I'm in RCIA and my sponsor is not showing up as much as I need him?

I think that you should feel free to discuss with him how you are feeling and ask him if he could please try to attend with you if at all possible. Explain to him that you understand he works alot. Let me say that as a Catholic he is supposed to attend m on Sunday and therefore if he could find a way to attend m with you and the scrutinies at the same time that would be great. I am a sponser with the RCIA and I always try to attend with my catechumen. I accepted the responsibility with much committment. God Bless....
