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(yè)道路”是指女性為照顧年老的父母，利用彈性時(shí)間工作或減少工作時(shí)長，從而減少了自己職業(yè)晉升機(jī)會(huì)的一種職業(yè)發(fā)展道路。

Daughter track這個(gè)詞與mommy track（母親職業(yè)道路）相對(duì)，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(fā)現(xiàn)，女性更可能肩負(fù)起照顧老人的責(zé)任，走上所謂的“女兒職業(yè)道路”。她們力圖兼顧工作和照顧父母，但職業(yè)發(fā)展卻因此受阻。
