Air carrier first officer reported the captain of the flight created a 'toxic' cockpit environment.

Narrative:

ZZZ-ZZZ1 turn. I was already at the cockpit loading the box when the captain arrived and the first introduction was an accusatory; 'so what's your story?' I was confused at first; but then realized captain wanted to know how long I had been in the right seat. I explained I was a displaced captain bumped to the right seat. [We discussed a recent change in company employment strategy.] captain then told me [opinion of the change] and that for the remainder of the day I was only allowed to talk if it pertained to the current flight. Captain would fly both legs. I told captain ok and did my best to be good pm on the first leg. Uneventful flight to ZZZ1. I hoped that the initial brief was an uncharacteristic frustration captain didn't like and by the second leg we could return to a professional cockpit. Unfortunately; this was not the case. I tried again to be a good pm on the way back; but my frustration had grown to the point I was at best a first officer trying to make sure we didn't violate any fars. Fortunately it was a beautiful night and no issue came up. On the final post flight debrief captain asked if I had any inputs. I told captain [you have] a very toxic cockpit and as a professional I deserved the respect my experience brought to the flight. Captain told me that was my opinion and we parted ways.
