Daughter track is a career path where a woman reduces her chances of advancement by working flextime or fewer hours to look after her elderly parents.
“女兒職業道路”是指女性為照顧年老的父母，利用彈性時間工作或減少工作時長，從而減少了自己職業晉升機會的一種職業發展道路。

Daughter track這個詞與mommy track（母親職業道路）相對，后者指母親為照顧孩子而采取的同樣做法。

Example:
The survey found that women were more likely to shoulder responsibilities for caring for the elderly and take a so-called "daughter track" approach, in which their careers are slowed as they juggle work and parental care.
研究發現，女性更可能肩負起照顧老人的責任，走上所謂的“女兒職業道路”。她們力圖兼顧工作和照顧父母，但職業發展卻因此受阻。
