous day once the entire crew arrived to the hotel the A FA verbally attacked the Captain and First Officer. The A FA's hostility towards the pilots made the entire crew uncomfortable. I myself was visibly shaken by the A FA yelling and verbal attack on the pilots. Upon arriving to the airport the A FA walked off without us like the previous two days leaving us behind. When the C FA; D FA and me got to the gate the pilots were waiting in the gate area for us to discuss what we all were going to do as we were all in shock that the A FA was back on the trip without our knowledge of any change. The Captain was still backing up the decision to have the A FA removed but then it came down to what to do. The company put us in a situation making us work with the A FA whose behavior distressed the crew enough to adversely affect our work and well-being at work. The company's decision to have the A FA continue to work the flight created an unhealthy work environment. The crew was nervous and uncomfortable not knowing if there were to be another disturbance. It wasn't as if the flight was only an hour long we were flying across the ocean with nowhere to land if another disturbance were to arise. The C FA; D FA and myself all stayed away from the A FA as much as possible to avoid any further outbursts.


Second narrative: The day prior after landing in ZZZ and arriving at the hotel; I; as well as the entire crew; had a situation happen with the A Flight Attendant. After speaking with the Chief Pilot as well as the Supervisor in the Operations Center; the decision was made to have the A Flight Attendant removed from her next flight. This decision was reached between the Supervisor and the B FA and C FA. I informed the Supervisor that I even thought I was OK with flying back with the A Flight Attendant. The B and C Flight Attendants were not; and that I was backing them up and would not force or require them to fly with her; against their wishes. The Supervisor said she would pull the A FA from the trip and we would have a new A FA. The situation was so bad that the B FA and C FA did not want to ride in the same van with the A FA the next day. The following day; when we reported for work; we found out that someone had put the original A FA back on the trip without notifying myself or the rest of the crew.I personally found out 45 minutes prior to departure; when I was given the paperwork to review and noticed her name on the Crew sheet. The B; C and D Flight Attendants were extremely upset about the situation and they were put in a very difficult position standing at the gate with over 160 people who were traveling back to the mainland. I asked the 3 Flight Attendants if they were going to be able to work with the A FA and also called the Operations Center to inform the Chief Pilot and the Supervisor about the situation. After the B; C; and D Flight Attendants agreed to work with her and we departed ZZZ. Upon our arrival in ZZZ2; the B FA informed me that it was a very awkward situation.
