I think it is just an overall change in the FO's attitude. Maybe it is just how this new generation is. It's like when you are a kid you think you know more then your parents. lol I have noticed the lack of respect with several FO's. The majority are awesome however. But some don't listen and want to prove how much they know. They do things without Captains permission in many ways when all they had to do to show respect was to just ask and most all captains are cool. This also is a lack of CRM. Stepping on your Captains feet is not cool tho. Bottom line, no matter how good you think you are or how right you think you are you should always be in the learning mode and should be in that mode forever even as a Captain. I still learn from my FO's, my mistakes, and anything new that comes along. Being humble is the best way to be.
