應該用nor / or

其實用nor或or都可以，只是nor的語氣要比or更強
牛津出版的Practical English Usage就有以下解釋
nor可用於not後面，尤其是在停頓之後。這比or語氣更強調
She didn't phone that day, nor the next day.
（比．．．that day or the next day 更強調）
Our main need is not food, nor money. It is education.

希望幫到你！

樓下captainkirk2047所講甚是，other應作others

但對一定要寫成nor do they work則有點異議
Yahoo字典在nor條下，就有一例

2. (用在not,no,never之後)也不
The story is not interesting nor instructive.
這個故事沒有味道,也沒有教育意義。
I have never spoken nor written to her.
我跟她從來沒說過話,也沒寫過信。

意下如何？

They don't help other NOR work.

Remember this,
