Shulchan Aruch O.C. 53:4-5 discusses some qualifications for an ideal shaliach tzibbur as well as other "non-ideal" qualifications. It seems that one necessity is that the congregation prefers him and is satisfied with him.
WHat happens if the shaliach tzibbur has been in that shul for many years, and there is a group of "old timers" who regularly attend the shul (every Shabbat and Yom Tov when this Shaliach tzibbur leads the service and want to keep him. The shul board members, who have the power to vote on their staff consists primarily of people that don't attend shul regularly - perhaps once every few months - want to get rid of him.
Can the board members make this decision to fire him because according to them, he is not "preferable"? Or does the halacha follow the minority of people who regularly attend and listen to him more often? Essentially, my question focuses on whether the definition of "preferable" as mentioned in Shulchan ARuch include a definition of thiose who actually benefit from his voice by attending shul more regularly.
