The thing is , first I loved Jellico, and in situations like the Federation, over time Jellico would have been able to reassign crew members to get the type of crew that fit his command style.
Picard was able to pick his primary officers, and after that those department heads would have say in getting or getting rid of people that worked with them.
You certainly don't want to be on board a ship that Captain and department heads are working against each other.
Riker's was right about that. But here the thing, he doesn't have to. Unless he is violating rules, his crew is supposed to follow his ways, even if they don't personally agree with them.
