Attaches to	Form	Example
Noun (forming fixed compounds)	N + 上（じょう）	仕事しごと上 / 健康けんこう上 / 立場たちば上

When: Formal and written, in set compounds (法律ほうりつ上, 教育きょういく上, 経験けいけん上). Not freely attached to any noun the way 〜について is.

健康けんこう上じょうの理由りゆうで退職たいしょくした。

He resigned for health reasons.

立場たちば上じょう、その質問しつもんには答こたえられません。

Given my position, I can't answer that question.

Read じょう, not うえ. The reading matters: 〜上じょう means 'in terms of ~,' while 〜上うえで means 'after / upon doing ~' — same kanji, different grammar.

Jengo shows 〜上 the way you actually meet it: inside real Japanese sentences, so it sticks instead of staying an abstract rule.
