I've been in workplaces where bosses don't listen when employees who know their jobs tell them an idea they have is a bad one, because they're the boss and that's that. Usually things would've worked out better if they'd listened to the employees.
Was one of those workplaces on the flagship of the United States, and was it heading into a potential deadly environment, where the new 'boss' needs to feel familiar with the ship extremmely quickly?
Sorry, but this is different from a boss and a job. To start with, what the hell did Riker or anyone else feel they were going to accomplish by questioning Jellico's authority so openly? Did they think he was going to just give in, or did they imagine if they shouted loud enough Starfleet would just send in someone else? Even if the Enterprise crew were totally in the right, theres such a think of making the best of a bad situation, they knew that things could get heavy, and they should have got the idea that Jellico is not going to be changing his mind on stuff, so just STFU and do it. They arent going to make the situation any better by throwing more spanners in the works.
Apparently,if you're a boss and ALL your subordinates, competent professionals all of them, tell you that an idea or proposal is a BAD or impractical idea, and you ignore all of them and say "I don't care what advice and input I'm getting from my employees who know their jobs, I'm the boss, DO IT!" that means your being a good leader.
Jellico is pretty nice to Riker at the start, the first thing he says to Riker is:
'William T. Riker class of '57, graduated 8th in his class. Im looking forward to serving with you commander!'
Jellico then gives Riker and run down of what he wants, and then asks how he likes to be addressed. Among his list going to a four shift rotation. Its only hours later that Riker feels the need to tell Jellico he hasnt done it:
Riker: 'I was actually going to talk to you about Delta shifts a little later, sir. Right now Gamma shift will be on duty when we arrive and I will tell Lieutenant Mcdowall about the probe'
Riker doesnt even apologise! Hes let Jellico walk around thinking his orders are in place and saying nothing, he just figures he'll talk about it later. Its only after this that Jellico starts to come down on him, and who could blame him? When a ship fails in its mission that failure comes down on the head of the captain, its his responsibility and its his fault if things go wrong. His authority is given to him due to years of command because the people with even more experience than him think that he can handle the responsibility. In this case the responsibility was that of the Enterprise, the lives of everyone on board, and even the fate of the Federation. That responsibility is his, not Commander Riker's, or Geordi's, and to screw around behind his back is unacceptable. Nothing Jellico gives the crew to do is unattainable, and hes doing it so that he knows he'll be fully aware, and fully confident, in the functionings of the ship if it turns out he needs to captain it in action.
