じゃあ私早退の子の連絡しなきゃいけないから

The teacher says this at the beginning of the scene, with no further context

I'm confused about the use of 早退の子の連絡 here. Specifically I don't see how の連絡しな
works?

How does の連絡しな work in じゃあ、私早退の子の連絡しなきゃいけないから?
早退の子の連絡 refers to informing the student who left early about tomorrow's
homework or textbooks they need to bring. It would have been clearer to say
早退した子への連絡 instead, but since this is a common practice at least in Japanese
schools, a brief expression like this is sufficient to convey the meaning.

With this in mind, the overall structure of the expression is exactly the same
as [部屋の掃除(を)する](https://japanese.stackexchange.com/q/26120/5010) or
[英語の勉強(を)する](https://japanese.stackexchange.com/q/4006/5010).

> じゃあ私早退の子の連絡しなきゃいけないから。  
>  = じゃあ私は、早退した子 **への** 連絡 **を** しなきゃいけないから。  
>  = じゃあ私は、早退した子 **に** 連絡(を)しなきゃいけないから。

> I have to call/contact a student who left early.
