well there should be exceptions to those rules like lets say if you become leader of the faction somehow you shouldn't be required to do it but if you dont show up sometimes people wont respect you as the leader if you never show up

Faction leadership will be something entirely different. Instead of getting these jobs, you will be giving them out. If you don't, your faction will be less successful and other faction members might try to take the power from you.
That said, you won't be able to lead every faction. Most factions will only allow you to become the second in command and you will get promoted into a leader position in one of the ending sequences, or in the post game.
