I was reading in Donna McCrohan's book The Honeymooners Companion that Jackie Gleason was demanding and a perfectionist and had a high writer turnover rate. In another book, I also read that while filming the show, Gleason wouldn't stop the action for any reason, regardless of mistakes.

So that led me to ask was Jackie Gleason a difficult person to work with or work for?

That is the rumor. On Shout! Factory's Sid Caesar box set, Mel Brooks makes reference to the way Gleason treated the writers. Apparently he used to tear up scripts he didn't like.
