I have been working in a dysfunctional flight department. I flew an aircraft without being sure that the MEL was done correctly. It originally became nonfunctional as I was flying with the Chief Pilot; and I asked him how we should write it up. He asked; officially or unofficially. I said officially; and thought the matter was going to be resolved before we flew it at altitude again. It was not and I flew with the O2 nonfunctional. There are a number of issues at this flight department; and I have reported it to the management; and the POI (Principle Operations Inspector).
Flight Department Captain reported flying an aircraft with a non-functional O2 system and not knowing if the MEL for it had been followed correctly.
