Time spent on work and on family often comes at each other's expense.
Tips
usage
Use 此消彼长 when two quantities trade off against each other. Compare 此起彼伏 (cǐqǐbǐfú), where two things rise and fall in alternation but not necessarily in opposition.
memory
Read literally: 此 this + 消 shrinks + 彼 that + 长 grows. A perfect see-saw.
