How to interpret 分 in the following passage


> 報酬 **分** は働かせてもらうよ。もちろん追加をもらえりゃあ、その **分** よく働くってもんさ。

The first sentence is ambiguous to me. Is the second sentence actually an
explanation of the first sentence here, i.e. "let me work the amount
appropriate to the amount that you pay me" and that the first 分 and the second
分 are being used in the same manner here?

There is a later passage with a similarly ambiguous statement:

> 出撃の時はあたしに任せな。報酬 **分** はきっちり働くよ。こう見えて、雇い主を満足させる女なのさ。

Thanks for any help.




Both instances of 分 are essentially the same, it's a noun/suffix meaning
"amount that corresponds to ～", "～'s fraction", "～'s worth (of something)".

  * 報酬分: (amount of) work that corresponds to my reward; work worth my reward
  * その分: (amount of) work that corresponds to 追加 (additional reward); according to the extra payment

This person is basically saying the more she is paid, the more earnestly she
will work.
