You have this right, but generally you won't interfere, because there must be his reasons why the party branch secretary doesn't sign. The superior can intervene, but generally you won't. Unless the relationship with party member is really hard, there's a saying that if you don't reach the designated position, you won't seek the government, so your superiors rarely intervene for someone, because it's not his business.

Secondly, the party branch secretary who is preparing to become a full member of party member doesn't sign, unless he forgets, otherwise the party branch secretary thinks that there is still a problem in preparing party member, maybe it is a problem of interpersonal relationship, maybe it is a work ability or something.

But compared with the formal party member, the preparatory party member has everything except the right to vote and stand for election. Generally speaking, sooner or later, we must become a full member.

I don't know why, but I can only answer objectively. If you want deeper help and help you analyze the problem, please keep asking me.
