What the difference between 賃金 and 給料?


I was reading 二銭銅貨 from 江戸川乱歩, and the words 給料 and 賃金 occurred :

> 芝区のさる大きな電機工場の職工 **給料** 日の出来事であった。

I understand 給料日 as the "pay day", or the day the worker receive their salary.

>
> 十数名の賃銀計算係が、五千人近い職工のタイム・カードから、それぞれ一ヶ月の賃銀を計算して、山と積まれた給料袋の中へ、当日銀行から引き出された、大トランクに一杯もあろうという、二十円、十円、五円などの紙幣を汗だくになって、詰め込んでいるさなかに、事務所の玄関へ一人の紳士が訪れた。

In that sentence, 賃銀 is the old form of 賃金.

What I don't understand is the difference between 給料 and 賃金 in that context.
My dictionary both translate them as "salary".




Subjectively, my sense is that [賃金]{ちんぎん} is closer in nuance to the English
term _wages_ (money paid for a specific unit of work, not necessarily
ongoing), while [給料]{きゅうりょう} is closer to _salary_ (money paid for a specific
unit of time, usually as part of an ongoing contract). Much as in English,
I've seen a certain amount of overlap between these two. That said, I'm not a
native speaker of Japanese, and I may have gotten the wrong end of the stick
at some point.
